Answer:

Step-by-step explanation:

X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.

If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.

In this case, just check if X repeats.

Adding 5% of 100, to 100 is:

Kaylis [27]

Answer:

Step-by-step explanation:

Remark

The two angles with x in their numerical value are added to get 108

Solution

10x + 2 + 4x + 8 = 108 Collect like terms

14x + 10 = 108 Subtract l0 from both sides.

14x + 10 -10 = 108 - 10 Collect like terms

14x = 98 Divide by 14

x = 98/14

x = 7

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.
