y+2>9
-2 on both sides
y>7
-y+3<8
-3 on both sides
-y<5
y is still negative so simply divide both sides by -1
y>-5
The inequality y > 7 represents the solution set of the given compound inequality.
What is inequality?
Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is the following compound inequality.
- y + 3 < 8 and y + 2 > 9
We have -
- y + 3 < 8 and y + 2 > 9
Now, first we will solve inequality (1)
- y + 3 < 8
- y + 3 < 8
- y + 3 - 3 < 8 - 3
- y < 5
y > 5
Solving inequality (2)
y + 2 > 9
y + 2 - 2 > 9 - 2
y > 7
We have two possible solution sets -
y > 5 and y > 7
To satisfy both the solution sets, the inequality y > 7 will be the final solution of the given compound inequality.
Therefore, the inequality y > 7 represents the solution of the given compound inequality.

Suppose you can buy garden fencing in lengths of 50 feet at the local hardware store. A. If you bought 100 feet of fencing and wish to enclose a rectangular garden in your backyard, what should be the dimensions of your garden in order to maximize area?
Answer:
The answer is below
Step-by-step explanation:
Let the length of the rectangular area be L and W be the width of the rectangular garden hence:
Perimeter = 2(L + W)
There is 100 feet of fencing available which represents the perimeter, therefore:
100 = 2(L + W)
L + W = 100/2
L + W = 50
L = 50 - W
The area (A) = L × W
A = L × W
A = (50 - W) × W
A = 50W - W²
To get maximum area, we find the first derivative of the area and equate to zero
A' = 50 - 2W
50 - 2W = 0
2W = 50
W = 50/2
W = 25 feet
100 = 2(L + W)
50 = L + W
L = 50 - W = 50 - 25
L = 25 feet
To maximize area, the length and width should be 25 feet each
a bricklayer stacks bricks in 2 rows with 10 bricks each in each row on top of each row there is a stack of 6 bricks how many bricks are there in total
Let me see.
Row 1 = 10 bricks
Row 2 = 10 bricks
On top of each row there are 6 bricks.
Two rows times 6 bricks per row is 12 bricks.
Total = 20 + 12 or 32 bricks.

Which angle has a measure equal to the sum
of m_SQR and mzQRS?
O ZRSC
O LSRE
O ZDQS
O ZQSR
Answer:< RSC
Step-by-step explanation:
The angle has a measure equal to the sum of m <SQR and m <QRS is
m <RSC.
The correct option is A.
We have the information from which we can write
<SQR and < QRS are two interior angles of triangle QRS
Then, m<QSR = 180 - (sum of other 2 angles)
m<QSR = 180 - (m<SQR + m<QRS) (Angle sum property)
Also, m<RSC = 180 - m<QSR
Then <RSC = (m<SQR + m<QRS)
Thus, the ideal solution is A.

Solve the inequality: -7y - 3x < 21
Answer:
x> -7/3y -7
Step-by-step explanation: -7y-3x<21
Step 1: Add 7y to both sides.
−3x−7y+7y<21+7y
−3x<7y+21
Step 2: Divide both sides by -3.
-3x/-3 < 7y+21/-3
x>-7/3y -7
for a small party of 12 people, the caterer offered a choice of a steak dinner for $12:00 per or a chicken dinner for $10.50 the final cost for the meals was 138:00. how many of each was ordered?
Answer:
let the $12 dish be x and the other y
x + y = 12 <--- 1
12x + 10.50y= 138 <--- 2
multiply equation 1 by 12
so now we have
12x + 12y = 144
12x + 10.50y = 138
now subtract each one and that cancels out x
1.5y = 6
y = 4
now subsitute that into any equation
x + 4 = 12
x = 12 - 4
x = 8

In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs. Which relation does not represent a function? * A) { (-2, -3), (1, 3), (3, -3), (5, 3) } B) { (-1, -5), (2, 4), (3, 7), (4, 10) } C) { (-2, 3), (1, 3), (3, 3), (5, 3) } D) { (3, 4), (4, 5), (3, -4), (4, -5) }
Given:
In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs.
To find:
The relation which does not represent a function.
Solution:
A relation is a function if there exist a unique output for each input.
In options A, B and C, we get unique output for each input.
In option D, we get two outputs y=4 and y=-4 for input x=3.
Since, there exist more than one output values for a single input value, therefore it is not a function.
Therefore, the correct option is D.

If you subtract 13 from my number and multiply the difference by -2 , the result is -44." What is 's number
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = [tex]\frac{-70}{-2}[/tex]
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44
