Step-by-step explanation:
The slope m is a measure of the rate of change
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, - 1) ← 2 points on the line
m = [tex]\frac{-1+4}{1-0}[/tex] = [tex]\frac{3}{1}[/tex] = 3 → D

Answer: Choice A) Empty set
This is another way of saying "no solutions"
============================================
Explanation:
Your teacher made a typo. The given inequalities will have boundary lines that both have positive slopes, not negative slopes. So the boundary lines should go uphill as you move from left to right.
See the diagram below to see what the graph should look like.
The upper dashed line is y = (1/2)x+3. The lower dashed line is y = (1/2)x-2
The upper dashed line represents the boundary for y > (1/2)x+3. Region 1 is the set of solution points for y > (1/2)x+3
While the solution set for y < (1/2)x-2 is represented with region 3
There is no overlap between regions 1 and 3 due to the parallel boundary lines.
Put another way: there are no (x,y) points that are in both region 1 and region 3 at the same time.
So that's why there are no solutions to this system of inequalities.
---------------------
Alternative method:
Convert the first inequality into Ax+By > C form
y > (1/2)x+3
2y > x + 6 .... multiply both sides by 2
-x+2y > 6 ... subtract x from both sides
z > 6 .... let z = -x+2y
Convert the second inequality into Ax+By < C form
y < (1/2)x-2
2y < x - 4
-x+2y < -4
z < -4 .... let z = -x+2y
We have some number z that is both z > 6 and z < -4 at the same time, but no such number exists. So this is another way to see we have an inconsistent system with no solutions.

Answer:
x = 20
Step-by-step explanation:
The angles are same side interior angles so the add to 180
3x-10 + 5x+30 = 180
Combine like terms
8x +20 =180
Subtract 20 from each side
8x+20 -20 =180-20
8x = 160
Divide by 8
8x/8 =160/8
x = 20
Answer: x = 25
Step-by-step explanation:
When lines are parallel, the same side interior angles are supplementary, meaning they add up to 180 degrees. So to find x, you would add the two expressions and make it equal to 180 degrees.
3x - 10 + 5x + 30 = 180
8x - 20 = 180
8x = 200
x = 25
The answer is x=25

If the number is above 5, you round to the next highest number.
If the number is 4 and below, you don’t round to the next highest number.
Since 1.41 has a number below 4 that you have to round, the nearest tenth would stay 4.

Solve: −2c + 6 = 10
Answers
Explanation:
-2c + 6 = 10
-2c = 10 - 6
-2c = 4
c = 4/-2
c = -2
Answer:
i believe your answer will be C=-2
Step-by-step explanation:
the equation is -2c + 6 = 10. to solve this youll need to subtract 6 from both sides.
-2c +6 =10
-6 -6
which will now leave you with -2c = 4. then you will divide -2 from both sides. -2/-2 =0 and 4/-2 = -2. so your answer is C=-2

Answers
Given :
Zach wants to make a profit of more than 300 for painting 4 identical too rooms.
The cost of supplies is 32.50 for each room.
To Find :
Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.
Solution :
Profit is given by :
Profit = S.P - C.P
Now, it is given that profit > 300 .
Profit = S.P - C.P > 300
[tex]4n - 4\times 32.5 > 300\\\\n - 32.5 > 75\\\\n > \$107.5[/tex]
Hence, this is the required solution.

A recycling center was offering cash for different types of recyclables. For each pound of paper recycled they offered $1.41, for each pound of aluminum they offered $1.53 and for each pound of plastic they offered $0.33. Jerry took in 5 pounds of paper, 15 pounds of aluminum and 6 pounds of plastic. How much money did he earn?
Answers
Answer:
Total amount earn = $31.98
Step-by-step explanation:
Given:
Cost of paper = $1.41
Cost of aluminium = $1.53
Cost of plastic = $0.33
Amount of paper = 5 pound
Amount of aluminium = 15 pound
Amount of plastic = 6 pound
Find:
Total amount earn
Computation:
Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)
Total amount earn = $7.05 + $1.98 + $22.95
Total amount earn = $31.98

Answer:
False
Step-by-step explanation:
5x - 4 versus 2x + 26
Imagine x equals 1, then the equations would be:
5(1) - 4 and 2(1) + 26
1 and 28 are not equivalent.
Another example would be x = 6
5(6) - 4 and 2(6) + 26
26 and 38 are not equivalent.
No matter what you replace x with, the expressions are never equal.
Evaluate the following expression when a = -3, b = 2, c = 5, and
d = -4.
2a + 3b
Answers
Answer:
2a + 3b = 0
Step-by-step explanation:
So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:
2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0
So by evaluating the expression we get 0.
