For the function y=400-22x, what is the rate of change

Mathematics
1 answer:
dolphi86 [110]3 years ago
8 0

Answer:

-22

Step-by-step explanation:

The function y=400-22x is a linear equation in the form y=mx + b. Although they put "mx" after "b" so the equation doesn't start with a negative.

"m" is rate of change, or the slope if graphed.

The negative means "y" decreases as "x" increases. On a graph, it decreases left to right.

Write each mixed number as a decimal
andriy [413]

Hey there! I'm happy to help!

If we want to turn this into a decimal, we only need to find what the fraction is as a decimal because we already know the whole number

QUESTION 1

We know that our decimal is 4 point something. We know that this something is 1/5. To turn a fraction into a decimal, you just divide the numerator by the denominator.

1÷5=0.2

We add the whole number and fraction.

4+0.2=4.2.

QUESTION 2

14÷15=0.933333 repeating

We add this to the whole number.

12.93333333 repeating.

QUESTION 3

5÷32=0.15625

We add this to the whole number.

5.15625

Have a wonderful day! :D

If m(x)=1/x+5, when m(1/2)?
blagie [28]

Answer:

The answer to your question is:  m (1/2) = 7

Step-by-step explanation:

Function                         m(x)=1/x+5

when m(1/2)

Then                             m (1/2) = 1 /(1/2) + 5         Substitution

                                    m (1/2) = 2/1 + 5              

                                    m(1/2) = 2 + 5                  Simplify

                                   m (1/2) = 7
