Answer:

Resulting expression is - 0.8x + 4.8y +16.

Step-by-step explanation:

Given : 4(0.5x+2.5y-0.7x-1.3y+4).

To find : what is the resulting expression.

Solution : We have given that 4(0.5x+2.5y-0.7x-1.3y+4).

First we will solve the parenthesis by combine like terms:

4( 0.5x - 0.7x +2.5y -1.3y +4).

4( - 0.2x + 1.2y +4).

Now distributes 4 over parenthesis's terms

- 0.8x + 4.8y +16

Therefore, Resulting expression is - 0.8x + 4.8y +16.

Find f(g(-4)) and g(f(-4)) using the functions below.<br><br> f(x) = 2x + 7<br> g(x) = x2 + 3x - 1

daser333 [38]

Answer:

f(g(-4)) = 13.

g(f(-4)) = -3.

Step-by-step explanation:

g(-4) = (-4)^2 + 3(-4) - 1

= 3.

so f(g(-4))

= f(3)

= 2(3) + 7

= 13.

f(-4) = 2(-4) + 7

= -1.

so g (f(-4))

= g(-1)

= (-1)^2 - 3 - 1

= -3.
