Answer:

y = 4.5x

Step-by-step explanation:

Given:

x= 2 ⇒ y=9
x=5 ⇒ y=22.5
x=8 ⇒ y=36

We can see that:

9/2 = 22.5/5 = 36/8 = 4.5

Therefore the relationship between x and y is:

y = 4.5x

Answers:
Question 19: 177 bpm
Question 20: 95˚F

Explanations:
Question 19:
You had the formula set up properly like this:
$R = \frac{885 \sqrt{25} }{25} = \frac{885(5)}{25} = \frac{4425}{25}$
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
Question 20:
You had the formula set up correctly again, and merely used the wrong sign when adding 32.
$F = \frac{9(35)}{5} + 32 = \frac{315}{5} + 32$
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F

8=56 7=42 6=30 5=20 3=?

m_a_m_a [10]

$3=6$

In this case, the pattern is the number, in this case, 3, multiplied by the number below it.

See?
$8\times7=56\\7\times6=42\\6\times5=30\\5\times4=20\\3\times2=6$

Hope this helped :)
