S=400+0.15c
0.15 is the slope which represents that she gets $0.15 per sale she makes.
X = 14
you set all the sides equal to 52 and combine like terms.
52=2x-7+x+3+x
52=4x-4
add 4 to each side
52+4=4x-4+4
56=4x
divide each side by 4
56/4=4x/4
14=x
Answer:
PEMDAS.
parenthesis first, then exponents, next would be mutiplication/division, then lastple add/subtract.
Step-by-step explanation:
first would be 15-7, then the 3^2, etc
(2k² + 5k - 6)(3k - 1)
(6k³ - 2k² + 15k² - 5k - 18k + 6)
6k² + 13k² - 23k + 6
Use the FOIL method to simplify the problem.
(FOIL stands for first outer, inner, last)
