Which values of x satisfy the inequality 0.5x - 0.75 _> 3.25?
a x_>5
b x_<5
c ×_<8
d ×_>8​

Answers

Answer 1

0.5x - 0.75 _> 3.25

Add 0.75 to both sides:

0.5x _> 4

Divide both sides by 0.5:

x _> 4/0.5

x_> 8

The answer is d.

Answer 2
I think the answer is 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.

Zach wants to make a profit of more than 300 for painting 4 identical too rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is 32.50 for each room. 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

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.

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.

Answers

Answer:

see below

Step-by-step explanation:

a) The unknown is the price of a large pizza

b)  Each pizza cost is positive,

c) The the price of a pizza be p,

so the price of one pizza is p

d) The expression is  

6 pizzas minus 3 dollar off each pizza

6p -3p

e) Set this equal to the total cost

6p -3p= 38.94

f) Combine like terms

3p = 38.94

Divide each side by p

3p/3 = 38.94/3

p = 12.98

The price of each pizza before discount is 12.98

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.

A recycling center was offering cash for different types of recyclables.

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

Solve: −2c + 6 = 10

Answers

Answer: c = -2

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
