Answer:
C. f⁻¹(x) = 3 - 5x
Step-by-step explanation:
To find the inverse of a function, switch x and y and solve for y.
f(x) = (3 - x)/5
Change f(x) to y.
y = (3 - x)/5
Switch x and y.
x = (3 - y)/5
Multiply both sides by 5.
5x = 3 - y
Subtract 3 from both sides.
5x - 3 = -y
Multiply both sides by -1.
-5x + 3 = y
Switch the sides.
y = -5x + 3
Change the equation.
y = 3 - 5x
Answer:
15
Step-by-step explanation:
123=x+x+12+(x+12)*3
123=5x+48
75=5x
15=x
Answer:
it is actually 70
Step-by-step explanation:
The ratio of Miko to Chiko is 5 : 12 and Chiko has 48 books so 48 /12 =4 so we are going to multiply 5 *4= 20 so Miko has 20 books
Pretty sure it’s the third one
