The correct answer is option D, "The total Number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce."

Given that a straight line with a positive slope begins at point (0,50) and ends at point (5.5,600), we are required to identify which of the given scenarios is most likely shown on the graph. We will discuss each scenario and determine which one matches the given line on the coordinate plane.

Let us discuss each scenario one by one:

Scenario 1: The total amount of money in the cash register, y, containing $50 in change and small bills and x $100 bills.In this scenario, there are two variables - x and y, where x is the number of $100 bills in the cash register, and y is the total amount of money in the cash register. The initial value of y is $50 since it is already in the cash register.

However, we don't know the value of x. Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph.

Scenario 2: The total number of puzzle pieces, y, in a brand new 50-piece puzzle, and x brand-new 100-piece puzzles.In this scenario, there are two variables - x and y, where x is the number of 100-piece puzzles, and y is the total number of puzzle pieces. Again, we don't know the value of x.

Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph

.Scenario 3: The total weight of the barbell, y, where the bar weighs 50 pounds and x 100-pound weights are added to it.In this scenario, there are two variables - x and y, where x is the number of 100-pound weights added to the bar, and y is the total weight of the barbell. The initial value of y is 50 pounds, which is the weight of the barbell. However, we don't know the value of x. Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph.

Scenario 4: The total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce. In this scenario, there are two variables - x and y, where x is the number of ounces of salad dressing, and y is the total number of calories in the salad. The initial value of y is 50 calories, which is the calorie content of the vegetables.

The calorie content of salad dressing is given as 100 calories per ounce. Therefore, the equation that relates x and y is:y = 100x + 50This is a linear equation in two variables, and the graph of this equation will be a straight line. Let us verify if this equation matches the given line on the coordinate plane.

Using the two given points on the line, we can find the slope of the line. The slope of the line is given by:m = (y2 - y1) / (x2 - x1)m = (600 - 50) / (5.5 - 0)m = 550 / 5.5m = 100

Therefore, the equation of the line is:y - 50 = 100(x - 0)y = 100x + 50This is the same equation as we obtained earlier. Hence, we can conclude that this scenario is the one shown on the graph.

Therefore, the correct answer is option D, "The total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce."

Answer:

f(x) = sin(x)

Step-by-step explanation:

The graph above is the exact parent graph of f(x) = sin(x).

f(x) = cos(x) would have an y-intercept of 1, and would not be correct.

The negative functions would be incorrect as it would be flipped.

Answer:

13.1%

Step-by-step explanation:

The company estimated that there would be 500 a ps during the football season

The actually sold 575

Therefore the percent error can be calculated as follows

= 575-500/575 × 100

= 75/575 × 100

= 0.1304×100

= 13.1%

Hence the percent error is 13.1%

Answer: No, (2,4) is not a solution to the equation y = x-2

===============================================

Explanation:

We can show this by plugging x = 2 into the equation. We should get y = 4 if (2,4) was a solution

y = x-2

y = 2-2 ... replace x with 2

y = 0

Since we didn't get y = 4, this means (2,4) is not a solution

-----------------

A similar method would be to do these steps

y = x-2

4 = 2-2 ... replace x with 2, replace y with 4

4 = 0 ... false equation

The false equation shows y = x-2 is not true when (x,y) = (2,4)

-----------------

The graph of y = x-2 does not have the point (x,y) = (2,4) on the line.

So this is a visual way to confirm (2,4) is not a solution to y = x-2.

See the graph below.

(2, 4) is not a solution to the equation y = x - 2.

Given,

(2, 4)

We need to see whether (2, 4) is a solution to the equation y = x - 2.

The solutions are the values that satisfy the equation.

Example: y = x + 1

(1, 2) is a solution to y = x + 1.

( 1, 2 ) = ( x, y )

2 = 1 + 1

2 = 2

We have,

(2, 4) = (x, y)

y = x - 2

Put x = 2 and y = 4

4 = 2 - 2

4 = 0

Which is not true.

Thus (2, 4) is not a solution to the equation y = x - 2.

The answer is 5 ft squared

Step-by-step explanation:

so you have the find the area of the circle first and you do that by starting with the formula which is

pi r2

the diameter is 2.45 so you divide that by to to get the radius and get 1.25

the you would multiply 1.25 times 1.25 times 3.14, and get 4.91 which rounds to by the nearest whole umber as 5 ft 2.

Answer:

7x = 42

Step-by-step explanation:

This equation can be solved by isolating the variable.

Explanation:

To solve an equation like this, the first step is to isolate the variable. This means that we need to get x on one side of the equal sign by itself. This is the only way we can solve for x.

In this case, we isolate x by dividing both sides by seven.

Answer:

ears to paws to tails,

which is 6 to 12 to 3.

4 paws to every tail.

2 paws to every ear.

Step-by-step explanation:

The ratio of ears, paws, and tail will be 6:12:3.There are 4 paws to every tail and 2 paws to every ear.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that,

Number of cats in room = 3

Each cat has 2 ears, 4 paws, and 1 tail.

If there are three cats total number of ears, paws, and tails will be three times the individual as 6,12, and 3.

As a result,

The ratio of ears, paws, and tail will be 6:12:3.

There are 4 paws to every tail.

There are 2 paws to every ear.

Thus, the ratio of ears, paws, and tail will be 6:12:3.There are 4 paws to every tail and 2 paws to every ear.

Answer:

n=1

Step-by-step explanation:

Use the distributive property to multiply 4 by 4−8n.

16−32n−7n=−30+7n

Combine −32n and −7n to get −39n.

16−39n=−30+7n

Subtract 7n from both sides.

16−39n−7n=−30

Combine −39n and −7n to get −46n.

16−46n=−30

Subtract 16 from both sides.

−46n=−30−16

Subtract 16 from −30 to get −46.

−46n=−46

Divide both sides by −46.

n=−46/−46

Divide −46 by −46 to get 1.

n=1

Answer: n = 1

Step-by-step explanation:

Using the distributive law, multiply 4 by what's in the bracket.

(4)(4) -(8n)(4) -7n = -30 + 7n

16 -32n -7n = -30 + 7n

Group all like terms together. Once a (+ve) number goes over the equal sign it now becomes a (-ve) number, vise versa.

16 +30 = 32n + 7n + 7n

46 = 46n

Now we need to find for n. 46n can also be written as 46 multiply by n. When a multiplication sign goes over the equal sign, the sign changes to a division sign.

46 = 46n

46/46 = n

1 = n
