Answer:
Step-by-step explanation:
To find the inverse of a function you must first swap the places of x and y
Now solve for y
Step 1: Flip the equation.
Step 2: Subtract 9 from both sides.
Answer:
C = 97.20
Step-by-step explanation:
Given that C varies as r² then the equation relating them is
C = kr² ← k is the constant of variation
To find k use the condition C = 202.80 when r = 2.6
k = = = 30
C = 30r² ← equation of variation
When r = 1.8, then
C = 30 × 1.8² = 97.20
Answer:
x = 3
y = -1
Step-by-step explanation:
Finding X
Substitute y into the 1st equation
3x + 2(x-8) = 7
Simplify
3x + 2x-8 = 7
Combine like terms
5x - 8 = 7
Move the constant (-8) to the right
5x = 7+ 8
Simplify
5x = 15
Divide both sides by 5
x = 3
Finding Y
Now since you know x is 3 substitute that into the 2nd equation
y = 3 - 4
y = -1
Answer:
4
Step-by-step explanation:
To solve this problem let us first find , or find <u>the function of f(x) in terms of g(x)</u>. All we have to do is replace <em>x</em> with g(x) in the function f(x):
We have to find the the degree of , which is the largest exponent on one of the polynomial's terms. Notice that has the greatest exponent of 4.
<u>Therefore, the degree of (fog)(x) is 4.</u>

You should not calculate the routines but instead you should calculates how much it is front and center.
