Assuming that
![x](https://tex.z-dn.net/?f=x)
is the amount of hours spent doing homework:
Plug in
![3](https://tex.z-dn.net/?f=3)
for
![x](https://tex.z-dn.net/?f=x)
![y = 8(3)+40](https://tex.z-dn.net/?f=y%20%3D%208%283%29%2B40)
,
![y=64](https://tex.z-dn.net/?f=y%3D64)
That means that since a
![y](https://tex.z-dn.net/?f=y)
value is the test score (because that's what the y-axis is labeled), your predicted test score is a
64.
X=8 would you like me to explain why?
Answer:
(x+10)+(×+50)=180(exterior co- interior angel
2x+60=180
2×=180-60
×=120/2
×=60
(6x+3)=(7x-12)(corresponding angle )
3+12=7×-6×
x=15
4x-2=3x-19(vertically opposite angle)
4x-3×=-19+2
x=-17
Answer: False
Step-by-step explanation:
398 + 9 = 407
400 + 8 = 408
If the equation was 398 + 10 then yes it will be equal to 400 + 8
Answer:
Step-by-step explanation:
-2(4-3x)+(5x-2)
-8+6x+5x-2
11x-10
