2x2-7x-12
14p = 42
p = 3
open
Dependent
what is the y-intercept
y=2x-4
Write an equivalent expression
2x-10
x-5
or
4x-20
-2x - 7 = 15
> has an open or closed circle
closed
Given the equation h = 2d + 1
What is the independent variable?
y=-2x+3
What is the slope
-2
6(-4+10x)
-24+60x
15x + 20 = 85
x = 4
If you divide/multiply by a negative number in an inequality, what happens to the sign
It changes direction/flips
Given the equation h = 2d + 1
What is the dependent variable?
h
y=mx+b
what letter represents slope
m
What missing number makes this statement true
___(4+3m)-1 = 11+9m
4(6x - 10) = 8x + 40
x = 5
Solve
