Use the graph to determine the domain and range of the relation, and whether the relation is a function. a.
Domain: {x| -8, 8}; Range: all real numbers: No, it is not a function.
b. Domain: {xl -8 X < 8}; Range: all real numbers: Yes, it is a function.
c. Domain: {x] -8 < x < 8}; Range: all real numbers; No, it is not a function.
d. Domain: {xl -8 sx s 8}; Range: {yl -12 sx s 12}; Yes, it is a function.

step-by-step explanation:

14 x 3 = 42

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
