The rule for Function A is y= -2/3x
Rom4ik [11]

Answer:

Both functions have negative rates of change

Function B has a greater rate of change than Function A

Step-by-step explanation:

we know that

<em>Function A</em>

The rule for Function A is

y=-\frac{2}{3}x

This is the equation of a proportional relationship (the line passes through the origin)

The slope is equal to m=-\frac{2}{3}

<em>Function B</em>

Find the equation of the function B

we have the points (-2,0) and (0,-2)

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-2-0}{0+2}

m=\frac{-2}{2}

m=-1

The equation of the function B in slope intercept form is equal to

y=mx+b

we have

m=-1\\b=-2

substitute

y=-x-2

<u><em>Verify each statement</em></u>

Option 1) Both functions have negative rates of change

The statement is true

Because, the rate of change is the slope of the linear equation

Function A ----> m=-\frac{2}{3}

Function B ----> m=-1

Option 2) Both functions have the same rate of change.

The statement is false (see the explanation)

The rate of change are different ( m=-2/3 and m=-1)

Option 3) When graphed, Function A and Function B are parallel

The statement is false

When graphed, Function A and Function B are intersecting lines, because their slopes are different

Option 4) Function B has a greater rate of change than Function A

The statement is true

Remember that the rate of change can be either positive (increasing function) or negative (decreasing function). To find out which function has a greater rate of change, compare the absolute value of their slopes

therefore

1 > 2/3

I'm not sure, but what I got was -8.5, since it is only stating that it is -17 and 5, and you need to figure out Point B, when it is between A and 0. So, you don't pay attention to 1-5. You only want -17 through 0. -17 divided by two would be -8.5

The recipe made eight servings but I only want to make a note for five people if the recipe for eight servings call for 2 cups o
Hunter-Best [27]
8 / 2 = 45 / x....8 servings to 2 cups = 45 servings to x cups
cross multiply
(8)(x) = (2)(45)
8x = 90
x = 90/8
x = 11 1/4 (or 11.25) cups of flour are needed <==

1. The sum of the angles is 90° The difference between twice the larger angle and the smaller
Ostrovityanka [42]

Answer:

\displaystyle 25°\:and\:°65

Step-by-step explanation:

{90° = m∠1 + m∠2

{105° = 2m∠1 - m∠2

_______________

\displaystyle \frac{195°}{3} = \frac{3m∠1}{3} \\ \\ 65° = m∠1

All you have left to do is this:

\displaystyle 25° = -65° + 90°

So, your two angle measures are \displaystyle 25°\:and\:°65.

I am joyous to assist you anytime.
