Solve the equation -14+2b+= -2b+2

disa [49]

Answer:

b=4

Step-by-step explanation:

-14+2b= -2b+2

Add 2b to each side

-14+2b+2b= -2b+2b+2

-14+4b =2

Add 14 to each side

-14+4b+14= 14+2

4b = 16

Divide each side by 4

4b/4 = 16/4

b =4

For which interval is the function increasing Choose two answers that are correct

kaheart [24]

Answer:

-8 ≤ x ≤ - 6

2 ≤ x ≤ 6

Step-by-step explanation:

Increasing part of the function can be easily determined from the graph.

Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.

From the graph, we see that the function is increasing in the interval $- 8 \leq \ x \leq -6$

Between -6 and -4, the graph is constant and takes the value 4.

After that it decreases till x = -2 until it becomes a constant function again on x = 2.

Then, it again increases from x = 2 till x = 6. This is represented by the interval

$2 \leq x \leq 6$ .

Then it again decreases.

So, OPTION A and C are the answers.
