Answer:
GCF is 3
Step-by-step explanation:
Given the expression -9x + 15y
First, we need to find ther individual factors
-9x = -3 *3 * x
15y = 3 * 5 * y
Since 3 is common to both factors
−9x+15y = 3(-3x+5y)
Hence the GCF is 3
Given:
Consider the below figure attached with this question.
The linear equation is:

To find:
The values to complete the table of ordered pairs for the given linear equation.
Solution:
We have,

Substituting
in the given equation, we get



So, the value for first blank is -8.
Substituting
in the given equation, we get




So, the value for second blank is 3.
Substituting
in the given equation, we get



So, the value for third blank is -4.
Therefore, the required complete table is:
x y
0 -8
3 -2
2 -4
1.) 72.75
2.)77.25
im also doing this so the guy under me can get brainliest :P
Answer:14
Step-by-step explanation:
x+y=56
x:y=5:3
Sum of ratio=5+3
Sum of ratio=8
x=5/8x56
x=(5x56) ➗ 8
x=280 ➗ 8
x=35
y=3/8x56
y=(3x56) ➗ 8
y=168 ➗ 8
y=21
x-y
35-21=14
x-y=14
