If the coordinates of point E are (-4, y), what is the value of<br> у?

BlackZzzverrR [31]

Answer:

-8

Step-by-step explanation:

First we need to find the slope of CD.

We know C is (-10, -2)

and we know D is (10,6)

If we use the slope formula, we can see the slope is $m=\frac{6-(-2)}{10-(-10)}$

$m = \frac{8}{20} \\m=\frac{2}{5}$

We can see point F is at (6,-4)

We can find the equation of this line by using point slope form, and plugging in F as our point.

$y-(-4)=\frac{2}{5}(x-6)\\y=\frac{2}{5}x-\frac{32}{5}$

To find where E, we need to find the y value when x = -4

$y=\frac{2}{5}(-4)-\frac{32}{5}\\y =-8$

Round to the nearest hundredth

Charra [1.4K]

Hey there,
1st hat = x
2nd hat = 2x
3x = $75.12
x= $75.12 / 3
= $25.04
2x = $25.04 x 2
=$50.08
= $50.10 (round off)

Hope this helps ^_^

The ratio is boys to girls is 3:5. If there are 24 boys how many girls are in the class

RoseWind [281]

If the ratio is 3:5, then for every 3 boys there are 5 girls, so you multiply 3 and 5 by 24 and you get your answer.
