Answer:

The Graph on the Bottom Left

Step-by-step explanation:

When a system of equations are graphed, the solution is the point that the two lines intercept.

The top left graph has a solution. The lines intercept at a point.
The top right has infinite solutions, the lines overlap.
The bottom right looks like that they intercept at the origin.

The bottom left graph has lines that do not intercept at all, so they have no solution. This would be our best answer.

Find the distance between the two points. Enter the number that goes beneath the radical symbol. (PICTURE ABOVE]

Alika [10]

For this case we have that by definition, the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have the following points:

$(x_ {1}, y_ {1}) :( 1,4)\\(x_ {2}, y_ {2}): (- 2, -3)$

Substituting we have:

$d = \sqrt {(- 2-1) ^ 2 + (- 3-4) ^ 2}\\d = \sqrt {(- 3) ^ 2 + (- 7) ^ 2}\\d = \sqrt {9 + 49}\\d = \sqrt {58}$

Thus, the distance between the points is $\sqrt {58}$

ANswer:

$d = \sqrt {58}$

A state park charges $5 per car plus $1 per person as an admission fee. The total charged for a car with x people is f(x) = x +

Studentka2010 [4]

Answer:

Given: f(x) = x + 5

If this function changes to $8 per car then

The function: f(x) = x + 8

The concept of equation of straight line: y= mx + b

where b represents the y-intercept

In the equation above, the y-intercept changed from 5 to 8.

Dan and Jake have new stamp collecting books. Dan puts 5 stamps in his book every day, and Jake puts 6 stamps in his book every

Ghella [55]

Jake puts 6 stamps in his book every day.

30/6= 5

Jake put stamps in the book for 5 days.

So, Dan puts 5 stamps in the book every day.

5*5= 25

Dan has 25 stamps when Jake has 30.

I hope this helps!

The USS Enterprise was 1,123 feet in length.

Kitty [74]

Answer:

The scale for a model that is 30 inches long is 449.2 inches.

The scale for a model that is 2 feet long is 561.5 feet.

Step-by-step explanation:

Consider the provided information.

The USS Enterprise was 1,123 feet in length.

Part (A) What is the scale for a model that is 30 inches long?

1 feet = 12 inches.

First convert the length of USS enterprise in inches.

1×1,123 feet = 12×1,123 inches

1,123 feet = 13476 inches

Divide original length with the length of model.

The scale for the model is:

$\frac{13476}{30}=449.2\ inches$

Hence, the scale for a model that is 30 inches long is 449.2 inches.

Part (B) What is the scale for a model that is 2 feet long?

Since, both the units are in feet, so simply divide original length with the length of model.

The scale for the model is:

$\frac{1123}{2}=561.5\ feet$

Hence, the scale for a model that is 2 feet long is 561.5 feet.
