Answer: x=13
Explanation:
step 1 - multiply both sides by 6 to get rid of it
step 2 - simplify both sides
step 3 - subtract 1.4 from both sides
x = 13

Answer:
Inverse of y=x^3 is f^-1(x) = ∛x
Step-by-step explanation:
We need to find the inverse of y=x^3
Step 1:
Interchange the variables:
x= y^3
Step 2: Now solve to find the value of y
=> y^3 = x
taking cube root on both sides of the equation
∛y^3 = ∛x
y=∛x
Step 3: Replace y with f^-1(x)
f^-1(x) = ∛x
So inverse of y=x^3 is f^-1(x) = ∛x
Answer:
Front section tickets: $40
Back section tickets: $25
Step-by-step explanation:
If x is the price of back section tickets, and x + 15 is the price of front section tickets, then:
275 (x + 15) + 325 x = 19125
275 x + 4125 + 325 x = 19125
600 x = 15000
x = 25
So back section tickets are $25, meaning front section tickets are $40.
Answer:
B
Step-by-step explanation:
1) Look at the y-intercepts.
The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).
That means we can rule out both A & C.
2) Calculate the rate of change (a.k.a. slope) of f(x).
To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).
Δy / Δx = 
<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>
That means that the slope of f(x) is -3.
3) Figure out the rate of change (a.k.a. slope) of g(x).
To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.
4) The Answer
The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].
