A) (f+g)(x)=f(x)+g(x)=(4x-5)+(3x+9)=7x+4
B) (f*g)(x)=f(x)*g(x)=(4x-5)(3x+9)=12x^2+21x-45
C) f(g(x)) = 4(3x+9)-5 = 12x+31

Solve for x.<br><br> x=<br><br> Look at image
postnew [5]

Answer:

x = 14

Step-by-step explanation:

To find x, the following equation is generated given the available information:

\frac{(x + 7) + x)}{x + 7} = \frac{12 + 8}{12}

\frac{2x + 7}{x + 7} = \frac{20}{12}

\frac{2x + 7}{x + 7} = \frac{5}{3}

Cross multiply

3(2x + 7) = 5(x + 7)

6x + 21 = 5x + 35

Collect like terms

6x - 5x = - 21 + 35

x = - 21 + 35

x = 14

mixas84 [53]

Answer:

1. Below 2. B. d = 8h

Step-by-step explanation:

The graph is a bit confusing. But basically, substitute x for the numbers they give you.

5x

5 · 1 = 5 = y

5 · 2 = 10 = y

5 · 3 = 15 = y

5 · 4 = 20 = y

7x

7 · 1 = 7 = y

7 · 2 = 14 = y

7 · 3 = 21 = y

7 · 4 = 28 = y

Step-by-step explanation:

x-intercept is where the line crosses the x-axis

y-intercept is where the line crosses the y-axis

From inspection of the graph,

x-intercept = (-3, 0)

y-intercept = (0, 2)
