First you have to put it into slope intercept form. You have to put it into y = mx + b then m is the slope and b is the y intercept on the graph.
Answer:
R=12 is the solution
I don't know how to explain but it needs to be 20 characters
Answer:
2x - 2y
Step-by-step explanation:
P = 7x + 2y
P =a + b + c
7x + 2y = 2x + y +3x - 5y + c
7x + 2y - 5x - 4y
= 2x - 2y
Answer:
D :If 4x + 12 ≠ –4, then 3x + 7 ≠ −5.
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Using ΔAHC , then
∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x
∠ECD = ∠ACB ( vertical angles are congruent ), thus
∠ECD = ∠ACH + ∠HCB, that is
3x = 80 - 2x + x
3x = 80 - x ( add x to both sides )
4x = 80 ( divide both sides by 4 )
x = 20
