Answer:
odd
Step-by-step explanation:
To determine if odd/ even
• If f(x) = f(- x) then it is even
• If f(- x) = - f(x) then it is odd
Given
f(x) = 4x³ - 5x , then
f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x
Since f(x) ≠ f(- x) then it is not even
- f(x) = - (4x³ - 5x) = - 4x³ + 5x
Since f(- x) = - f(x) , then 4x³ - 5x is odd
Answer: x ≥ 1307
Explanation:
First, write the formula:
monthly fee: $14
minute rate: 7¢ or $0.07
total charge: $105.49
.07x + 14 ≥ 105.49 (the sign is this way because they said this price was the least she had been charged for a month.
You can solve for x just like you would in an equation by making the ≥ sign an equal sign
.07x + 14 = 105.49
- 14 -14
.07x = 91.49
÷ .07 ÷ .07
x = 1307 minutes
since you didn't divide by a negative number, the inequality sign stays the same:
x ≥ 1307
Answer:
yes
Step-by-step explanation:
took the same quiz got it right
I believe it’s 8^3 I’m sorry if it’s wrong!!!!
The volume of a rectangular prism is its length times width times height, or algebraically,

. You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute

into the formula for volume. You get

, and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get

. It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule

, if n is non-negative. The opposite applies so that

. For your final answer, you write

. This corresponds to
answer choice B.
