8.75$ you would divide 12.50 by 10 and get 1.25 and then multiply that by 7 which would equal 8.75$
The Correct Answer is
Ex. 38+ 23=30 + 20 +8 +3=50+8+3=58+3=61.
Answer: f^ -1 = x-9/2
Explanation & Steps:
1) Change f(x) to y
2) Switch y and x -> you will get x= y + 9/2
3) subtract 9/2 on both sides -> you will get x-9/2= y
Result- y = x-9/2
(Switch y to f^-1)
Hope this helps :)
Answer:
$11.10
Step-by-step explanation:
1 small package = $2.40

2.40 + (3 × 2.90)
=2.40 + 8.70
=11.1
Answer:
P = 14.9
Step-by-step explanation:
i used distance formula:
d = √(difference of y-values, squared, + difference of x-values, squared)
distance from (-2,1) and (2,4):
= 5
distance from (-2,1) and (-1,-2): 
distance from (-1,-2) and (2,4):
= 3
P = 5 +
+ 3
≈ 14.9
