what’s the answer to this question? i’ve been having a hard time figuring it out

The equations are two parallel lines, then the system of equations has no solutions.

Here we have a system of equations:

-7x + 7y = 1

2x - 2y = -18

Now, if we multiply the second equation by (7/2) we will get:

(7/2)*(2x - 2y) = -18*7/2

7x - 7y = -63

If we multiply this by -1 we will get:

-1*(7x - 7y) = -1*-63

-7x + 7y = 63

Then the system of equations becomes:

-7x + 7y = 1

-7x + 7y = 63

Notice that the left side is equal in both equations but the right side is different, then the system has no solutions.

The rate of change in the given graph is 21/4.

The rate of change defines the speed of a variable changes over another variable. On the given graph, we can calculate the rate of change using the formula:

Rate of change = Δy / Δx

To calculate the rate of change of the given graph, we need to identify 2 points first. We take:

(0, 0)

(4, 21)

Rate of change = Δy / Δx

Rate of change = y₂ - y₁

                             x₂ - x₁

Rate of change = 21 - 0

Area = 5 units^2

Step-by-step explanation:

Graph three points to make a triangle.

Use

Area = 1/2•b•h

to find the area.

Fortunately, the base is horizontal and the height is vertical, so we can just count the squares to find those lengths. (If they aren't horizontal and vertical, then you need distance formulas)

True. The variables x, y, and z have each been assigned an integer value.

Here is a fragment of code that assigns the least of three integer variables to another variable named min:

min = x  # initialize min to the value of x

if y < min:  # check if y is less than min

   [tex]min = y[/tex] # [tex]update min to the value of y if y is less than min[/tex]

if z < min:  # check if z is less than min

   [tex]min = z[/tex] # [tex]update min to the value of z if z is less than min[/tex]

In this code, the variable 'min' is first initialized to the value of 'x'. Then, the code checks if 'y' is less than 'min', and if so, updates the value of 'min' to 'y'. Finally, the code checks if 'z' is less than 'min', and if so, updates the value of 'min' to 'z'. At the end of this code fragment, the variable 'min' will contain the least of the three variables 'x', 'y', and 'z'.

The length and width of the rectangular board is 27 inches and 23 inches respectively

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the mat be = 184 inches²

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Let the area of the larger rectangle be = ( 2x - 3 ) ( x + 8 )

Let the area of the smaller rectangle be = ( 2x - 7 ) ( x + 4 )

Now , the area of mat = area of the larger rectangle - area of the smaller rectangle

So , 184 = ( 2x - 3 ) ( x + 8 ) - ( 2x - 7 ) ( x + 4 )

On simplifying the equation , we get

2x² - 3x + 16x - 24 - [ 2x² + x - 28 ] = 184

On further simplification , we get

12x + 4 = 184

Subtracting 4 on both sides of the equation , we get

12x = 180

Divide by 12 on both sides of the equation , we get

x = 15

So , the length of the board = ( 2x - 3 ) = 27 inches

And , width of the board = ( x + 8 ) = 23 inches

Hence , the dimensions of the rectangular board is 27 x 23 inches²

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, The ratio of flour to eggs in a pancake recipe is constant.

The pancake recipe uses 5 cups of flour for each egg.

Since,

With one egg we need a total number of cups of flour = 5

Thus,

For 2 eggs, we need a total number of cups of flour = 5*2

For 2 eggs, we need a total number of cups of flour = 10

For 5 eggs, we need a total number of cups of flour = 5*5

A population is divided into many clusters that are representative of homogenous traits and have an equal probability of being included in the sample using the sampling technique known as cluster sampling.

Using this sampling approach, researchers examine a sample that includes a variety of sample criteria, including demographics, lifestyle, background, or any other population characteristic that may be the subject of the research being done. This approach is typically used when a statistical population is made up of comparable but internally heterogeneous groupings.

The statement that describes the relationship is: option B.

The situation that can be represented by the equation y = 12x is: B. "Yvonne has y dollars. This is one half more dollars than her friend Marie who has x dollars."

In the equation y = 13x, y is equal to 13 times x. This means that y increases by a factor of 13 for every increase in x.

In the equation y = x + 13, y is equal to x plus 13. This means that y is always 13 more than x.

Therefore, the answer is:

B. "In y = 13x, the value of y is 13 times the value of x, and in y = x + 13, the value of y is 13 more than the value of x."

The equation y = 12x means that y is equal to 12 times x. In the given situation, Yvonne has y dollars and Marie has x dollars. Yvonne has 12 times more dollars than Marie, and one half more than Marie. Therefore, the situation can be represented by y = 12x.

Answer: When Mohammed meets Han Fei, she will be 74.6 kilometers away from San Francisco.

Step-by-step explanation:

First, we need to convert Mohammed's speed from miles per hour to kilometers per hour, as Han Fei's speed is given in kilometers per hour.

40 miles per hour = 64.37 kilometers per hour (approximately)

Now, let's determine how long it will take Mohammed to reach the point where he meets Han Fei:

time = distance ÷ speed

time = 240 km ÷ 64.37 km/h

time ≈ 3.73 hours

So, after 3.73 hours, Mohammed will meet Han Fei.

In that time, Han Fei will have traveled:

distance = speed × time

distance = 20 km/h × 3.73 h

distance ≈ 74.6 km

Answer:

141 cm^2

Step-by-step explanation:

Given: V = 104 cm3, h = 8 cm

Since V = Bh, where B is the area of the base, and h is the height of a prism, then

B = V/h substitute the given values:

B = 104 cm3/8 cm

B = 13 cm2, which tells us that the long side of the square base equals the square root of 13.

The surface area of a prism = L.A. + 2B, where L.A. is the lateral area of the prism.

L.A. = pH, where p is the perimeter of the base.

Since p = 4(square root of 13) cm, h = 8cm, and B = 13 cm2, we have:

Surface Area = pH + 2B = [4(square root of 13) cm](8 cm) + 2(13 cm2) = 115.38 cm2 + 26 cm2 = 141 cm2

Thus, the surface area of the prism is approximately 141 cm2.
