Answer:
slope = -2
Step-by-step explanation:
y2 - y1 over x2 - x1
so do
7-3/ 2-4 = your slope
4/-2
Answer:
a,c,e,f
Step-by-step explanation:
scientific notations can only be less than 9
Answer:
Step-by-step explanation:
4*(x + 5) + 8x = 4*x + 4*5 + 8x
= 4x + 20 + 8x
= 4x + 8x + 20
= 12x + 20
Answer:
y-intercept: (0, 5)
Step-by-step explanation:
This parabola has an equation of -x² + 4x + 5.
It's y-intercept is (0, 5).
It's x-intercepts or roots are (-1, 0) and (5, 0).
It's vertex is (2, 9).
___________________________________
Keep in mind that the y-intercept is when x = 0.
