A)
x^2 - 6x + c = - 5 + c
using a^2 - 2ab + b^2 = (a-b)^2
so
6x = 2 * x * 3
so
c = 9
Answer
c = 9
b)
substitute c = 9
x^2 - 6x + 9 = - 5 + 9
(x - 3)^2 = 4
Answer:
(x - 3)^2 = 4
c) solve for x
(x - 3)^2 = 4
(x - 3)^2 = 2^2
so
x - 3 = 2
x = 5
and
x - 3 = -2
x = 1
Answer: x = 1 , 3
Answer:
factors of 27?
1 and 27, -1 and -27, 3 and 9, -3 and -9,
Answer:
Number 2 is correct
Step-by-step explanation
First you multiply 5 and 0
then simplify and multiply5 and 1
5*1=5
Hope this helps
1.) slope = (y2 - y1)/(x2 - x1) = (100 - 20)/(10 - 0) = 80/10 = 8
Therefore, slope is 8; $8 is put away each week.
2.) Shifting f(x) one unit to the left will yeild f(x + 1)
3.) The reflection of f(x)=x^2+5 in the x- axis will yeild f(-x) = (-x)^2 + 5 = x^2 + 5. Therefore, g(x) = x^2 + 5
