H e l p p l e a s e
BigorU [14]

Answer:

17.) 12

18.) 1/15

Step-by-step explanation:

2 ÷ \frac{1}{6}

This problem is asking how many \frac{1}{6} 's can go into 2 blocks.  If you divide one box into 6 parts, each tiny box will be \frac{1}{6} of the whole. Divide the other box into 6 parts as well, and you will get 12 of these \frac{1}{6} parts.  Check your answer by multiplying 12 by \frac{1}{6}.  The answer is \frac{12}{6} which is also equal to 2.

\frac{1}{3} ÷ 5

For this one, think of it as we have one big box divided into thirds. We want to divide each  \frac{1}{3} portion by 5. So you should have 5 tiny boxes in each \frac{1}{3} which gives you a total of 15 boxes.  But if we look at it as one big box divided into 15 parts, we know that each of those is \frac{1}{15}.  Check your answer by multiplying \frac{1}{15} by 5 and you get \frac{5}{15} which is equal to \frac{1}{3}.  

Let me know if you have any questions, and good luck!

Write a linear function f with the values f (0) =4 and f(3)=-8
Darya [45]

Answer:

Answer:

f(x) = - 4x + 4

Step-by-step explanation:

Step-by-step explanation:

A linear function has the form

f(x) = ax + b, thus

f(0) = a(0) + b = 4, that is

0 + b = 4 , hence b = 4

f(3) = 3a + b = - 8 ← substitute b = 4

3a + 4 = - 8 ( subtract 4 from both sides )

3a = - 12 ( divide both sides by 3 )

a = - 4, thus

f(x) = - 4x + 4
