When x varies inversely with y then you'll have
xα1/y
x=k/y where k is the proportionality constant
when x=8. y=10. k=?
8=k/10
make k the subject of the formula
k=10×8
k=80.

When x=6. y=?.k=80
6=80/y
Make y the subject of the formula
y=80/6
y=40/3

Jessica wrote the numbers 4 1/5,3 1/3, 5 1/2 in the form of a fraction.Whats the greatest numerator that Jessica wrote?

marysya [2.9K]

The correct answer is 5 1/2 because if it weren’t simplified it would be 6/2 which makes the numerator the greatest.

Distribute ^4 to both 2 and q^5

2^4 = 2 x 2 x 2 x 2 = 16
(q^5)^4 = q^20

16(q^20) = 16q^20

16q^20 is your answer

hope this helps

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-10, -4)

Point (10, -29)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute [SF]: $m=\frac{-29+4}{10+10}$
Add: $m=\frac{-25}{20}$
Simplify: $m=\frac{5}{4}$
