Solve 5 (y + 10) = 7y

Answers

Answer:

Step-by-step explanation:

Hi there! In order to solve this equation, all you have to do is distribute the 5 to the (y+10) and then shift like terms. Once you do that, you would get 5y+50=7y, and then you subtract the 5y from the 7y in order to get the 50 by itself. That would get you 2y, and from there, you just simply divide the value of 50 by 2y- getting you to 25 as the value of y. I hope this helped! <3 (Please mark as branliest if I got this right!)

Answer:

y = 25

Step-by-step explanation:

Distribute 5 (y+ 10) to get

5y + 50 = 7y

subtract the 5y from both sides to get

50 = 2y

divide the 2 from 2y on both sides to get

25 = y, or y = 25

Hope this helps

Answer:

B) 8n - 2n - 14n

Step-by-step explanation:

What we know:

0 is our starting point.

We're going forward by 8n first, so that's the minuend. Indicate that with +8n.

We're going back twice. First by 2n, then by 14n, so those two are the subtrahends. Indicate these two as -2n and -14n respectively.

That completes the expression of 8n - 2n - 14n.

Use this information and a 5% level of significance to determine if National Applicance should reject the batch.

Answers

Complete Question

The National Appliance Company makes refrigerators. One of its suppliers, the Exeter company, produces plastic shelves for the refrigerators and ships them in large lots. The National Appliance Company requires that the percentage of the plastic shelves that are defective be no more than 10%. If more than 10% are defective, the Prime Factor Company will reject the lot. To test this, the National Appliance Company randomly selects 573 of the shelves and has them inspected. It turns out that 70 are defective. Use this information and a 5% level of significance to determine if National Appliance should reject the batch.

Answer:

The decision rule is

Reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that proportion of defective shelf is less than or equal to 0.10 hence the National Appliance Company should reject that batch of shelfs

Step-by-step explanation:

From the question we are told that

The population of defective plastics is [tex]p = 0.10[/tex]

The sample size is n = 573

The number of shelf that are defective is k = 70

The level of significance is [tex]\alpha = 0.05[/tex]

Generally the sample proportion is mathematically represented as

[tex]\^ p = \frac{k}{n}[/tex]

=> [tex]\^ p = 0.1222[/tex]

The null hypothesis is [tex]H_o : p \le 0.10[/tex]

The alternative hypothesis is [tex]H_a : p > 0.10[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^ p - p }{ \sqrt{\frac{p (1 - p)}{ n } } }[/tex]

=> [tex]z = \frac{ 0.1222 - 0.10 }{ \sqrt{\frac{0.10 (1 - 0.10 )}{ 573 } } }[/tex]

=> [tex]z = 1.77[/tex]

From the z table the area under the normal curve to the right corresponding to 1.77 is

[tex]p-value = P(Z > 1.77 ) = 0.038364[/tex]

From the question we are told that [tex]p-value < \alpha[/tex] hence

The decision rule is

Reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that proportion of defective shelf is less than or equal to 0.10 hence the company should reject theat batch of shelfs

Answers

Answer:

2,6

Step-by-step explanation:

Answer:

1. (2,6)

2. C

3. B

Step-by-step explanation:

y = - 2x + 10

y = x + 4

SInce the two equation both equal y, we can said they are equal.

- 2x + 10 = x + 4

- 10 - 10

- 2x = x - 6

- x - x

- 3x = - 6

/-3 /-3

x = 2

Then we plug the x value into the equations and we will get the point that intersects y=-2x+10 and y=x+4.

- 2(2) + 10 = 2 + 4

- 4 + 10 = 6

6 = 6

This is true since both sides are equal.

The point that intersects y=-2x+10 and y=x+4 is (2,6).

2. If the two lines y1=−12x+5 and y2=2x+5 were to be graphed, what would their intersection point represent?

C) Their intersection point is the only point where different inputs into both functions yield the same output.

Ex: y=-2x+10 and y=x+4 both have the same solution which is (2,6).

3. Given an equation y=−13x+5, explain the steps for using slope-intercept form to graph this equation.

y = - 1/3x + 5

y = - 1/3(0) + 5

y = 5

Point: (0,5)

Slope: - 1/3

Rise over run (y/x) so up 3 and left 1.

B) Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point.
