10x+9=4x -9 solve
please help
Answer:
x = -3
Step-by-step explanation:
To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)
Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.Subtract 4x from both sides of the equation. This gives you 6x = -18.Divide both sides by 6. This gives you x = -3The final answer is x = -3

HELP. ITS ABOUT FUNCTIONS! HELPPPPPPPPPPPPPP HELPPPPPPP
Answer:
B
Step-by-step explanation:
It cannot be C. The Y-intercept of Function W is 30, while the Y-intercept of Function Z is 15.8. Now, we are left with A, B, and D.
It cannot be D, because 30 is not less than 15.8. Now, we are left with options A and B.
Function Z as an equation is approximately y=-1/24x+15.8.
The slopes are NOT equal, so the answer cannot be A.
Explanation why it's B:
1/16 is bigger than 1/24, however, since the fractions are NEGATIVE, -1/16 is actually LESS THAN -1/24. The slopes of Function W is less than the slope of Function Z.
Answer:
B. the slope of function W is less than he slope of function Z
Step-by-step explanation:
Function W:
y= - 1/16x+30Function Z:

using the data from the table we can put the function in y= mx + b format:
x=0 ⇒ y= 15.8 ----- interceptx=1 ⇒ y= 15.7615.76- 15.8 = - 0.04= - 4/100 = -1/25 ----- slopeas per above, we get the the form of function Z
y= -1/25x+15.8we can now compare the slops and intercepts of functions W and Z
m - is the slope: -1/16 and - 1/25
-1/25>-1/16 ⇒ the slope of function W is less than Zb is the y-intercept: 30 and 15.8
30>15.8 ⇒ the y-intercept of function Z is lessAs per above the correct option is

the shapes below are drawn on a centimeter grid, show that the triangle and the square have the same area.
Answer:
Area_square = 4 cm2
Area_triangle = 4 cm2
Step-by-step explanation:
The first thing to do is calculate the area of both figures.
The area of the square is given by:
Area_square = side * side
The side of the square is 2 cm, so:
Area_square = 2 * 2 = 4 cm2
The area of the triangle is given by:
Area_triangle = base * height / 2
The base is 2 cm, and the height is 4 cm, so we have:
Area_triangle = 2 * 4 / 2 = 4 cm2
So we have that Area_square = Area_triangle = 4 cm2

If cos0 =1/3
then sin0=?
Answer:
sin θ = +/- (2√2)/3
Step-by-step explanation:
cos θ = 1/3
cos²θ + sin²θ = 1
(1/3)² + sin²θ = 1
sin²θ = 1 - 1/9
√(sin²θ) = +/-√(8/9)
sin θ = +/- (2√2)/3

You have $10,000 to invest, and three different funds from which to choose. The municipal bond fund has a 7% return, the local bank's CDs have an 8% return, and the high‐risk account has an expected (hoped‐for) 12% return. To minimize risk, you decide not to invest any more than $2,000 in the high‐risk account. For tax reasons, you need to invest at least three times as much in the municipal bonds as in the bank CDs. Assuming the year‐end yields are as expected, what are the optimal investment amounts?
Answer:
Optimal investment amount = $300
Step-by-step explanation:
discount = x
original price = 10,000
discount% = 7%
x/10,000 = 7/100
x · 100 = 7 · 10,000
100x = 70,000
100x/100 = 70,000/100
x = 700
discount = x
original price = 10,000
discount% = 8%
x/10,000 = 8/100
x · 100 = 8 · 10,000
100x = 80,000
100x/100 = 80,000/100
x = 800
discount = x
original price = 10,000
discount% = 12%
x/10,000 = 12/100
x · 100 = 12 · 10,000
100x = 120,000
100x/100 = 120,000/100
x = 1,200
So:
$1,200 - $800 - $700 = $300
We max out the high return investment, $2000 for 12%.
We have $8000 left to invest and we want to put as much in CDs at 8% as possible. Let's call b the bond investment and c the CD investment. We have
b ≥ 3c
Since munis have the lower return we want as many CDs as possible. So we choose:
b = 3c
b + c = 8000
3c + c = 8000
4c = 8000
c = 2000
That leaves b=3c=6000 for bonds.
Answer: $6000 in bonds, $2000 in CDs, $2000 in high-risk.

Answer:
6/15 * 2/14 = 12/210
Step-by-step explanation:
This is compound probability. To calculate compound probability, you need to multiply the probabilities of each event happening together.
In this example, the events are selecting a pineapple cake, then a strawberry cake.
Let's find the probabilities!
There are 2 strawberry cakes, 6 pineapple cakes, and 7 chocolate cakes. This means that he has 15 cakes in total.
Therefore, the probability of selecting a pineapple cake is 6/15.
Now, if we assume that he has selected a pineapple cake already, there are now 14 cakes.
Next, the probability of selecting a strawberry cake is now 2/14. This is because he already took a pineapple cake, and now he has to pick a strawberry cake out of the remaining 14 cakes.
Multiply these two probabilities to find the compound probability: 12/210 ( this could be further simplified, but that's how they give it to you! )

Write an expression for the situation described. Each person's share if 'p' people share 8 slices of pizza equally.
Answer:
The expression that represent each person's share is: [tex]y(p) = \frac{8}{p}[/tex]
Step-by-step explanation:
To divide a pizza, or anything else, equally among a certain number of people, we need to divide the total of pizza available by the number of people who will eat the pizza. In this case there are 8 slices and 'p' people, therefore:
[tex]y(p) = \frac{8}{p}[/tex]
In order to validate the expression, we can see that if 8 people eat the pizza, each gets one slice, because 8 divided by 8 is 1, while if 4 people eat the pizza each get 2 and so on.
The expression that represent each person's share is: [tex]y(p) = \frac{8}{p}[/tex]
URGENT: At what annual rate of simple interest must $12,000 be invested to earn $135 in interest each quarter? (I will give brainliest)
Answer:
4.5%
Step-by-step explanation:
Firstly we should understand that a quarter is every three months.
So if $135 is earned each quarter, then 4 * 135 = $540 is earned per annnum
We use the simple interest formula to get the rate.
Mathematically;
I = PRT/100
where P is the amount deposited = 12,000
R is what we are looking for which is the rate
T is the time which is 1 year
I is the interest which is 540
We can rewrite the simple interest formula to be:
100I = PRT
R = 100I/PT
Thus substituting the values we have;
R = (100 * 540)/(12,000 * 1) = 4.5%
Answer:
4.5%Step-by-step explanation:
Using the simple interest formula to tackle this question.
[tex]SI = \frac{PRT}{100}[/tex]
P = principal = $12,000
R = rate (in %) = ?
T = Time(in years) = 1/4 years
135 = [tex]\frac{12000*R}{100*4}[/tex]
[tex]135 = \frac{12000R}{400}\\ 54000 = 12000R\\R = \frac{54000}{12000}\\ R = 4.5\ %[/tex]
The annual rate of simple interest is 4.5%
Malik decides that he wants a good result on the state math test. He plans to study for at least 45 minutes three nights per week. Which expression represents Malik's study goal for each week?
Answer:
[tex]135<t_{minutes}\:<315[/tex]
Step-by-step explanation:
Malik's goal is a minimum total of 135 (45 x 3) minutes per week, in three session of 45 minutes.
Notice that it is at least.
So He can do sessions from 3 , 4, 5, 6 up to 7 nights per week
Hence, we can write his goals in minutes per week:
[tex]G_{w}=3*45<t_{minutes}<7*45\\G_{w}=135<t_{minutes}<315[/tex]

What is the sum of the greatest and least numbers below: \[8\frac15, \qquad -8\frac25, \qquad -\frac{26}{3}, \qquad -\frac{54}7, \qquad \frac{53}{6}.\]
Answer:
[tex]\dfrac{47}{42} \ \ \ \ \ OR \ \ \ \ 1.1[/tex]
Step-by-step explanation:
The objective of this question is to find the sum of the greatest and least numbers below:
[tex]\[8\frac15, \qquad -8\frac25, \qquad -\frac{26}{3}, \qquad -\frac{54}7, \qquad \frac{53}{6}.\][/tex]
To do this ; we will need to find the decimal component of each of them and equate them on a number line before summing the greatest and least numbers.
[tex]8 \frac{1}{5} = \dfrac{8*5+1}{5} \\ \\ = \dfrac{41}{5} \\ \\ = 8.2[/tex]
[tex]-8 \frac{2}{5} =- \dfrac{8*5+2}{5} \\ \\ =- \dfrac{42}{5} \\ \\ = -8.4[/tex]
[tex]-\dfrac{26}{3}= - 8.7[/tex]
[tex]-\dfrac{54}{7} = - 7.7[/tex]
[tex]\dfrac{53}{6}= 8.8[/tex]
Thus; the above decimal component of the fractions given are :
8.2, -8.4, -8.7 , -7.7 and 8.8
We are to find the sum of the greatest and the smallest number ; on a number line; we will realize that the positive side is greater than the negative side , As such the greatest number from the positive side will be 8.8 and the smallest number will be -7.7
The sum of 8.8 + ( -7.7 ) = 8.8 - 7.7
= 1.1
i.e
[tex]\dfrac{53}{6} + (- \dfrac{54}{7} )[/tex]
[tex]\dfrac{53}{6} - \dfrac{54}{7}[/tex]
[tex]\dfrac{53}{6} - \dfrac{54}{7} = \dfrac{53*7 - 6*54}{42} \\ \\ = \dfrac{47}{42} \\ \\ = 1.1[/tex]

What are the foci of the hyperbola represented by the equation (x^2)/64 - (y^2)/32 =1
Answer:
x = √2y^2 + 64 or x = √2y^2 + 64
Step-by-step explanation:
Solve for x.
x^2/64 - y^2/32 = 1
Step 1: Add 1/32 y^2 to both sides.
1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2
Step 2: Divide both sides by 1/64.
1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64
x^2 = 2y^2 + 64
Step 3:
x = √2y^2 + 64 or x = √2y^2 + 64
Answer:
x = √2y^2 + 64
Step-by-step explanation:
= 1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2
= 1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64
= x^2 = 2y^2 + 64
= x = √2y^2 + 64

You bought a magazine for $3 and two notepads. You spent a total of $13. How much did each notepad cost? *
Answer:
$5
Step-by-step explanation:
We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,
⇒ Form the equation
→ 2n + 3 = 13
⇒ Minus 3 from both sides to isolate 2n
→ 2n = 10
⇒ Divide both sides by 2 to find the cost of one notepad
→ n = 5
The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.
