Which graph represents the equation -5x+4y>-1?

Answers

Answer: Choice D

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

Explanation:

The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.

A solid boundary line means that points on the boundary are part of the solution set.

Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.

[tex]-5x + 4y \ge -1 \\\\-5(4) + 4(0) \ge -1 \\\\-20 \ge -1 \\\\[/tex]

This is false because -20 is not larger than -1. It's the other way around.

This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.

The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.

Answer:

.6 is more than 1/2

.34 is less than 1/2

.812 is more

.9 is more

.099 is less

Step-by-step explanation:

1/2 as a decimal is .5 so anything larger than it will be .51 or greater and anything less will be .49 or less

Answer:

.6 is more than 1/2

.34 is less than 1/2

.812 is more than 1/2

.9 is more than 1/2

0.99 is more than 1/2

Step-by-step explanation: What is 1/2? 0.5. Look at the tenths place. Is the tenth higher than 5 or less than 5? But here is a warning: If you are comparing 1/2 and 1.4, 1.4 is greater than 1/2 because 1/2 is less than 1.

Container A and Container B have leaks. Container A has 800 ml of water, and is leaking 6 mil per minute. Container B has 1,000 ml, and is leaking 10 mil per minute. Write and equation that would show how many minutes, m, it take for the two containers to have the same amount of water.

Answers

Answer:

50 minutes (I think)

Step-by-step explanation:

A= 800 - 6m

B = 1000 - 10m

800 - 6m = 1000 - 10m

4m = 200

50 = m

The third is one-half as long as the second. How long is the second piece?

Answers

Answer:

64in

Step-by-step explanation:

first =2* second

second=2*third since the third is half of second

first =2*2*third=4*third

now lets put them all together

first+second+third=224

4*third+2*third+third=224

7*third=224 so the third part is 32

Graphs aren't mandatory, but they may help visual learners see why an equation works a certain way. Also, they are a visual tool to quickly find a solution to a problem. Furthermore, they help with presentations to quickly convey an idea to someone (who may not be well versed in mathematics).

For example, if you save $10 a week and already have $50 in a savings account, then the equation you graph is y = 10x+50. Here x is the number of weeks and y is the amount saved.

Now let's say you want to find out how many weeks it would take to have $90 total. You could use guess and check to get the answer. Or you could use algebra and the substitution property. The visual way would be to graph y = 10x+50 and y = 90 together to note how the two lines intersect at (4, 90) to indicate it will take x = 4 weeks to have y = 90 total.

Keeley ordered 240 T-shirts to sell at the school carnival. She paid $3.20
per shirt, plus 5% of the total order for shipping. When she sells each T-
shirt at the carnival, she adds a 150% markup to the total price she paid for
the shirt (including the cost of shipping). What is the selling price of each T-
shirt?

Answers

Answer:

We have 200 shirts

Cost $2.80 each

plus a 5% charge for shipping.

Selling price

150% markup

Recall when we use percentages, we need to express them as decimals.

Michelle's cost for each shirt was

2.80 (1.05) = 2.94

The markup is

2.94 (1.50) = 4.41

The markup is added to the cost to get the final selling price.

2.94 + 4.41 = $7.35

Michelle will sell each shirt for $7.35.

Let’s reword the question to make it simpler to understand:

Keeley pays $3.20 per shirt + 5% for shipping.

She sells them at the carnival for 150% the price she paid.

First of all we should work out how much the 5% shipping cost Keeley.

If the shirts are $3.20 that means 10% is $0.32, to get 5% we divide that by 2. This means 5% is $0.16, therefore shipping is $0.16.

The total price Keeley pays per shirt is $3.20 + $0.16 = $3.36.

Now let’s find out 10% of $3.36, which is $0.336, then multiply that by 15 to get 150%:

5.04

Therefore Keeley sells each shirt for $5.04

HELP ASAP PLEASE

Answers

Answer:    4x - y = 20

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

Work Shown:

y = 4x - 20

4x - 20 = y ...... swap both sides

4x = y + 20 ..... adding 20 to both sides

4x - y = 20 .... subtracting y from both sides

The equation is now in standard form (Ax+By = C) where,

A = 4B = -1C = 20
