Answer:

<h2>a. The system of linear inequalities is x + y \geq 3 and 4x + 3y \leq 21.</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>

Step-by-step explanation:

Let, I will buy x pounds Blueberries and y pounds Strawberries.

I need to collect at least 3 pounds of fruits.

Hence, x + y \geq 3.

It also given that I can not spend more than $21, that is 4x + 3y \leq 21.

If I will buy 4 pound Blueberries  and 1 pound Strawberry, then x = 4 and y = 1.

Now, 4 + 1 = 5 > 3. First inequality is satisfied.

4x + 3y = 4\times4 + 3\times1 = 16 + 3 = 19 \leq 21, Second inequality is also satisfied.

Please help me find the length width and area
Lisa [10]
I would say that the length would be 2 inches, the width to be 6 feet and the area to be 144. I would say this because in order to find the area, you would need to convert 6 feet into inches. There are 12 inches in a foot. So it would be 72 inches. In order to find area you multiply the length by the width. So it would be 72 time 2, this is equal to 144. Hope this helps :)

What is the value of x?<br>a.14<br>b.17<br>c.27<br>d.34​
Oksi-84 [34.3K]
The answer is B. 17.

All this lines are there to confuse you. All you have to do is solve for x on both lines.

3x-24=x-10 subtract x from both sides
2x-24=10 add 24 to both sides
2x=34 divide both sides by 2
X=17

Hope this helps.

How do you find the average rate of change through an interval
soldier1979 [14.2K]
In order to find average rate of change over an interval, do the y2-y1/x2-x1. Solve y for x=9 and x= 4
y2 = -3(9-4)^2 + 3 = -72
y1 = -3(4-4)^2 + 3 = 3

Now, x2 matches with y2 and and x1 matches with y1 obviously...
-72 - 3/9 - 4 = -15
