zloy xaker [14]

Answer:

-3x + 19

Step-by-step explanation:

f(x) = -5² - 4

f(x) = 25 - 4

f(x) = 21

(f+g)(x) = f(x) + g(x)

21 + -3x - 2

umka2103 [35]

Answer:

B

Step-by-step explanation:

- 9.2(8x - 4) + 0.7(2 + 6.3x) ← distribute parenthesis

= - 73.6x + 36.8 + 1.4 + 4.41x ← collect like terms

= -73.6x + 4.41x + 36.8 + 1.4

= - 69.19 + 38.2

Write the equation of a line for the graph:
zzz [600]

Answer: y=1/3x-2

Step-by-step explanation:

To find the equation of the line, we need the slope and y-intercept. To find the slope, we can take any two points on the graph and use the formula m=\frac{y_2-y_1}{x_2-x_1}. To find the y-intercept, we find the point that crosses the y-axis. The two points on the graph are (0,-2) and (3,-1).

m=\frac{-1-(-2)}{3-0} =\frac{1}{3}

Now, we know the slope is 1/3.

The graph crosses the y-axis at (0,-2). Therefore the y-intercept is -2. This tells us that the equation is y=1/3x-2.
