Answer:

Step-by-step explanation:
Add 7 to x gives x + 7 then divide this by 5, that is

Let n be the larger integer and n-2 be the smaller integer.
n² - (n - 2)²
= n² - (n - 2)(n - 2)
= n² - (n² - 4n - 4)
= n² - n² + 4n + 4
= 4n + 4
= 4(n + 1)
No matter what value n is, it will always be a multiple of 4.
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
Answer:
714
Step-by-step explanation:
5+2=7
7-6=1
1x4=4
Point-slope form is

where y1 and x1 are your points from the coordinate and m is the slope. So yours would look like this: y-(-4)=-3(x-(-1)) or y + 4 = -3(x + 1)
