9. Find the coordinates of point C along line segment AE with A(-2,-4) and
Nana76 [90]

Answer:

C = (4,-1)

Step-by-step explanation:

Given

A = (-2,-4)

E = (8,1)

AC:CE = 3:2

Required

Determine the coordinates of C

This is calculated as follows;

C = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where:

(x_1,y_1) = (-2,-4)

(x_2,y_2) = (8,1)

m:n = 3:2

So, we have:

C = (\frac{3 * 8 + 2 * -2}{3+2},\frac{3 * 1 + 2 * -4}{3+2})

C = (\frac{24 -4}{5},\frac{3-8}{5})

C = (\frac{20}{5},\frac{-5}{5})

C = (4,-1)

8-2y=3y-2<br><br> Help me please.
Ede4ka [16]
This seems like a lot more work than it is, but here we go
Simplifying<span>8 + -2y = 3y + -2
 Reorder the terms: 8 + -2y = -2 + 3y
 Solving 8 + -2y = -2 + 3y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right.
  Add '-3y' to each side of the equation. 8 + -2y + -3y = -2 + 3y + -3y Combine like terms: -2y + -3y = -5y 8 + -5y = -2 + 3y + -3y
 Combine like terms: 3y + -3y = 0 8 + -5y = -2 + 0 8 + -5y = -2 Add '-8' to each side of the equation. 8 + -8 + -5y = -2 + -8
 Combine like terms: 8 + -8 = 0 0 + -5y = -2 + -8 -5y = -2 + -8 Combine like terms: -2 + -8 = -10 -5y = -10
  Divide each side by '-5'. y = 2
 Simplifying y = 2</span>

Otto spent 3/4 of the money he had saved on a new video game. If the video game cost $48, how much money did he have before he b
quester [9]

Answer: $64

Step-by-step explanation:

Given: The part of money he spent =3/4

Let the total money Otto has be 'x'.

Then according to the question, we have

\frac{3}{4}x=48

Multiply 4 on both the sides, we get

3x=48\times4

Divide 3 on both the sides, we get

x=\frac{48\times4}{3}\\\\\Rightarrow\ x=64

Hence, the money he had  before he bought the game = $64
