Step-by-step explanation:
(n + 7)² – n²
n² + 14n + 49 – n²
14n + 49
7 (2n + 7)
7 is a factor, so for any natural n, (n + 7)² – n² is a multiple of 7.
Answer:
y = 1
Step-by-step explanation:
4 - (y-3) = 3(y+1) - 4(1 - y)
4 -y +3 = 3y + 3 - 4 + 4y
7 - y = 7y - 1
7 + 1 = 7y + y
8 = 8y
8/8 = y
Y = 2x + 1
y = 2x - 1
so the 1st one has a y int of 1 and the second one has a y int of -1...so the original line will shift down 2 units
Just multiply the denominator and the whole number then add the numerator
23/9
7/2
37/5
16/5
23/4
33/5
The answers are in order you put it in like 1-6
