Type the correct answer in each box. Use numerals instead of words. The sum of two numbers is 84. The square of the first number is 6 more than the second number. Write a system of equations to find the value of x, the first number, and y, the second number.
y = -x + ____
y = x^2 + ____
Answer:
84, -6
Step-by-step explanation:
y= -x+84
y= x^2+(-6)
The system of equations used to find the value of x is:
y = -x + 84
y = x² - 6
Let x represent the first number and y represent the second number.
The sum of the two numbers is 84, hence:
x + y = 84
y = -x + 84 (1)
The square of the first number is 6 more than the second number. Hence:
x² = 6 + y
y = x² - 6 (2)
The system of equations used to find the value of x is:
y = -x + 84
y = x² - 6

Answer: 64% of students do not own a cell phone
Step-by-step explanation:
First, take 100 and divide it by 25, since percentages are out of 100
100/25=4
Now multiply 4 by 16
4x16

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
we can find angle C b/c the angles of a triangle always add to 180 , soo
180= C + 81 +63.5
35.5 = C
now that we have angle C and we know the Hyp we can use sin to find side g
where g = Opp and Hpy = 13.8 for this question
Sin(35.5) = Opp / 13.8
13.8*Sin(35.5) = Opp
8.0137 = Opp
g = 8.0137
next they ask for the area of the biggest triangle ABC ( there are two smaller ones when you use D )
we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.
we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj
Cos(35.5) = Adj / 13.8
13.8*Cos(35.5) = Adj
11.234794 =Adj
now solve for DB using cos again but with the other smaller triangle where Adj = DB now
Cos(63.5) = Adj / 8.9
8.9*Cos(63.5) = Adj
3.971160
add these two Adjs together to get the total 'a' side
15.205954
now plug in side a as the base and g as the height of our biggest triangle
Area = 1/2 * 15.205954 * 8.0137
Area = 60.9159
rounded to 2 sig figs
Area = 60.92 :) hope you get an "A" :P
Which expression is not equivalent
to (x + 4)(x – 3)?
Answer:
A) x² + 7x - 12 is NOT equivalent to the expression.
Step-by-step explanation:
1) expand by distributing terms.
[tex] {x }^{2} - 3x + 4(x - 3)[/tex]
2) Expand by distributing terms.
[tex] {x}^{2} - 3x + 4x - 12[/tex]
3) Collect like terms.
[tex] {x}^{2} + ( - 3x + 4x) - 12[/tex]
4) Simplify.

Step-by-step explanation:
Solve for x.
Lolllllllll
Answer:
x = 15
Step-by-step explanation:
Create and solve an equation of ratios. We can do this because the smaller triangle and the larger one are similar.
x 5 + x
------- = -----------
9 9 + 3
Cross-multiplying, we get 12x = 45 + 9x,
which simplifies to 3x = 45
Solving for x, we get x = 15

Answer:
first one
relationship between base and perpendicular is
given by tan angle
tan x=P/h
remember perpendicular is opposite side of taken angle
tan x=13/8
<x=tàn-¹(13/8)=58.39°
for second one
relationship between base and hypotenuse is given by cos angle
cos G=b/h
cos G=24/32
<G=cos-¹(24/32)=41.4 is your answer

Answer:
43x+39
Step-by-step explanation:
(5)(9x)+(5)(6)+−2x+9
=45x+30+−2x+9
=45x+30+−2x+9
=(45x+−2x)+(30+9)
=43x+39
(if this helps please give brainliest and 5 stars thanks)
Answer:
43x + 39
Step-by-step explanation:
5 ( 9x + 6 ) - 2x + 9
Firstly, open up the brackets.
= 45x + 30 - 2x + 9
Now bring the like term together and simplify.
=45x - 2x + 30 + 9
= 43x + 39

What are the missing numbers?
Answer:
You can use the formula 500 * 1.03^x to solve for any year.
year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94
Step-by-step explanation:
The amount is increasing, and there are two main ways for that to happen. Addition and multiplication. So let's see if it keeps getting the same amount added or multiplied.
0 to 1 goes from 500 to 515, so 15 is added. but 15.45 is added from 1 to 2, so we can't just do simple addition.
using multiplication 0 to 1 has 1.03 multiplied. if you multiply by it again you do get 530.45, so we have established what is happening.
You can use the formula 500 * 1.03^x to solve for any year.
so year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94

The volume of clay sculpture is 540 cubic inches.What is the volume of similar sculpture that is smaller by a scale factor of 1/2.
Answer:
67.5 in³
Step-by-step explanation:
Given that :
Volume 1 = 540 in³
Volume 2 of similar shape = x ; if the scale factor = 1/2
Volume of a shape = length * width * height)
The scale factor = 1/2
Volumetric factor = 1/2 * 1/2 * 1/2 = 1/8
Hence, the volume of similar sculpture will be :
540 in³ * 1/8 = 67.5 in³
