15 0/0
Step-by-step explanation:
15 cubes on each side which totals to 30 cubes. To get the volume 15 cm multiply 30 x 1/2 = 15 the amount of volume
Answer:
(- 8, - 17 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 7 → (1)
y = x - 9 → (2)
Substitute y = 3x + 7 into (2)
3x + 7 = x - 9 ( subtract x from both sides )
2x + 7 = - 9 ( subtract 7 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8
Substitute x = - 8 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = - 8 - 9 = - 17
Solution is (- 8, - 17 )
Answer:

Step-by-step explanation:
In order to find the inverse of a function, we need to follow a couple of steps.
- Step 1: Write the function as
- Step 2: Swap all x and y values
- Step 3: Solve for y
- Step 4: Replace y with
We can follow these steps to find the inverse of this function.
Step 1: We can just replace the f(x) with y, making our function
.
Step 2: We can swap where the x and y values are, making our equation

Step 3: We can now solve for y.
We now have the function as
.
Step 4: We can now replace the y with
.

Therefore the inverse of
is
.
