Answer:
f(x)=-3x+14
Step-by-step explanation:
we have
y+1=-3(x-5)
Isolate the variable y
Distributed right side
y+1=-3x+15
Subtract 1 both sides
y=-3x+15-1
Combine like terms
y=-3x+14
Convert to function notation
Let
f(x)=y
f(x)=-3x+14

Answer:
Before going to the bakery, Lisa had more than $32.40.
Step-by-step explanation:
Hi there!
Let x be Lisa´s savings.
She brings half of her savings to the bakery and expends $14.20. What is left is more than $2.00. Then:
x/2 - 14.2 > 2
Let´s solve the inequality:
x/2 - 14.2 > 2
Add 14.2 to both sides of the inequality.
x/2 > 2 + 14.2
x/2 > 16.2
Multiply by 2 both sides of the inequality.
x > 32.4
