Answer:

y = 3/4x -1/4

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅ Y = 3/4x - 1/4

Y=3/4x - 1/4 that is the answer.

Answers

Answer:

The ratio 15:73 represents the ratio of 7th-grade football players to total players.

Step-by-step explanation:

If you add all the players together, you get 73. The number of 7th-grade football players is 15.

This is really simple! If you add the students all together you get 73! While 15 is the amount of 7 graders playing football. So 15:73

There are 63 students in Grade 6. If the ratio of students who have black shoes to white shoes is 3:4, how many students have black shoes?

what is the equation of the line slope intercenpt form that passes through the point (8,9) and is parallel to the graph of y=3/4x-2? please explain.

Answers

Answer:

Slope-intercept form is y= 4x - 30

Step-by-step explanation:

Step 1: Substitute the slope from original line into the equation of the line

Here slope , m is 4

y= mx +b

where m is the slope

b is the y intercept

So Substituting slope we get,

y= 4x +b--------------------------------------------(1)

Step 2 :Substitute the given point (8,2) into the x and y values of equation (1)

y = 4x +b

2 =4(8) + b

Step 3: Solve for y intercept values

2 = 32+ b

2-32 =b

-30 =b

Now the y intercept value b= -30

Step 3: Substitute this value for 'b' in the slope intercept form equation

Substituting the value in eq (1) we get,

y= 4x +(-30)

y= 4x - 30

hope this helps!

Mrs. Lowry is ordering car decals for each family to put on their cars for the upcoming baseball season. She ordered 25 decals. She got a deal on them and they will be $2 cheaper for each decal. The total came to $250. Write an equation to find the amount, d, for the normal cost of each car decal without the deal.

What is the normal cost of each decal without the deal?

Answers

Answer:

$12

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

Let the cost of each car decal is d.

After applying a discount of $2 the total for 25 decals came to $250.

Set up an equation:

25(d - 2) = 250

Solve it for d:

25(d - 2) = 250d - 2 = 250/25d - 2 = 10d = 10 + 2d = 12

The normal cost of each decal is $12.

Thus, the equation of the line is given by:

Therefore, the equation of the line in standard form is

PART B:

To write the equation with a function notation, we first express y in terms of x and then change y notation to f(x) notation.

Recall from part 1:

Therefore, the equation obtained in Part A written using function notation is given by:

PART C:

To graph the equation obtained above, we draw the x- and y- axis with the x-axis labelled 'number of hours' and the y-axis labelled 'total rent'.

Next, we choose appropriate scales for x- and y- axis. Depending on the size of your graph book, you can choose an interval of 1 unit for the x-axis and an interval of 10 units for the y-axis.

From part A, we know that the line of the equation passes though points (3, 43) and (8, 113), mark these points and draw a straight line passing theough these points.

At the Wild West amusement park, Florence's favorite ride is the Blazing Bullet roller coaster. The roller coaster normally has a lot of seats to choose from, but Florence noticed that 12 of the seats are now reserved for season pass holders. There are 42 seats remaining for people without season passes. Let s represent the total number of seats on the Blazing Bullet roller coaster. Which equation models the problem?

Answers

Answer:

s=42+12

if there were 42 seats remaining and 12 seats reserved, adding both of them together would give you the total number of seats

The width of a new barn is 27 meters across. Nine meters is equal to approximately ten yards. How many yards wide is the new barn?

Answers

Answer:

If 9 meters is equal to 10 years, then you just need to find out how many times 9 goes into 27 and then multiply that by 10!

9 * 3 = 27

3 * 10 = 30!

Step-by-step explanation:

Hope it helps! =D

The answer is 30 because its 27 meters wide but the questions wants to answer in yards. So it tells you 9 meters is about 10 yards so we divide the 27 by 9 so we can change the unit measure. 27/9=3 3x10= 30

Dani's estimate for the cost of tiling her bathroom floor is $50 plus $3 per square foot. Write a linear equation showing the total cost.

Answers

Answer:

The linear equation showing the total cost of tiling Dani's bathroom floor is: y = 3x + 50

The equation is in the form of "y = mx + b", where y represents the total cost, x represents the number of square feet, m represents the cost per square foot ($3), and b represents the fixed cost ($50). The linear equation is determined by using the information provided in the problem, which is the cost per square foot and the fixed cost.
