18. What is the slope of the linear function associated with the sequence {12, 9, 6, 3} for x = 1, 2, 3, 4?
Aloiza [94]

Answer:

D) -3

Step-by-step explanation:

Slope of a linear function:

The slope of a linear function is the amount by which y changes when x increases by 1.

In this question:

When x = 1, y = 12

When x = 2, y = 9

When x = 3, y = 6

When x = 4, y = 3

So each time x increases by 1, y decreases by 3, which means that the slope is -3, and the answer is given by option D.

Is 0.7142857.... a rational number? why or why not?
Andreyy89
The number 0.7142857 is definitely a rational number. This number can also be expressed as 7142857/10000000. Now we know that a rational number is a number that can be expressed as a fraction or a quotient of two integers. The denominator of the fraction can never be equal to zero. In case of the number given we can clearly see that the denominator of this fraction is not zero. The actual fraction of this number is 5/7. In this case we find that the denominator is not zero.

Sal and Jen went to the store together, and each bought the same car stereo.
scZoUnD [109]

Answer: Sal used a debit card and paid a total of $324.80 for the stereo. (I took the test too)

Step-by-step explanation: Multiply $21.30 by 18 months. Then subtract the interest, $58.60, from the product because Sal paid immediately with a card which implies using a debit card. You get $324.80.
