A direct variation function contains the points (-9, -3) and (-12, -4). Which equation represents the function?
y = -3x
y=-
o ya
y = 3x
Answer:
[tex]y=\frac{1}{3} x[/tex]
Step-by-step explanation:
we need a function that when we plug the value of x, we get the given value of y.
In the coordinate point
(-9, -3)
the x and y values are:
x = -9
y = -3
so we can see that the value of y is one third of the x value (because -9/3 = -3):
[tex]y=\frac{1}{3} x[/tex]
this is also true for the secod point:
(-12, -4)
here the x and y values are:
x = -12
y = -4
again the y value is one third of the x value (because -12/3 = -4):
[tex]y=\frac{1}{3} x[/tex] ⇒ this is the equation that represents the function.
Quadratic equation in standard form
x^2-9=0
Answer:
x^2 + 0x - 9 = 0
Step-by-step explanation:
x^2-9=0 is already in standard form for a quadratic. If desired it may also be rewritten as x^2 + 0x - 9 = 0
The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same.
Write an equation which tell the price Y for the number of markers X.
Answer:
Step-by-step explanation:
let x represent the number of markers.
Let y represent the cost for x boxes of markers.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (14 - 7)/(24 - 10)
m = 7/14 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 24, y = 14 and m = 0.5 into y = mx + c. It becomes
14 = 0.5 × 24 + c = 12 + c
c = 14 - 12
c = 2
The equation would be
y = 0.5x + 2
y=-4x+2
y = 6.x-8
I don’t understand
Answer: (1, -2)
Step-by-step explanation:
If you think about that plot from two lines crossed each together, so I have a deal for you, that answer might be (1, -2).
Use emlimination to solve the system x-5y=20 and x+3y=-4 for x
Answer:
y=-3 , x=5
Step-by-step explanation:
x-5y=20 x-5y=20-(x+3y=-4) new -x-3y=4
x-5y=20
-8y=24
-8 -8
y=-3 x-5y=20
x-5(-3)=20
x+15=20
-15= -15
x=5
The value of x is 5 for the system of equations [tex]x-5y=20[/tex] and[tex]x+3y=-4[/tex].
The given system of equations are :
[tex]x-5y=20[/tex] ...(1)
[tex]x+3y=-4[/tex]...(2)
To solve the equation, multiply equation (2) with -1.
[tex]-x-3y=4[/tex]...(3)
Add equation (1) and (3):
[tex]x-5y-x-3y=20+4[/tex]
Combine like terms:
[tex]-8y=24[/tex]
Divide both sides by -8:
[tex]y=-3[/tex]
Now, we substitute the value of [tex]y = -3[/tex] into either of the original equations to solve for x.
[tex]x - 5(-3) = 20[/tex]
[tex]x + 15 = 20[/tex]
[tex]x = 20 - 15[/tex]
[tex]x = 5[/tex]
Therefore, the solution to the system of equations is[tex]x = 5[/tex] and [tex]y = -3.[/tex]

Step-by-step explanation:
The selling Price is $33.75.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A music store bought a CD set at a cost of $25.
Markup Percent= 35%
Now, the Selling Price
= 25 + 25 x 35%
= 25 + 25 x 35/100
= 25 + 25 x 0.35
= 25 + 8.75
= $33.75
Hence, the selling Price is $33.75.

Step-by-step explanation:
(log 0.04 − 2 log 0.3) / (1 − log 15)
Change 1 to log 10.
(log 0.04 − 2 log 0.3) / (log 10 − log 15)
Use log property: a log b = log bᵃ.
(log 0.04 − log 0.09) / (log 10 − log 15)
Use log property: log a − log b = log (a/b).
log (0.04/0.09) / log (10/15)
Reduce fractions.
log (4/9) / log (2/3)
Change 4/9 to (2/3)².

From the hay loft door, Ted sees his dog on the ground. The angle of depression of the dog is 40º. Ted's eye level is 16 feet above the ground. How many feet must the dog walk to reach the open barn door directly below Ted (to the nearest foot)?
Answer: 19 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of depression of the dog, the opposite side (16) is Ted's eye level above the ground, and the adjacent side (x) is the distance between the dog and the barn door.
Replacing with the values given:
tan40 = 16/x
Solving for x
x =16/tan40
x= 19 ft

Step-by-step explanation:
A prism with a square base has a volume of 96 ft3. The height of the unit is 6 feet.
A prism has a length of l, width of 2, and height of 6 feet.
Given what you know about the figure, complete these sentences.
The area of the square base is feet2.
The length of the prism is feet.
The width of the prism is feet.
Answer:
The area of the base is 16 ft^2
The length of the prism is 4 feet.
The width of the prism is 4 feet.
Step-by-step explanation:
The formula for volume of a prism is given by
V=Bh where B is the area of the base and h is the height
96 = B h
We know h is 6
96 = B6
Divide each side by 6
16 = B
The area of the base is 16 ft^2
Since the base is a square
B =16ft^2
since it is a square, the area is given by
B =s^2 where s is the side length
16 =s ^2
Taking the square root
4 = s
The length of the prism is 4 feet.
The width of the prism is 4 feet.
Answer:
1. square base = A = 16 ft² (Base area of square prism)
2. Length of prism = 4 ft
3. Width of prism = 4 ft
Step-by-step explanation:
given:
Volume of a square base prism (V) = 96 ft³
height (h) = 6 ft
Length (L) = L
Width (W) = W
find:
1. square base
2. Length of prism
3. Width of prism
---------------------------------
1.
Vol of prism = base area (A) x height (h)
V = A * h
96 = A * 6
A = 96 / 6
A = 16 ft² (Base area of square prism)
2.
Length of prism = A = s²
16 = s²
s = √16
s = 4 ft.
therefore the Length of a square base prism = 4 ft
3.
square base = L = W
therefore the Width of a square base prism = 4 ft

did Lightning break Tillman’s record for fastest dog on a skateboard? Explain how you know.
Answer:
no, the first dog is faster
Step-by-step explanation:
the first dog went 5m in 1 second that means he can go 75m in 15 seconds. the other dog went 75m in 15.5 seconds.
Write the equation of the function when y=xl is translated 1 unit up and 6 units to
the left?
Oa) y = |x – 6|+1
Ob) y = |x – 1| +6
Oc) y = |x+1|+6
d) y = |x+6|+1
Answer:
Option d) is correct
Step-by-step explanation:
Given: [tex]y=\left | x \right |[/tex] is translated 1 unit up and 6 units to the left
To find: equation of the function when the given function is translated 1 unit up and 6 units to the left
Solution:
See the graph of [tex]y=\left | x \right |[/tex] .
As the graph of the given function is translated 1 unit up and 6 units to the left, the graph becomes as shown in the image attached.
The equation of the function when the given function is translated 1 unit up becomes [tex]y-1=|x|[/tex] and when this function is translated 6 units to the left, the equation becomes [tex]y-1=|x+6|[/tex]
[tex]y=|x+6|+1[/tex]
So, option d) is correct.
A recipe says to use 1.5 cups of flour to make 24 cookies. What is the constant of proportionality that relates the number of cookies made, y, to the number of cups of flour used, x? a. 0.6 b. 3 c. 24 d. 16
Answer: 16
Step-by-step explanation:
The constant of proportionality is a ratio that exist between two directly proportional quantities. From the question, recipe says to use 1.5 cups of flour to make 24 cookies.
y = the number of cookies made
x = the number of cups of flour used
y = kx
k = y/x
k = 24/1.5
k = 16
Therefore, the constant of proportionality which relates the number of cookies made, y, to number of cups of flour used, x is 16.

What is the length of AC?
Round to one decimal place.
Answer:
x = 5.7
Step-by-step explanation:
Use the Triangle-Angle-Bisector Theorem.
[tex]\frac{CD}{DB}[/tex] = [tex]\frac{AC}{AB}[/tex]
Substitute the corresponding side lengths.
[tex]\frac{2}{2.8}[/tex] = [tex]\frac{x}{8.1}[/tex]
Cross Multiply.
16.2 = 2.8x
Divide each side by 2.8.
[tex]\frac{16.2}{2.8}[/tex] = [tex]\frac{2.8x}{2.8}[/tex]
Since 2.8 cancels out 2.8x, your left with x.
Then divide 16.2 by 2.8.
x = 5.7
