Answer:
D. (3x - 8) (8x + 5)
Step-by-step explanation:
<em><u>To factor this trinomial, you must split the middle term into two terms, like so:</u></em>
<em><u /></em>
<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
3x(8x + 5) -8(8x + 5)
(3x - 8) (8x + 5)
Answer:
C
Step-by-step explanation:
By the definition of an inverse function, if:
Therefore, the domain of the original function will be the range of the inverse function.
And the range of the original function will be the domain of the inverse function.
We have the original function:
With the domain:
Since the domain of the original function is such, then the range of the inverse function is also the same as above.
So, the range of the inverse function is also:
So, our answer is
C.
Notes:
A, B, and E would automatically be incorrect since we never use ”or equal to” when using the infinity symbol. This is because we can never “equal” infinity.
We have to find the equation for three times a number is three more than twice the number.
Let the number is x.
Three times a number = 3x
Three more than twice the number. = 3+2x
These two equations should be equal.
Hence, we have
Therefore, the equation 3x = 3 + 2x can be used to find the unknown x.
A is the correct option.
