If fx()=8-10x and g(x)=5x+4, what is the value of (fg)(-2)
lyudmila [28]

So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.


g(-2)=5(-2)+4\\g(-2)=-6

So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)

f(g(-2))=f(-6)\\f(-6)=8-10(-6)\\f(-6)=8+60\\f(-6)=68

nekit [7.7K]

Answer:

$160.14

Step-by-step explanation:

15% of 174.45 = 26.16

174.45 - 26.16 = 148.28

8% of 148.28 = 11.86

Ticket Taker Tony collects 90 tickets in 5 minutes. Ticket Taker Tina collects 128 tickets in 8 minutes. Which ticket taker coll
SpyIntel [72]

Answer:

Ticket Taker Tony collects more tickets per minute.

Step-by-step explanation:

In order to find out which ticket taker collects more tickets per minute, you need to solve for how many tickets each Ticket Taker collects per minute to compare.  Since 90:5 and 128:8 are different ratios, you need to find the unit rate, or how many tickets each collects per minute.  To find unit rate, you divide the numerator by the denominator:

Ticket Taker Tony:  \frac{90 tickets}{5 minutes} = \frac{18 tickets}{1 minute}

Ticket Taker Tina:  \frac{128 tickets}{8 minutes} = \frac{16 tickets}{1 minute}

Every minute, Tony collects 18 tickets, while Tina only collects 16, so Ticket Taker Tony collects more.

Find the zeros of the polynomial x2-7​<br><br>please answer step by step
Yuki888 [10]

Answer:

x = ± \sqrt{7}

Step-by-step explanation:

To find the zeros equate the polynomial to zero, that is

x² - 7 = 0 ( add 7 to both sides )

x² = 7 ( take the square root of both sides )

x = ± \sqrt{7}

Thus the exact solutions are

x = - \sqrt{7} , x = \sqrt{7}
