Answer:

Given,

f(x)=x^2+6

g(x)=2x-1

Now,

g[f(x)]=g(x^2+6) since f(x)=x^2+6

=2(x^2+6)-1 since x > x^2+6

=2x^2+12-1

=2x^2+11

leva [86]

Answer:

y + 9 = 1/5(x + 8)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

Substitute the values into the equation.

y - (-9) = 1/5(x - (-8)

y + 9 = 1/5(x + 8)

Marat540 [252]

To answer the question above, evaluate the number of cookies each of them placed on a tray. The calculations are shown below,

Ronny C1 = 0.15 x 20 = 3
Celina C2 = 3
Jack C3 = 0.30 x 20 = 6
Michelle C4 = 20 - (3 + 3 + 6) = 8

From the calculation above, <em>Michelle</em> placed the most number of brownies on the tray.
