A: Package A is a better deal. For example, if you get 5 car washes from each package, the results are $47 for package A and $56 for package B.
B:
Package A: 1-15, 2-1, 3-15, 4-1, 5-15, 6-1, 7-15, 8-1.
Package B: 1-28, 2-7, 3-7, 4-7, 5-7, 6-7, 7-7, 8-7.
C: Graph A represents Geometric growth and Graph B represents Arithmetic growth.
D: Package A
E: Package A
Hope this Helps! Let me know if anything is wrong!
Answer:
C -3 < x ≤ 4
Step-by-step explanation:
-9 < 4x + 3 ≤ 19.
Subtract 3 from all sides
-9-3 < 4x + 3-3 ≤ 19-3
-12 < 4x ≤ 16
Divide by 4
-12/4 < 4x/4 ≤ 16/4
-3 < x ≤ 4
F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
Answer:
15 days
Step-by-step explanation:
Total hours required =
16×5×6 = 480
Let n be the no. of days
480 = n×8×4
480 = 32n
n = 480/32
n = 15
