Answer:
Patricia is 47 years old
Sharla is 55 years old
Step-by-step explanation:
Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)
S=P+8
Rewrite the second sentence as an equation:
S+P=102
1) Substitute P+8 as Sharla in the second equation:
P+8+P=102
2) Combine alike terms:
2P+8=102
3) Subtract 8 from both sides:
2P=94
4) Divide both sides by 2:
P=47
5) Substitute 47 as P in the <u>First</u> equation:
S=47+8
6) Solve:
S=55
Number 1 is x=2.2 and number 2 is x=4.3
Answer:
The scale factor is 1/4
Step-by-step explanation:
18/72 = 10/40 = 11/44
simplify all of those and you get 1/4.
Answer:
The inverse function is 1/5x
Step-by-step explanation:
f(x) = 5x
We want to find the inverse
y = 5x
Exchange x and y
x = 5y
Solve for y
Divide by 5
1/5x = y
The inverse function is 1/5x
