H(x) = ax^2 +1<br> Find the value of a when h(-2) = 21.
blagie [28]

Answer:

a = 5

Step-by-step explanation:

Solving h(-2) = 21:

h(-2) = 21 \\ a(-2)^2 +1 = 21 \\ a(4) +1 = 21 \\ 4a +1 = 21 \\ 4a +1 -1 = 21 -1 \\ 4a = 20 \\ \frac{4a}{4} = \frac{20}{4} \\ a = 5

I NEED HELP IM BEGGING YOU????:) Write the slope-intercept form of the equation for the line.
iogann1982 [59]
It’s d because the slope is negative and it is 2/1 which can also be written as just 2. in the formula y=mx+b, m is the slope and b is the y-intercept. the y-intercept is where the line touches the y axis(in this case -1) so it would be written as y=2x+(-1)
