Standard form for first one is

ax+by=c

6y-12=-3x

add 3x both sides

3x+6y-12=0

add 12

3x+6y=12

second one

distribute (don't forget double negative y)

10-2x+2y=3x+1

minus 3x both sides

10-5x+2y=1

minus 10 both sides

-5x+2y=-9

the equations are

3x+6y=12

-5x+2y=-9

ax+by=c

6y-12=-3x

add 3x both sides

3x+6y-12=0

add 12

3x+6y=12

**Answer:**

Number of trials are 250.

**Step-by-step explanation:**

A researcher finds 15% of all commuters in a metropolitan area take the train to work.

The researcher polls 250 people in the area to ask them whether they take the train to work or not.

We have tell the number of trials for this binomial experiment.

Researcher will do 250 trials to confirm whether they take the train work and this irrespective of their response.

The correct answer to this is:

ROTATIONS AND TRANSLATIONS

Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.

X= number of hours would it take Jason to wash the van by himself.

2x=number of hours would it take Wendy to wash the van by herserlf.

we calcaulate the fraction of work by Jason during one hour

x hours-----------------------------1 work

1 hour---------------------- fraction of work during one hour.

fraction of work during one hour=(1 hour * 1work) / x hours=1/x

we calculate the fraction of work by Wendy during one hour.

2x hours-----------------------------1 work

The second one because the formula for volume is length times width times height so for the first box if you do 4*3*2 you would get 12 which is the volume and for the second box if you take 2.5*2*5 you'd get 25 so the second box has the greater volume meaning it's more cost effective and it is the better box

For a box shown in the images, to see the more cost-effective option, one has to simply compare which of the two boxes has the large volume. This can be done by multiplying the length, width, and the height to find the volume. This is shown below:

Box A:

Volume = 2 * 3 * 4 = 24 ft^3

Box B:

Volume = 2 * 5 * 2.5 = 25 ft^3

Therefore, the second box is the more cost-effective of the two.

Box A:

Volume = 2 * 3 * 4 = 24 ft^3

Box B:

Volume = 2 * 5 * 2.5 = 25 ft^3

Therefore, the second box is the more cost-effective of the two.

**Answer:**

A) Price= 1617*Year - 3.116e+006; B) 150340$ By 2020

**Step-by-step explanation:**

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$

QUESTION POSTED AT 20/01/2020 - 12:44 PM

If it takes 8 hours for a bus with an average velocity of 65mph to travel from Amarillo to Austin then,

d = 65 (8) = 520 miles

The distance from Amarillo to Austin (or vice versa) is 520 miles.

If the function to get the distance traveled by the automobile is given by:

d(x) = 80 t

Then, the inverse variation relationship would be

d-1(x) = t = d / 80

Since d = 520

t = 520 / 80

t = 6.5 hours

It takes 6.5 hours for the automobile to complete the trip

d = 65 (8) = 520 miles

QUESTION POSTED AT 20/01/2020 - 12:38 PM

**Answer:**

Part A - 9 cm; Part B - 1836 cm²

**Step-by-step explanation:**

Part A: The volume of a triangular prism is given by the area of the base (area of the triangle) multiplied by the length of the box. To find the area of a triangle, we use the formula A = 1/2bh; this gives us

V = 1/2bhl

Using the information we have gives us

3240 = 1/2(24)(h)(30)

3240 = 360h

Divide both sides by 360:

3240/360 = 360h/360

9 = h

Part B: We are looking for the surface area of this prism.

There are two triangular sides, each with a base of 24 and a height of 9. Their areas are:

A = 1/2bh = 1/2(24)(9) = 108 sq cm each. For two of them, this makes

108(2) = 216 sq cm

There are two rectangular sides whose dimensions are 15 by 30; their areas are

A = 15(30) = 450. For two of them, this makes

450(2) = 900 sq cm.

There is one rectangular side whose dimensions are 30 by 24. Its area is

A = 30(24) = 720 sq cm.

This makes the total surface area

216+900+720 = 1836 sq cm.

To look for this missing value, simply subtract 50 to the sum of all of the known values of the 5 other colors to obtain the number of students who had picked pink polka dots. This is shown below:

50 - 4 - 9 - 11 - 9 - 3 = x

X = 14

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

5 = x or x= 5

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x
