Answer:
44 years old
Step-by-step explanation:
22 + 15x = 577....with x being the number of years
15x = 577 - 22
15x = 555
x = 555/15
x = 37......so in 37 years he will have them...and that would make Clark's age be (37 + 7) = 44 <===
Answer:
the extra big numbers can be written easily by the scientific notation
f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3
Answer:
$17.64
