Answer:

Answer is 5x+2

Step-by-step explanation:

$Given \: f(x) = 4x - 1 \: \: and \: \\ g(x) = x + 3 \\ f(x) + g(x) = 4x -1 + x + 3 \\ = 5x + 2$

Answer:

-3 or decreasing by 3

Step-by-step explanation:

To find the average change, you only care about the first and last point which would be (3,17) and (8,2)

the overall change during that time is 2-17=-15 (for the f(x) side )

the overall change during that time is 8-3=5(for the x side)

all we have to do is -15/5=-3

therefore the average rate of change is -3

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=83°, and RS = 7 feet. Find the length of SQ to the nearest tenth of a foot.

Simora [160]

Answer:

x ~0.9

Step-by-step explanation:

To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.

$tan(83)=\frac{7}{x}$

Manipulate the equation so that it is solved for (x),

$x=\frac{7}{tan(83)}$

x ~ 0.859
