Answer:
option 2
Step-by-step explanation:
I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.
4 years = 12 x 4 = 48 months
Option 1: 500 + 195 (48) = 500 + 9360 = 9,860
Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310
If he can wait six months, it will save him about $3,500 to go with Option 2.
70 / 14.7 = 4.8
the correct answer is 4.8
Hope I helped. =)
The answer is the second one
( b )
Associate property of addition
9514 1404 393
Answer:
(a) 1.2b
(b) 1.4h
(c) A = 1.68bh
(d) 68%
Step-by-step explanation:
(a) If 20% of b is added to b, you have ...
b + 0.20b = 1.2b
__
(b) Similarly, if 40% of h is added to h, you have ...
1.4h
__
(c) The area of the new rectangle is the product of the new dimensions:
A = (1.2b)(1.4h)
A = 1.68bh
__
(d) The original rectangle area is A = bh, so the percentage change can be computed as ...
(A'/A -1)×100% = ((1.68bh)/(bh) -1)×100% = (1.68 -1)×100% = 68%
The given increases in base and height increase the area by 68%.
ANSWER
B. The functions f(x) and g(x) because f(g(x))=g(f(x))=x
EXPLANATION
The given functions are:
and
If f(x) and g(x) are inverses, then
f(g(x))=x
Expand the parenthesis to obtain,
Also,
Hence f(x) and g(x) are inverses
