<h3>Answer: Choice A</h3>

$-8 \le x < 3 \text{ and } 4 \le x < 8$

=======================================================

Explanation:

Place your pencil on the curve. Then draw a straight vertical line either up or down until you reach the x axis. If you were to start at the left endpoint, and work your way to the right, you'll eventually shade the interval $-8 \le x < 3 \text{ and } 4 \le x < 8$ along the x axis.

We have two separate intervals being shaded in. There's a small gap from 3 to 4 that isn't shaded in.

Refer to the diagram below.

Answer:

A. y = 80x

B. g(x) = 80x

C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.

Step-by-step explanation:

Part A:

To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.

x and y remain the same in the equation.

To find m, use the slope formula with (5,465) and (7, 625).

$m=\frac{y_2-y_1}{x_2-x_1}= \frac{625-465}{7-5} =\frac{160}{2} =80$

It costs $80 a day.

The equation is y = 80x.

Part B:

Function notation replaces Y as g(x). So the equation is g(x) = 80x.

Part C:

To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.

Help please i am stuck on what to do

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

green = 3* yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

4 are yellow (10% of 40 or 40* 0.1)

12 are green (30% of 40 or 40*0.3)

14 are purple (35% of 40 or 40*0.35)

10 are grey (25% of 40 or 40*0.25 )

The sum of two consecutive integers is one less than three times the smaller integer. Find the two integers.

Minchanka [31]

The small number is 2.

The large number is 3.

<u>Step-by-step explanation:</u>

Let the two consecutive numbers be x and x+1.

x be the small integer.
x+1 be the large integer.

The sum of these two consecutive integers = small integer + large integer

The sum of these two consecutive integers is x+x+1 = (2x+1)

It is given that,

The sum of two consecutive integers is one less than three times the smaller integer.
This means that, (2x+1) is one less than three times the smaller integer.
Here, the small integer is represented as x.

<u>Therefore, it can determined that :</u>

(2x+1) = 3x-1

Keeping x term on one side and constants on other side,

3x-2x = 1+1

x = 2

Therefore, the small number is 2 and the large number is x+1 = 3.
