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.
1. <u>Correct</u>
2. <u>Incorrect</u>, answer is x ≤ -4.25 This is because the line goes to the left so it is less than or equal to.
3. <u>Incorrect</u>, the answer is the choice at the top, because it is greater than, it goes to the right and has a empty circle.
4. <u>Incorrect</u>, the answer is the choice at the bottom cuz it is greater than or equal to so the line goes to the right and the circle is filled in.
Hope that helps u!!
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.
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.
