For the linear equation y = -3.5x + 50 the graph is plotted with points (0,50) and (14.28,0).

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The linear equation is y = -3.5x + 50.

An arcade deducts 3.5 points from a 50-point game card for each game played.

The graph will represent the x axis as number of games played.

The graph will represent the y axis as points earned.

Substitute the value x = 0 in the equation -

y = -3.5(0) + 50

y = 50

The coordinate point is (0,50).

Substitute the value y = 0 in the equation -

0 = -3.5x + 50

-50 = -3.5x

x = 14.28

The coordinate point is (14.28,0).

Plot both the coordinate points and join the line.

Therefore, the graph is plotted for the linear equation.

On solving the provided question, we can say that ratio is = 2:5:7 => 2x + 5x + 7x = 84 => x =  6 and A gets = 2x = 12 rs.

Ratios show how often one number is contained in another in mathematics. For instance, the ratio of oranges to lemons in a fruit dish is 8 to 6 if there are 8 oranges and 6 lemons present. In a similar vein, the proportion of oranges to whole fruit is 8, while that of lemons to oranges is 6:8. A ratio is an ordered pair of numbers a and b that is expressed as a / b, with b not equal to zero. An equation equating two ratios is known as a ratio. The ratio can be expressed as 1:3, for instance, if there is 1 boy and 3 girls (for every boy she has 3 girls) 3/4 are girls, while 1/4 are boys.

ratio is = 2:5:7

2x + 5x + 7x = 84

14x = 84

x = 84/14 = 6

a gets = 2x = 12 rs.

Answer: A baker needs to make a dessert for a party. The recipe calls for 1 3/4 cups of sugar, but the baker only has 1/2 cup measuring cups. How many measuring cups does the baker need to measure out the sugar for the recipe?

We can start by converting the mixed number 1 3/4 into an improper fraction: 1 3/4 = 7/4. Then, we can divide 7/4 by 1/2:

7/4 ÷ 1/2 = 7/4 * 2/1 = 14/4 = 3 1/4

The baker needs 3 1/4 measuring cups to measure out the sugar for the recipe.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

the midsegment EF of the trapezoid ABCD is half the sum of the parallel bases, that is

EF = [tex]\frac{AB+DC}{2}[/tex] ( substitute values )

x + 6 = [tex]\frac{2x-9+x+5}{2}[/tex]

x + 6 = [tex]\frac{3x-4}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

2x + 12 = 3x - 4 ( subtract 3x from both sides )

- x + 12 = - 4 ( subtract 12 from both sides )

- x = - 16 ( multiply both sides by - 1 )

x = 16

Then

EF = x + 6 = 16 + 6 = 22

By using the graph, the average rate of change of the function f from 2 to 5 is equal to -1.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f from the graph over the interval [2, 5]:

a = 2; f(a) = 4

b = 5; f(b) = 1

Substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (1 - 4)/(5 - 2)

Answer:

2w^2.

Step-by-step explanation:

Let "w" be the width of the walkway. Then, the length of the garden is 6.5(6x + 6) - 2w and the width of the garden is 6.5(6x + 6) - 2w.

The area of the garden is 6(4.5x + 2.5) = 6 * 4.5 * x + 6 * 2.5 = 27x + 15

The area of the garden and walkway is (6.5(6x + 6) - 2w)^2 = 27x + 15 + 2w^2

Equating the two expressions for the area of the garden:

27x + 15 = 27x + 15 + 2w^2

Thus, the area of the walkway is:

The number of fifty dollars with the manager are 31.

Two or more expressions with an Equal sign is called as Equation.

Given that a convention manager finds that she has $1370, made up of twenties and fifties.

20x+50y=1370

She has a total of 46 bills.

x+y=46

x=46-y

Now we have to plug in x value in equation 1

20(46-y)+50y=1370

920-20y+50y=1370

920+30y=1370

Subtract 920 on both sides

30y=450

Divide both sides by 30

y=15

Now plug in y value in x+y=46

x+15=46

Subtract 15 on both sides

The size of the crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route is 44000 people.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, the size of a crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route,

The number of people that can fit comfortably in a 6 feet by 6 feet area = 10

The ratio of the number of people per unit area = 10/(6 × 6) = 10/36

The area, A, occupied by the crowd = 5 feet × 3 mile × 2

3 miles = 15840 feet

∴ A = 5 feet × 15840 feet × 2 = 158400 ft²

We then have;

Number of people / 158400 = 10/36

Number of people = 44000

Hence, the size of the crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route is 44000 people.

a. To find the relative frequency of people that chose romance, we need to count the number of times the letter "R" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "R" appears in the sequence is: R, R, R, R, R, R, H, R = 7

The total number of letters in the sequence is: 26

Relative frequency of people choosing romance = 7/26 = 0.269 or approximately 0.27.

b. To find the relative frequency of people that chose comedies, we need to count the number of times the letter "C" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "C" appears in the sequence is: C, C, C, H, C, C, H, H, C, C = 9

The total number of letters in the sequence is: 26

Relative frequency of people choosing comedies = 9/26 = 0.346 or approximately 0.35.

c. To find the relative frequency of people that chose horror, we need to count the number of times the letter "H" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "H" appears in the sequence is:

H, H, H, H, H, H, H = 7

The total number of letters in the sequence is: 26

Relative frequency of people choosing horror = 7/26 = 0.269 or approximately 0.27.

g. Based on the relative frequencies calculated, it can be seen that comedies is the most popular movie genre among the class, as it has the highest relative frequency of 0.35.

h. Based on the relative frequencies, it can be seen that romance is the least popular movie genre among the class, as it has the lowest relative frequency of 0.27. Hence, if we were having a party for the class, we would be least likely to pick romance as the genre of movie to watch.
