15=8d+17
8d=15+17
8d=32
d=32 divided by 8
d=4

15 = 5 + 8d - 12
15 = 8d - 7
15 + 7 = 8d
22 = 8d
d = 2.75

Is the function represented by the table linear

Bess [88]

Answer:

No, because it does not have a constant rate of change.

Step-by-step explanation:

On the x side of the table, there is a constant rate of change (+1). However, on the y side, it is not. The first change is +7, the next +5, and the last +6. The rate of change has to be constant on both sides for the table to be considered linear.

Which of the following is the solution to |7x+12|=12

tamaranim1 [39]

Answer:

$x=-\frac{24}{7}\\x=0$

Step-by-step explanation:

1. You must clear the absolute value bars.

2. You have two cases: a positive case and a negative case.

3. First, you can solve the positive case as following:

$7x+12=12\\7x=12-12\\x=0$

4. Now, you must solve thie negative case as you can see below:

$-(7x+12)=12\\-7x-12=12\\-7x=24\\x=-\frac{24}{7}$

5. Therefore, the answer is:

$x=-\frac{24}{7}\\x=0$
