Answer:

-3x - 11.

Step-by-step explanation:

We replace the x in w(x) by (-4-x):

w(-4-x) = 3(-4 - x) + 1

= -12 - 3x + 1

= -3x - 11.

PSYCHO15rus [73]

For this question, you must use the Pythagorean theorem.
a^2 + b^2 = c^2

In this situation c=16 and a=6
First do 16^2. This equals 256
Second do 6^2. This equals 36

Now, subtract 36 from 256 and fond the square root.

Your answer should be 14.8

Jada had some dimes and quarters that had a total value of $12.50

zubka84 [21]

Answer:

1.She has 115 dimes because 0.10*115=11.5 0.25*4=1.00 11.5+1.00=12.5

2.She has 100 dimes because 0.10*100=10.00 and 0.25*10= 2.5 10+2.5=12.5

3.I think they don’t function because quarters are worth more than a dime.

4.he has 40 quarters because 0.25*40=10.00 0.10*25=2.5 10.00+2.5=12.5.

5.She has 38quarters because 0.25*38=9.5 0.10*30=3 9.5+3=12.5

6.Yes they can function because q=dx-12.5

The Questions:

Question 1 - 1 pts

If Jada has 4 quarters, how many dimes does she have?

Question 2 - 1 pts

If Jada has 10 quarters, how many dimes does she have?

Question 3 - 1 pts

Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with d =...) that you can use to determine the output, d, from a given input, q. If no, explain why not.

Question 4 - 1 pts

If Jada has 25 dimes, how many quarters does she have?

Question 5 - 1 pts

If Jada has 30 dimes, how many quarters does she have?

Question 6 - 1 pts

Is the number of quarters a function of the number of dimes? If yes, write a rule (that starts with q =...) that you can use to determine the output, q, from a given input, d. If no, explain why not.
