$396,800

First, you want to know how many times it'll double in value. So you figure out 78/13 which you'll end up with 6.

Then you'll want to multiply 6,200*2, as that would be doubling it. You'll want to take your answer and repeat until you've done it a total of six times. Your answer should be $396,800. (Please give me Brainliest!)

Question

Complete the equation of the line through (-6,5) and (-3,-3) Use exact numbers. y=

Solution 1

The **equation **of the line **passing **through the **points **(-6,5) and (-3,-3) will be y = -(8/3)x - 11.

Let the **equation** of the line **pass **through (x₁, y₁) and (x₂, y₂).

Then the **equation **of the line is given as,

The **points **are given below.

(-6,5) and (-3,-3)

Then the **equation **of the line **passing **through the points (-6,5) and (-3,-3) will be

**Simplify **the equation, then the equation of the **line **will be

y + 3 = -(8/3)(x + 3)

y = -(8/3)x - 8 - 3

y = -(8/3)x - 11

Then the **equation **of the line **passing **through the **points **(-6,5) and (-3,-3) will be y = -(8/3)x - 11.

More about the **line passing through two points** link is given below.

Solution 2

(-6,5) and (-3,-3)

slope = (5+3)/(-6 + 3) = 8/-3 = -8/3

y = mx + b

b = y - mx

b = -3 - (-8/3)(-3)

b = -3 - 8

b = -11

equation

y = -8/3 x - 11

hope it helps

slope = (5+3)/(-6 + 3) = 8/-3 = -8/3

y = mx + b

b = y - mx

b = -3 - (-8/3)(-3)

b = -3 - 8

b = -11

equation

y = -8/3 x - 11

Question

A shipping company charges a flat rate of $7 for packages weighing five pounds or less, $15 for packages weighing more than five pounds but less than ten pounds, and $22 for packages weighing more than ten pounds. During one hour, the company had 13 packages that totaled $168. The number of packages weighing five pounds or less was three more than those weighing more than ten pounds. The system of equations below represents the situation. s+m+l=13
7s+15m+22l=168
s-l=3
Which matrix can be used to show the number of packages in the different weight classes during that hour?

Solution 1

**Answer:**

The matrix equation would be

,

and the resulting matrix is

**Step-by-step explanation:**

We first start with what is called the coefficient matrix; it contains the coefficients of the variables in the system of equations.

The coefficients of the first equation are 1, 1 and 1; this will be the first row of the matrix.

The coefficients of the second equation are 7, 15 and 22; this will be the second row of the matrix.

The coefficients of the third equation are 1, 0 and -1 (0 because there is no variable m in the equation); this will be the third row of the matrix, and gives us the coefficient matrix

The next matrix in the equation will be the variable matrix. It will contain the variables for the equation; for ours, it is s, m and l:

The last matrix in our equation will be the constant matrix, which has the values after the equals in each equation:

This gives us the equation:

To solve this, we find the inverse of the coefficient matrix and multiply it by the constant matrix:

Using a graphing calculator to perform this, we get the result

This means the small contains 6 packages; medium contains 4; and large contains 3.

Solution 2

Should be the first one with elcholen reducing form shown, and sides going 6, 4, 3. Showing packages and them being multiplied by its value of each box to eqaul 168. 6 = s 4 = m 3 = L

Question

The scatterplot shows the depth of water in swimming pools, y, based on the days after filling, x. graph What can you conclude from the graph? Check all that apply. The depth of the water in the swimming pool decreases over time. The data are clustered. There are no outliers in the data. In general, increased time does not affect the depth of the water in the swimming pool.

Solution 1

**Answer: its A,B AND C**

Question

At Martina's auto shop, it takes her 15 minutes to do an oil change and 18 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the number of tire changes she does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Martina can do in at most 3 hours ( 180 minutes).

Solution 1

Hello!

You want to know how much she can do in 180 minutes

She can do an oil change in 15 minutes

She can do a tire change in 18 minutes

Based on this information you can make the inequality

The answer is

The answer is

Hope this helps!

Solution 2

15x + 18y ≤ 180

It's at most 180 minutes so left side is 'less than or equal to 180'.

It's at most 180 minutes so left side is 'less than or equal to 180'.

Question

A survey of 1,000 people was done by New York Times. 80% of the people did not know the name of their representative in Congress. How many of the 1,000 people knew the name of the Congressman?

Solution 1

The answer is 20% of the 1000 people, as 100%-80%+20%. 1000 times 0.2 equals 200 people that knew the name.

Question

What is the exact area of a circle having the diameter of 6in A:9 pie B: 36pie C: 6 pi D: 3pie

Solution 1

Area of circle = pi r^2

r = 6/2 = 3

so

A = pi (3)^2 = 9pi

answer

A. 9 pi

r = 6/2 = 3

so

A = pi (3)^2 = 9pi

answer

A. 9 pi

Question

A pie takes 2/3 of an hour to bake if a pie is put into the oven at 7:30 at what time does it need to be taken out.

Solution 1

Convert hour to minutes:

2/3 hours = 2/3 x 60 = 40 mins

30 mins 10 mins

|-----------------------------|--------------------------------|

7.30 8.00 8.10

**Answer: 8:10**

2/3 hours = 2/3 x 60 = 40 mins

30 mins 10 mins

|-----------------------------|--------------------------------|

7.30 8.00 8.10

Solution 2

You would have to take the pie out at 8:10, because 2/3 of an hour is 40 minutes. To make the addition of time easier break it up into bits, like for here you could say, 7:30 plus 30 minutes out of the 40 is 8:00 then you could just add the extra ten minutes afterwords!

Question

How much does your employer pay into the Social Security system on your behalf? A - 4.2 percent
B - 8.4 percent
C - 6.2 percent
D - 12.4 percent

Solution 1

Workers pay an average of 6.2 percent which is 127,000 a year. But employers pay a matching amount for a combined contribution of 12.4 percent of earnings.

Meaning you are either getting**6.2** percent for being a **WORKER.**

or getting**12.4** percent for being a **EMPLOYER.**

In this question you are looking for employer**so the answer is 12.4**

** **

Meaning you are either getting

or getting

In this question you are looking for employer

Solution 2

**Answer:**

In this question you are looking for employer** so the answer is 12.4**
