Answer:

Step-by-step explanation:

h(4) = 4^3 -2·4 = 64 -8 = 56

g(4) = 3·4 +4 = 16

Then the sum is ...

(h+g)(4) = h(4) + g(4) = 56 +16

(h+g)(4) = 72

How do you compare proportional relationships

Likurg_2 [28]

Answer: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

Really need to someone to break this down so I can understand it

djyliett [7]

Answer:

Slope is 4/3

Step-by-step explanation:

Slope is the derivative of the equation:

$y = \frac{1}{3} {x}^{2} - 2x + 15 \\ \\ \frac{dy}{dx} = \frac{1}{3} (2x) - 2 + 0 \\ \\ \frac{dy}{dx} = \frac{2}{3} x - 2$

At point (5, 7), x is 5:

$\frac{dy}{dx} = (\frac{2}{3} \times 5) - 2 \\ \\ \frac{dy}{dx} = \frac{10}{3} - 2 \\ \\ \frac{dy}{dx} = \frac{10 - 6}{3} \\ \\ \frac{dy}{dx} = \frac{4}{3}$
