Answer:

The coordinates of the point b are:

b(x₂, y₂)  = (-5, -1)

Step-by-step explanation:

Given

As m is the midpoint, so

m(x, y) = m (-7, -2.5)

The other point a is given by

a(x₁, y₁) = a(-9, -4)

To determine

We need to determine the coordinates of the point b

= ?

Using the midpoint formula

[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

substituting (x, y) = (-7, -2.5), (x₁, y₁) = (-9, -4)

[tex]\left(-7,\:-2.5\right)=\left(\frac{x_2+\left(-9\right)}{2},\:\:\frac{y_2+\left(-4\right)}{2}\right)[/tex]

Thus equvating,

Determining the x-coordinate of b

[x₂ + (-9)] / 2 = -7

x₂ + (-9) = -14

x₂ - 9 = -14

adding 9 to both sides

x₂ - 9 + 9 = -14 + 9

x₂ = -5

Determining the y-coordinate of b

[y₂ + (-4)] / 2 = -2.5

y₂ + (-4) = -2.5(2)

y₂ - 4 = -5

adding 4 to both sides

y₂ - 4 + 4 = -5 + 4

y₂ = -1

Therefore, the coordinates of the point b are:

b(x₂, y₂)  = (-5, -1)

Answer:

Nora would have 30 papers graded in 5 hours.

Step-by-step explanation:

6 papers per hour x 5 hours = 30 papers graded in 5 hours

Answer:

Nora will have 1 page left to grade after working for 5 hours.

Step-by-step explanation:

Her constant is 6 papers per hour.

After 5 hours, she would grade 5x6 papers, which is 30 papers.

So we know she is going to grade 31 papers, and she has already done 30.

So 31-30=1, that means that she has 1 more paper left to grade.

1.)A 2.)D 3.)A 4.)C 5.)B

Step-by-step explanation:

1.) there are 15 smileys and 5 suns... and you can divide them both my 3 and get 3 over 1 or, 3 to 1.

2.) there are 8 dictionaries and 25 reference books all together including the dictionaries so you would add 8+5+12 in order to get 25...

3.) There are 16 green and 6 red and you divide both by 2 and get 8 to 3

4.) there are 6 red and 24 blue you can divide both by 6 in order to get 1 to 4

5.)there are 24 blue and 46 in all but they can both be divide by 2 in oreder to get 12 to 23

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, then

y = 3x + c ← is the partial equation

To find c substitute (1, 1) into the partial equation

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = 3x - 2 ← equation of line

Answer:

y = 3x + 2

Step-by-step explanation:

Ans : y = 3x + 2

Steps:

(2y-6x=4)/2

y=3x+2

Answer:

y ≥ 2x + 1

Step-by-step explanation:

you want to find the slope, then the y-intercept, and set the equation in slope intercept form, but imma give you a tip so you know when its either y ≥ x or  

y ≤ x, so when its y ≥ x, the shaded part will be to the left of the graph, or the top of the graph if y ≥ any number, but for y ≤ x or any number, it will be on the right side of the graph or the bottom if its a horizontal line that includes anything less then the y-intercept, but for a normal function, you can plug in values to figure out if its ≥ or ≤

Answer:

y=-1/2x+4

Step-by-step explanation:

the slope is -1/2x and y intercept is 4

The equation that can be used to find the average amount they earned per car is 42n = 252 and they earned $6 per car.

Given that a school band raised $252 by holding a car wash, they washed 42 cars in all.

We need to determine the equation that can be used to find n, the average amount they earned per car.

To find the average amount earned per car (n), you can use the equation:

n = Total amount raised / Total number of cars washed

In this case, the total amount raised is $252, and the total number of cars washed is 42.

So the equation to find n would be:

42n = 252

n = 252 / 42

Now, you can calculate n:

n = 6

Therefore, the average amount they earned per car is $6.
