False a rectangle could never be a square
From the equation of a line;
y=mx+c
m=2
y=2x+c
Replacing for;
y=1
x=3
1=2*3+c
1=6+c
c=1-6
c=-5
<span>y=2x-5</span>
The original price is $500.
The new price with the payment plan is $560.
The percent change equation is shown in the picture.
First we find the difference or the amount of change.
560-500= 60.
To find the percent we divide 60 (the amount of change) over 500, the original amount.
60/500= 0.12.
0.12 as a percent is 12%
The answer is B. 12%
a = - 15 and b = - 9
distribute the left side of the equation
- 15x² - 25x - 5b
for - 15x² - 25x - 5b and ax² - 25x + 45 to be equal then the coefficients of like terms must be equal, hence
- 15x² = ax² ⇒ a = - 15
- 5b = 45 ⇒ b = - 9
Answer:
(x+6)( x^2 -2)
Step-by-step explanation:
x^3 +6x^2 -2x-12
We can factor by grouping
x^3 +6x^2 -2x-12
Factor x^2 out of the first group and -2 out of the the second group
x^2 (x+6) -2 (x+6)
Now factor out (x+6)
(x+6)( x^2 -2)
