I believe he would be 70 years old. 85 years minus 15 years equals 70.
Answer:
(a)6 feet
(b)24 sections
Step-by-step explanation:
(a)We are required to find the length of the Giant Sub.
If each section is 1/3 of a foot long and there are 18 equal parts.
Length of the Giant Sub =
Length per Section X Number of Sections
= 1/3 X 18 = 6 feet
(b)If each section is 1/4 of a feet long
Length of the Giant Sub =
Length per Section X Number of Sections
6= 1/4 X Number of Sections
Number of Sections =6 X 4 =24 sections
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
Answer:7
Step-by-step explanation:
Simplifying, 6x-2x-8 = 6 + 2x
4x -8 = 6 + 2x
2x =14
x=7
Answer:
It would be the last option.
