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:
B. subtract 12 from both sides
Step-by-step explanation:
12-4x=54
<u>-12 -12</u>
<u>-</u><u>4</u><u>x</u><u>=</u><u>4</u><u>2</u>
17.154 < 17.15 is incorrect.
17.15 is 17.150 which is less than 17.154 not greater than.
Answer:
8
Step-by-step explanation:
4(5) - 6 = 14
14 is not larger than 22, so 5 is not the solution.
4(8) - 6 = 26
26 is larger than 22, so 8 is the solution
