Answers

Answer:

There is an infinite number of solutions.

Step-by-step explanation:

When you simplify the left side of the equation, you get -7n - 14, which is equal to the right side. If you were to plug in any number for n, it will equal the same on both sides of the equation.

Solve for n.
n+ 1 = 4(n-8)
0 n = 1
O n = 8
0 n = 11
n = 16
?

Answers

Answer:

0 n=11

Step-by-step explanation:

1. Distribute

2. Subtract 1 from both sides of the equation

+1=4−32

+1−1=4−32−1

3. Simplify

=4n−33

4. Subtract 4 from both sides of the equation

=4−33

−4=4−33−4

(4 sentences at least_

Answers

Answer:

Hi There! There are no solutions to this system.

Step-by-step explanation:

nd When graphing a set of equations, make sure that the slopes are not equivlient. If the slopes are equivlient, the lines are parallel, and parallel lines do not intersect. You can check the slope of the equations to find if they are equal. Both graphs go down by 3 each time they go over 2, making the slope -3/2. If they have the same slope, but a diffrent Y interset, they are parallel.   You can also set the equations equal to  each other, and when solving find that 7 does not equal 1, or

-3/2X+7=-3/2X+1

+3/2X

7=1

Because this is false, the lines will not intersect.

You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299. Item 6 Question 1 You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299.

Answers

Answer:

32 hours 30 min

Step-by-step explanation:

Given that your hourly pay is $9.20

say that you work for p hours, then your pay will be 9.20p

we know that p is the number of hours worked.

therefore, to earn  $299 you will need to work

299=9.20p-------1

Solving for p we have to divide both sides by 9.20

299/9.20=p

p=32.5

So you have to work 32 hours 30 min to earn $ 299

The work is doing 32 hours and 30 minutes to earn  $ 299.

Given that:

Your hourly pay is equal to $9.20

Assume that you work for p hours, then your pay will be 9.20p

Also know that p is the number of hours worked.

Therefore, to earn  $299 you will need to work

299=9.20p                   (1)

Solving for p we have to divide both sides by 9.20

299/9.20=p

p=32.5

So, to work 32 hours 30 min to earn $ 299.

Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of \$65$65dollar sign, 65 along with an hourly rate of \$28$28dollar sign, 28. The plumber only charges for a whole number of hours. Anand would like to spend no more than \$250$250dollar sign, 250, and he wonders how many hours of work he can afford. Let HHH represent the whole number of hours that the plumber works.

Answers

Answer:

Anand can afford is 6hours

Step-by-step explanation:

 Let H represent the whole number of hours that the plumber works.

given that the fixed cost is $65

and the hourly cost is $28

also given that Anand has a total of $250 with him

the total cost can be expressed in terms of the number of hours H as

250=65+28H

we can now solve for H

250-65=28H

185=28H

divide both sides by 28

H=185/28

H=6.60714285714

"The plumber only charges for a whole number of hours."

So the number of hours Anand can afford is 6hours

Answer:

Anand can afford is 6hours

185=28H

divide both sides by 28

H=185/28

H=6.60714285714

Answers

Answer: The angles are 30 30, 150, 150

Step-by-step explanation: Two lines intersect means they cross. According to the vertical angle theorem, angles that are across are the same, a line is 180 degrees so it means the angles that make up the supplementary pair add up to 180(180-30=150). So there are 2 150 degree angles and 2 30 degree angles

Answers

Given:

A local carpenter uses the function f(x) to determine the amount earned after selling x number of book cases.

[tex]f(x)=180x[/tex]

He has to sell between 5 and 10 bookcases each month in order to meet his sales goal.

To find:

The domain for this situation.  

Solution:

We have,

[tex]f(x)=180x[/tex]

where, f(x) is the amount earned be carpenter after selling x number of book cases.

Domain is the set of input values.

Here, input values are number of books he has to sell, which can be a fraction value.

Since, he has to sell between 5 and 10 bookcases each month in order to meet his sales goal, therefore the x values must be integers between 5 and 10.

Therefore, the domain for this situation is set of integers between 5 and 10, i.e., {5,6,7,8,9,10}.

Answers

Given:

Consider the below figure attached with this question.

To find:

The equation of the graph in slope-intercept form.

Solution:

From the graph it is clear that, the line passes through (0,450) and (3,350).

So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-450=\dfrac{350-450}{3-0}(x-0)[/tex]

[tex]y-450=\dfrac{-100}{3}x[/tex]

Add 450 on both sides.

[tex]y=-\dfrac{100}{3}x+450[/tex]

Step-by-step explanation:

The positive value of p from the equation is; p = 3

This is about absolute values.

We are given the equation;

10 = 43 - |7p + 12|

Let us simplify by subtracting 43 from both sides to leave the right hand side as an absolute value form.

10 - 43 = - |7p + 12|

-33 = - |7p + 12|

divide both sides by -1 to get;
