Answer:
-0.5
Step-by-step explanation:

This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
Answer:
Step-by-step explanation:
to solve this you would subtract 100 from each side :
Y = 100+50x
-100 -100
-100= 50x
then you would divide each side by 50 to get 'x'
-100/50=50x/50
-2 = x
Answer:
y = 0.5x - 5.5
Step-by-step explanation:
slope = 0.5, so this is the x coefficient.
y intercept = -2 - (7 x 0.5) = -5.5
Step-by-step explanation:
-43
