I need help with this

Answer:

Step-by-step explanation:

1) 6x + 2y = -4

         2y  = -6x - 4

           [tex]y = \frac{-6x}{2} - \frac{4}{2}[/tex]

 Ans: y = -3x - 2

2) [tex]y - y_{1} = (\frac{y_{2}-y_{1}}{x_{2}-x_{1}})(x - x_{1})[/tex]

3) y - y1 = m(x - x1)

4) y = mx + b

The answer is "Yes", the estimate done by Coley is reasonable, it will take  5 days to paint 5 rooms.

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

A painter painted about a sixth of a room in a sixth of a day. It means that 1/6 room is painted in 1/6 of the day so, a whole room is painted in 1 day itself.

So, the time to paint 5 rooms will take 5 days.

Answer:

9[tex]x^{2}[/tex]

Step-by-step explanation:

The area of a parallelogram is equal to the base times the height.

The base is 3x and the height is also 3x so the area will equal

3x × 3x

When you multiply variables you multiply the coefficients and add the exponents so when you multiply 3x and 3x you multiply 3 and 3 and the exponents 1 and 1 so you get 9[tex]x^{2}[/tex]  

Answer: 42 feet below the sea level

Step-by-step explanation: To solve for the depth, simply just plug in 6 into the equation by substituting "m" since the variable represents minutes, and the submarine has been traveling for 6 minutes.

f(6) = -120 + 13(6)

f(6) = -120 + 78

f(6) = -42

When solved,  the answer is 42.

Answer:

A = 2167.73 cm²

Step-by-step explanation:

Given that,

A trailer ramp is in the shape of a triangular prism.

the height of the ramp, h = 14 inches

The volume of the ramp, V = 4704 inches²

We need to find the area of the base of the trailer ramp.

The volume of the triangular prism is given by :

[tex]V=A\times h[/tex]

A is area of base and h is height

[tex]A=\dfrac{V}{h}\\\\A=\dfrac{4704}{14}\\\\A=336\ \text{inches}^2[/tex]

or

A = 2167.73 cm²

So, the area of the base of the ramp is 2167.73 cm².

Answer:

Rate for 100 miles = $ 6 / miles

Rate for 250 miles = $ 3.3 / miles

Step-by-step explanation:

Given that cost for covering 100 miles by flight is $600.

As rate is the cost of covering unit distance (in miles).

So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.

Similarly, the cost of covering 250 miles by flight is $825.

So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.

Answer:

The value of the missing digit is 6.

Step-by-step explanation:

When a number is divisible by 9, the sum of the digits must be 9 or a multiple of 9.

Given digits = 6785∆4

the sum of the digits = 30 + ∆

30 + ∆ = 36

∆ = 36 - 30

∆ = 6

Thus, the value of the missing digit is 6.

There is four 1/4's per mile.

This means you run 1 mile in 3 x 4 = 12 minutes.

Multiple minutes per mile by total miles:

12 minutes per mile x 26.2 miles = 314.4 minutes.

1 hour = 60 minutes:

Divide total minutes by 60 to get hours:

314.4 minutes / 60 minutes per hour = 5.24 hours.

Multiply the decimal part of the hour by 60 to get the minutes:

0.24 x 60 = 14.4 minutes = 14 minutes and 24 seconds.

Total time = 5 hours, 14 minutes and 24 seconds.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

You have to keep in mind that the opposite side length depends on the size of the angle. If you are comparing side lengths, the smaller side length will have a smaller corresponding angle. That being said angle J needs to be smaller than 82, and larger than 0.

Use algebra to determine that x has to be greater than 3 in order to be above 0. X also has to be less than 44 in order to be less than 82.

Answer:

If you want to solve for x, then it is x=3+y

If you want to solve for y, then it is y=x-3

Step-by-step explanation:

You want to isolate the variable you are solving for. If you are solving for x, you don't have to isolate it because it is already on its own side. You only have to divide by 3 to take away the 3 from the x but make sure do whatever you do on one side to the other side to make sure its still equal. After you divide 3 on both sides, you end with x=3+y.
