Answer:

x = 7

Step-by-step explanation:

Remember that the axis of symmetry (a vertical line that passes through the vertex) is exactly halfway between the two x-intercepts. Thus, the x-coordinate of the vertex is 7.

Firlakuza [10]

Answer:

Step-by-step explanation:

The rules we need to simplify this are:

$a^x*a^y=a^{x+y}$

and

$(a^x)^y=a^{xy}$

Now, let's simplify the problem:

$(y^{-7}*y^{-3})^{-1}\\(y^{-10})^{-1}\\y^{10}$

Answer choice D is y^10, so that's correct.

Michael has a substantial student debt, but he recently got a new job, which came with a signing bonus. He calculates that with

kykrilka [37]

Answer:

5000

Step-by-step explanation:

Given the question :

The size of debt after m months is respresented by the expression :

36,700 - (5000 + 500m)

Since Michael has decided to dedicate the entirety of his signing bonus towards paying his debt, then that is a constant and one-off payment.

Also, a fixed portion of his salary each month has also been assigned towards paying off his debt,

Then the amount paid from his salary after a certain number of months will be:

Fixed amount × number of months = 500 × m

Amount paid using signing bonus will be a constant = 5000

Total debt amount = 36,700

Size of debt left after m months :

Total debt - ( signing bonus - fixed amount × m)

Hence signing bonus = 5000
