Answer:
Step-by-step explanation:
(x + 2)² = (x - 1)(x + 14)
x² + 4x + 4 = x² + 13x - 14
-9x = -18
x = 2
Answer:
8
Step-by-step explanation:
= = 8
Answer:
x = 15°
Step-by-step explanation:
165 and x are on a straight line which means they are supplementary.
Set up the equation and solve for x:
165 + x = 180
x = 180 - 165
x = 15
Answer:
y=1.5x+1; x= -0.6
y= -0.25x-6; x= -24
Step-by-step explanation:
y=1.5x+1
0=1.5x+1 (To find x-intercept/xero, substitute y=0)
-1.5x=1
x= -2/3 or x= -0.6
y= -0.25x-6
0= -0.25x-6
0.25x= -6 (Move variables to the left-hand side and change its sign)
x= -24
