Answer:
Step-by-step explanation:
Given:
1. 1/5x - 1/3y = -1
2. -3/4x +1/3y = 12
Multiplying equation 1 by 15 and equation 2 by 12
3. 3x - 5y = -15
4. -9x + 4y = 144
and then Solving both equations simultaneously, since x = -20 as stated in the question and by confirmation,
Using equation 3 or 4 to solve for y,
3(-20) - 5y = -15
-5y = 60 - 15
y = 45/-5
= -9
y = -9
Answer:
n > 4
Step-by-step explanation:
Add 1 to both sides
n > 4
<u>Answer:</u>
D
of Y = (-3/2, -1)
<u>Step-by-step explanation:</u>
We are given three points on the graph:
X (4, 0)
Y (3, 2)
Z (2, 2)
and the scale factor of dilation which is 
.
Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.
Y = 
× 
, (-\frac{1}{2}[/tex] × 
Y =
