Answer:
f(x)=(x+3)^2+5
let f(x)=y
y=(x+3)^2+5
interchanging role of x and y
x=(y+3)²+5
x-5=(y+3)²
√(x-3)-3=y
y=√(x-3)-3
:.inverse of f(x)=(x+3)^2+5 is f-¹(x)=√(x-3)-3
The answer is 52 because to solve this you have to multiply 30 percent or 0.30 * 40 which equals 12 dollars then you add the 12 dollars to your 40 dollars and you get 52 dollars now that is what i call markup
I have the same question that i don’t understand sorry i’m commenting so i can see if anyone else gets that answer
Answer:
x should equal three
Step-by-step explanation:
5(x + 1) - 8 = 5x(2 - 4)
5x+1-8=5x-4
5x-7=5x-4
+7 +7
5x= 5x +3
÷ 5 ÷5
×=3
