Answer:

- 0.4 (in decimal)

Step-by-step explanation:

Here "x" is input and "f(x)" is output

Average Rate of Change is = change in output / change in input

At x = 0, the output is 41

At x = 60, the output is 17

Average Rate of Change = (17-41)/(60-0) = -24/60 = -0.4

Hope this helps!!:):)

How do you solve this do i need to plpug in the formula

Sergeeva-Olga [200]

Answer:

B. -2, 2

Step-by-step explanation:

Apparently, we're to presume that f(x) is the line that is graphed. It has a y-intercept of +1 and a slope (rise/run) of 1/2. Its equation is ...

f(x) = 1/2x +1

If we want points of intersection, we want to solve the equation f(x) = g(x) for the values of x that make it so.

1/2x +1 = √(x +2)

Squaring both sides, we get ...

1/4x² +x + 1 = x +2

1/4x² = 1 . . . . . . . . . . . . subtract x+1 from both sides

x² -4 = 0 . . . . . . . . . . multiply by 4, subtract 4

(x -2)(x +2) = 0 . . . . factor the difference of squares

x = -2, 2 . . . . . . . . . values of x that make the factors zero

The solutions to f(x) = g(x) are x = -2 and x = 2.

Additional comment

The attached graph shows the x- and y-values at the points of intersection. The solutions to f(x) = g(x) are only the x-values, -2 and 2.

The square of (ax +b) is ...

(ax +b)² = a²x² +2abx +b²

The point-slope equation of a line is ...

y = mx + b . . . . . line with slope m and y-intercept b

If the area A of a triangle is 60sq m (square meters) and the base b is 20m (meters) what is the altitude of h

umka2103 [35]

Answer:

The altitude or height of the triangle is 6 meters.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Area of a triangle = 60 m²

Base = 20 m

2. What is the altitude (h) of the triangle?

Let's recall that the formula of the area of a triangle is:

Area = (Base * Height)/2

Replacing with the real values, we have:

60 = (20 * Height)/2

60 * 2 = (20 * Height) (Multiplying by 2 at both sides)

120 = 20 Height

Height = 120/20 = 6 meters

The altitude or height of the triangle is 6 meters.

58 = –2(m + 4) + m –22 –50 –66 –33

Anika [276]

Assignment: $\bold{Solve \ Equation: \ 58=-2\left(m+4\right)+m}$

<><><><><>

Answer: $\boxed{\bold{m=-66}}$

<><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><>

[ Step One ] Switch Sides

$\bold{-2\left(m+4\right)+m=58}$

[ Step Two ] Expand $\bold{-2\left(m+4\right)+m}$

$\bold{-m-8}$

[ Step Three ] Rewrite Equation

$\bold{-m-8=58}$

[ Step Four ] Add 8 To Both Sides

$\bold{-m-8+8=58+8}$

[ Step Five ] Simplify

$\bold{-m=66}$

[ Step Six ] Divide Both Sides By -1

$\bold{\frac{-m}{-1}=\frac{66}{-1}}$

[ Step Seven ] Simplify

$\bold{x=-66}$
