The correct option is option B : -4 ≤ x ≤ 1

<h3>What is Increasing and decreasing function?</h3>

Increasing and decreasing functions are functions whose graphs go upwards and downwards respectively as we move towards the right-hand side of the x-axis. Increasing and decreasing functions are also called non-decreasing and non-increasing functions.

Here, from graph

as we can observe from x = -4 graph starts increases upto x = 1 and after that graph becomes constant.

Thus, between x belongs -4 to 1 the graph is increasing.

Select all that apply. In a linear function: Δy = 0 Δx = 0 Δy = n Δx = n Δy = -n Δx = -n

DENIUS [597]

Answers: All the options are right and have a special meaning.

Explanation:

1) <span>Δy = 0

Means y is constant, which is also that the slope is zero.

The function is a horizontal line (paralell to the x-axis)

2) Δx = 0

Means x is constant, the slope is not defined (∞).

The function is a vertical line (parallel to the y-axis)

3) Δy = n

Means that the change in y is constant. So, only if the change in x is also constant the slope is constant and the function is linear.

This is because the slope is Δy / Δx.

4) Δx = n

Means the change in x is constant. So, only if Δy is constant it is a linear function, for the same reason explained above

5) Δy = -n and and 6) Δx = -n

Same reasoning of 3 and 4.

Kala purchased a prepaid phone card for $30. Long distance calls cost 9 cents a minute using this card. Kala used her card only

Romashka [77]

Answer:

The call lasted 13 minutes

Step-by-step explanation:

In this question, we are told to find the number of minutes a call lasted.

The initial amount on the card is $30 and after making a phone call just once, the balance went down to $28.83

What was used would be 30 - 28.83 = $1.17 or simply 117 cents

Now these long calls come at a cost of 9 cents per minute and we have a total of 117 cents here; the number of minutes is thus 117/9 = 13

This means Kala spent 13 minutes on the call

Find the measure of each angle if c||d show work

weeeeeb [17]

Answer:

Part a) <1=72°

Part b) <2=108°

Part c) <3=72°

Part d) <4=108°

Step-by-step explanation:

step 1

Find the measure of angle 1

we know that

<1+108°=180° -----> by supplementary angles

<1=180°-108°=72°

step 2

Find the measure angle 2

we know that

<2=108° -----> by corresponding angles

step 3

Find the measure angle 3

we know that

<3=<1-----> by corresponding angles

<3=72°

step 4

Find the measure angle 4

we know that

<4=108° -----> by alternate exterior angles
