-12x - 18y = -48
12x -20y = -104
-38y = -152
Y = 4
-4x -6 • 4 = -16
X = -2
(X,Y) = (-2, 4) is the final answer

A girl is 18 years old and her brother is a third of her age. When the girl is 36 what would be the age of the brother?
ale4655 [162]
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old

Now when she gains another 18 years (36-18=18) he will also gain those 18 years

When she is 36 he will have 6+18=24 years old

Answer is 24.

You can see that the two angles (38° and 7) form a line or 180°. So, angle 7 and 38° must add to 180°. So, angle 7 is:
180-38 = 142

Your answer is 142°.

Step-by-step explanation:

Coordinates for the graph are ( -2,-3), (-1,-2), (0,-1), (1,0), (2,1)

The graph is the image attached to this.

How to get Y:

-2-1= -3

-1-1= -2

0-1= -1

1-1= 0

2-1= 1

Hope this helps.
