Answer:
5x+31
Step-by-step explanation:
f(g(x))
5(x+7) -4
5x+35-4
5x+31=f(g(x))
Three multiplied by a number plus ten.
Split the room into 2 rectangles
area = 5*4 + 3*3 = 29 sq ft
So the cost is 29*8 = $232
Answer:
<h2>f(-7) = -6</h2>
Step-by-step explanation:
Put x = -7 to f(x) = 2x + 8:
f(-7) = 2(-7) + 8 = -14 + 8 = -6
It decreases
The further two objects are, the gravitational attraction decreases and the closer two objects are, the gravitational attraction increases
