Distribute
remember a(b+c)=ab+ac
8(y+4)=8(y)+8(4)=8y+32
8y+32=7y+38
minus 7y both sides
y+32=38
mius 32 oth sides
y=6
Answer:
rectangular prism, 6 faces, 8 vertices
Answer:
a=69
Step-by-step explanation:
121-52 is equal to 69
You have a 33.33% chance to get it right each time
multiply 33.33%*33.33%*33.33%= .3333*.3333*.3333
it equals about 4%
The line is vertical, so the slope is infinite
Step-by-step explanation:
Given two points with coordinates
and
, the slope of the line passing through the two points is given by the equation
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
In this problem, the coordinates of the two points are:
![(x_1,y_1)=(-4,-2)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%28-4%2C-2%29)
and
![(x_2,y_2)=(-4,-22)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%28-4%2C-22%29)
which means:
![x_1=-4\\y_1=-2\\x_2=-4\\y_2=-22](https://tex.z-dn.net/?f=x_1%3D-4%5C%5Cy_1%3D-2%5C%5Cx_2%3D-4%5C%5Cy_2%3D-22)
Substituting all these values into the equation of m, we find the slope of the line:
![m=\frac{-22-(-2)}{-4-(-4)}=\frac{-20}{0}=\infty](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-22-%28-2%29%7D%7B-4-%28-4%29%7D%3D%5Cfrac%7B-20%7D%7B0%7D%3D%5Cinfty)
The slope is infinite: this is because the line is vertical.
