y = −2x + 13
y = 2x − 3
Set the equations to equal and solve for x:
-2x + 13 = 2x -3
Add 2X to each side:
13 = 4x -3
Add 3 to each side:
16 = 4x
Divide both sides by 4:
x = 16/4
x = 4
Now replace x with 4 in one of the equations and solve for y:
y = -2(4) +13
y = -8 +13
y = 5
x = 4 and y = 5 , which is the ordered pair (4,5)
Both numbers are positive values, so the second graph is correct.
The answer to this question is z=-5
Answer:
Step-by-step explanation:
x² - 12x + a = (x + b)²
x² - 12x + a = x² + 2xb + b²
-12 = 2b and a = b²
b = -6
a = b² = 36
Answer:
b
