Betty's grade in science class is affected by the number of missing assignments. The table below shows the science grade percent

Angelina_Jolie [31]

Hi!

$y=-5x+95$

Plug in $15$ for $x$

$y=-5(15)+95$

Multiply $-5$ and $15$

$y=-75+95$

Add $-75$ and $95$

$y =15$

-------------------------------------------------------------------------------------------------------------

Betty's percentage is 15%.

The rate of change is the amount it changes for every missing assignment, therefore it would be -5.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile

Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where d represents the distance, that the car travels at this speed in t at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

Find the inverse of the function f (x) = 0.25x + 12.

worty [1.4K]

Answer:

g(x)=4x-48

Step-by-step explanation:

f(x)=0.25x + 12

substitute

f(x) with y

y=0.25x + 12

then replace x with y and y with x

x=0.25y + 12

swap equation

0.25y + 12 = x

0.25y = x - 12

divide both sides by 0.25

Y=4x-48
