A house painting company charges $350 plus $15 per hour. Another company charges $275 plus $20 per hour. Write an equation that represents when both companies will cost the same amount. How long will the job be when both companies charge the same amount? How much will they charge?


Question 1: Write an equation.


Question 2: How long will the job be when both companies will cost the same amount?


Question 3: How much will they charge?

Answers

Answer:

BelowI hope it helps ♥

Step-by-step explanation:

1.  Equation representing when both companies will cost the same amount :

[tex]350 + 15x = 275 + 20x[/tex]

2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have;  

[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]

3. For a job that takes 15 hours , the first company will cost ;

[tex]350 + 15(15) = 575[/tex]

For a job that takes 15 hours , the second company will cost ;

[tex]275+20x\\\\275+20(15)\\\\275 +300\\\\=575[/tex]

Determine the y-intercept of the following parabola:
y = 3x2 - 12x - 5

Answers

Answer:

-5

Step-by-step explanation:

Find the y-intercept by plugging in x = 0:

  y = 3x^2 - 12x - 5

  y = 3(0^2) - 12(0) - 5

  y = 0 - 0 - 5

  y = -5

x = 50

Step-by-step explanation:

If the two angles add up to 140 then that means 40° + 2x° equals 140

Set up an equation from that evaluation and solve

40 + 2x = 140

Subtract 40 from both sides

2x = 100

Divide both sides by two

x = 50

Answer:

C. l

Step-by-step explanation:

The square root of 52 is about 7.211.

Since there is a negative sign in front of the square root, then it means that the answer is about -7.211.

On the number line you have a little bit over -7.3, a little less than -7.3 and a little more than -7.2. The closest answer would be the point that is a little more than -7.2.

How do you find the value of x with 98 & 50?

Answers

Answer:

Assuming this has something to do with the interior angles of a  triangle?

98 + 50 + x = 180, add 98 and 50.

148 + x = 180, subtract 148 from both sides.

x = 32

If A ⊂ B, then A ∩ B = A ∪ B. a) sometimes b) always c) never

Answers

The Answer is Never- Hope this helps and have a great day!

Explanation:

We are given that set  A⊂B .

This means that set A is properly contained in set B.

i.e. A≠B

This means that there are some elements in set B which are not in set A.

Now we have to show whether the following property A∩B=A∪B

always, sometimes or never hold.

As A is a proper set of B.

This means that: A∩B=A ( Since A is a smaller set)

Also, A∪B=B  (Since B is a bigger set)

                  Hence, A∩B ≠ A∪B  (Since A≠ B)

Josue knows that his aunt earns more money. than his uncle. He asked how much his aunt earns each month and was told, "$600 less than twice what your uncle earsn." If his aunt earns $4,200 per month, how much money does his uncle earn each month?

Answers

Answer:

Uncle's earnings is $2400

Step-by-step explanation:

Represent his uncle's earnings with x

$600 less than twice what your uncle earns is represented as:

[tex]2x - 600[/tex]

Since, his aunt's earnings is $4200.

We have:

[tex]2x - 600 = 4200[/tex]

Add 600 to both sides

[tex]2x - 600 + 600= 4200 + 600[/tex]

[tex]2x = 4800[/tex]

Solve for x

[tex]x = 4800/2[/tex]

[tex]x = 2400[/tex]

Hence, His uncle's earnings is $2400

what do temperature and elevation have in common

Answers

Answer: As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side. The lengths of two sides of the triangle are 13 feet and 23 feet. Find the possible lengths of the third side.

Answers

Answer:

Between the lengths of 10 and 36 (exclusive).

Step-by-step explanation:

Since the lengths of any two sides is always greater than the third, the shortest possible length of the third side must be greater than 23 when added to 13. 23-13 = 10, so the third side must be greater than 10.

However, the third side also cannot exceed the length of the sum of the other two sides. 23+13 = 36, therefore the length must be less than 36.

The possible lengths of the third side lie between 10 and 36 (exclusive).

If we use 'l' for length, this range can be represented as follows:

[tex]10 < l < 36[/tex]

What is the solution for the equation 6x - 8 = 4x? x =

Answers

Answer:

x = 4

Step-by-step explanation:

6x - 8 = 4x

subtract 4x from both sides of the equation

6x - 4x -8 = 4x - 4x

2x - 8 = 0

add 8 to both sides of the equation

2x - 8 + 8 = 0 + 8

2x = 8

divide both sides of the equation by 2

2x/2 = 8/2

x = 4

Answer:

x = 4.

Step-by-step explanation:

6x - 8 = 4x

6x - 4x - 8 = 0

6x - 4x = 8

2x = 8

x = 4.

how did you get the product of sum and differences of terms?

Answers

Answer:

Step-by-step explanation:

The the terms be x and y

The sum of the terms = x+y

Difference of terms = x-y

Product of the sun and differences will be expressed as:

(x-y)(x+y) = x²-xy+xy-y²

(x-y)(x+y) = x²-y²

Hence the product of the terms is equivalent to the difference of two squares of the terms

13%

Step-by-step explanation:

The percentage decrease is calculated by the formula below;

( new value - old value)old value * 100%

old value is 130

new value is 115

So the percentage increase will be;

(130-115)/115 * 100%

= 15/115 * 100% = 13.043%

To one decimal place, this is 13%

Decide whether or not each equation represents a proportional relationship.

Answers

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

[tex]\frac{y}{x}[/tex] = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

[tex]\frac{t}{p}=1.08[/tex]

C. Equation: [tex]x=\frac{m}{4}[/tex]

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

[tex]\frac{m}{x}=4[/tex]

D. Equation: [tex]V=12s^{2}[/tex]

This equation is NOT proportional because side length is squared, so it is not constant linearly.

Answer:

Step-by-step explanation:

A. Equation: 120 - x = L

The probability that a randomly-selected person at a show has seen the band play live before is 50%. A "superfan" is defined as someone who has seen the band play live at least 5 times. The probability that a person at a show is a "superfan" is 30%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are "superfans?"

Answers

Answer:

0.25 and 0.09

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 50%=0.50

The probability that a person at a show is a "superfan" is 30%=0.30

Two people are selected at random.

The probability that both people have both seen the band perform live before

= The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.50 x 0.50

=0.25

Similarly, the probability that both are  "superfans"

=The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.30 x 0.30

=0.09

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.25 and 0.09 respectively.

Is x = 1 a solution of the equation 2 – 8x = –6?

Answers

Let's verify by substituting 1 to x.

2 - 8x = -6

2 - 8(1) = -6

2 - 8 = -6

-6 = -6

It is equal, therefore x = 1 is the solution.

Answer:

yes

Step-by-step explanation:

Substitute x = 1 into the left side of the equation and if equal to the right side then it is a solution.

2 - 8(1) = 2 - 8 = - 6 = right side

Thus x = 1 is a solution of the equation
