Find the exact distance between the points (-4,0) and (-11,-12).

1 answer:

7 0

Use the distance formula:
 $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)}$ 
Plug in coordinates:
 $\sqrt{(-11-(-4))^2 + (-12-0)^2}$
[tex] \sqrt{7^2 + -12^2} [/tex]
 $\sqrt{49 + 144}$
Final answer:
 $\sqrt{193}$

When x=8 y=20. What is y when x=42?

Sergeu [11.5K]

If you would like to know what is y when x = 42, you can calculate this using the following steps:

x = 8 ... y = 20
x = 42 ... y = ?

8 * y = 20 * 42 /8
y = 20 * 42 / 8
y = 105

The correct result would be: y = 105 when x = 42.

scoray [572]

The answer to this question would be: between 8 and 10

In this question, the sports book get 9 votes but the ranges are made by twos which mean only even number will be placed on the track. The closest even number from 9 would be 8(1 number below) and 10(1 number above). So, the bar should be between 8 and 10
