Answer:
-4x+7= -21
-4x= -21-7( this positive 7 will change to negative as we take in other side )
-4x = -28
Both the negative will be cancelled
4x = 28
x = 28/4
X = 7
therefore the X value is 7

8 costs 40 so 10 costs | 40 / 8 = ( 5*2=10) So your answer is 50 Dollars.
The answer is C
The equation has x = 8/10
To get X by itself you need to divide both sides by 8, so the equation should become X = 10/8
Vertex =(1,2). It’s is also the minimum of our parabola
Y-intercept (0,3)
Axis ps symmetry is x=1
