Answer:
Hope it helps!
Step-by-step explanation:
The general form of a cubic function is y = ax3 + bx + cx + d where a , b, c and d are real numbers and a is not zero. We can graph cubic functions by plotting points.
A cubic function is any function of the form y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants, and a is not equal to zero, or a polynomial functions with the highest exponent equal to 3. These types of functions are extremely prevalent in applications involving volume.

Answer :C
Step-by-step explanation: Lets begin with making this into an equation where x is the amount of months
x must be bigger than zero for them to cross
Power Plus = 34.06x + 20
Heavy Hulk = 34.31x + 32.50
When are these equal
34.06x + 20 = 34.31x + 32.50
34.06x = 34.31x + 12.50
-0.25x = 12.50
x = -50
Since x must be higher than zero(you cant go there for minus months) the answer is C
LAST ONE and if you solve it it will be 90
Answer:
<u>1. The number is 71.3</u>
<u>2. The number is 127.1</u>
<u>3. The number is 230</u>
<u>4. The number is 34</u>
Step-by-step explanation:
Let's find out the numbers, x, for each case:
1. 5% of it is 5% of it is 23% of 15.5
5% = 0.05
23% of 15.5 = 0.23 * 15.5 = 3.565
Then, we have:
0.05x = 3.565
x = 3.565/0.05
x = 71.3
<u>The number is 71.3</u>
2. 4% of it is 31% of 16.4
4% = 0.04
31% of 16.4 = 0.31 * 16.4 = 5.084
Then, we have:
0.04x = 5.084
x = 5.084/0.04
x = 127.1
<u>The number is 127.1</u>
3. 4.5% of it is 23% of 45
4.5% = 0.045
23% of 45 = 0.23 * 45 = 10.35
Then, we have:
0.045x = 10.35
x = 10.35/0.045
x = 230
<u>The number is 230</u>
4. 5.5% of it is 17% of 11
5.5% = 0.055
17% of 11 = 0.17 * 11 = 1.87
Then, we have:
0.055x = 1.87
x = 1.87/0.055
x = 34
<u>The number is 34</u>
