1+6=4y-3y
y=7
2+6x=1-x
6x+x=1-2
7x=-1
x= -1/7
5y+4=4y+5
5y-4y=5-4
y=1
Answer:
D
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (-3, - 2)
m =
=
← undefined
Note that division by zero is undefined thas the slope is undefined.
This indicates that the line going through the 2 points is vertical and parallel to the y- axis.
Answer:
3x^2-x+5.2f\left(-3\right)-f\left(4\right) =
3x^2-x-19.6f
Step-by-step explanation:
3x^2-x+5.2f\left(-3\right)-f\left(4\right)
=3x^2-x-5.2f\cdot \:3-f\cdot \:4
=3x^2-x-15.6f-4f
=3x^2-x-19.6f
Answer:
3
Step-by-step explanation:
Any number and variable combined is a term.
So 8 (#1 - Constant), + 19y (#2 -Coefficient + Variable), - 4z (#3 -Coefficient + Variable)
3 terms - B
