7th grade help me plzzzzz

Step-by-step explanation:

#1. y - 5 = 5/3(x-3)

y - 5 = 5x/3 - 5

3y = 5x

#2. 3y = 3x (÷3)

y = x

#3. y - 1 = 1/3(x-3)

y - 1 = x/3 -1

3y = x

#4. y + 2 = -2/3(x-3)

y + 2 = -2x/3 + 2

3y = -2x

#5. 3y = -4x

#6. 3y = -6x (÷3)

y = -2x

(Answer is bolded, and underlined)

If we imagine that point D is on the negative side of the X axis, because right now, it is on the positive, and we need its reflection. If we flip it over, it becomes a -5, and the Y axis will stay the same, so the answer is

(-5, -3)

Answer:

(5, 3)

Step-by-step explanation:

If you kind of 'flip' the figure of=ver the x-axis, you'll see that every coordinate has the same numbers but has different positive and negative signs. If you flip the figure over the x-axis, point D will be in the first quadrant. Since the first quadrant is (positive, positive), then you change the signs to (positive, positive.)

1. quotient

2.remainder

3. a factor

4. 5

Step-by-step explanation:

i just took the test

The expression (x + 5) is a factor of given function f(x).

So the remainder of the function will be zero.

The given function is,

                      [tex]f(x) = x^3 + 3x^2 - 25x - 75[/tex]

We have to check (x + 5) is a factor of the given function.

Equate (x + 5) is equal to 0.

           x + 5 = 0

                 x = -5

Substitute x = -5 in given equation.

          [tex]f(-5)=(-5)^3+3(-5)^2-25(-5)-75\\\\f(-5)=-125+75+125-75\\\\f(-5)=0[/tex]

Since f(-5) = 0. Therefore, (x + 5) is a factor of given function f(x).

Answer:

$13,616

Step-by-step explanation:

For each year we will have to constantly decrease it by 7.5%

23,500 - 7.5%

= 21,737.5

= 21,737.5 - 7.5%

= 20,107.1875

= 20,107.1875 - 7.5%

= 18599.1484375

= 18599.1484375 - 7.5%

= 17204.2123047

= 17204.2123047 - 7.5%

= 15913.8963818

= 15913.8963818 - 7.5%

= 14720.3541532

= 14720.3541532 - 7.5%

= 13616.3275917

Definitively we will get the answer $13,616

Answer:

38 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 9.8 m/s²

Range (R) =?

Next, we shall convert 9.8 m/s² to ft/s². This can be obtained as follow:

0.3048 m/s² = 1 ft/s²

Therefore,

9.8 m/s² = 9.8 m/s² × 1 ft/s²/ 0.3048 m/s²

9.8 m/s² = 32.15 ft/s²

Thus, 9.8 m/s² is equivalent to 32.15 ft/s².

Finally, we shall determine how far away the soccer ball hit the ground (i.e range) as shown below:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 32.15 ft/s²

Range (R) =?

R = u² × Sine 2θ / g

R = 35² × Sine (2×40) / 32.15

R = 1225 × Sine 80/ 32.15

R = 1225 × 0.9848 / 32.15

R = 37.5 ≈ 38 feet.

Thus, the soccer ball hit the ground 38 feet away.

Part 1. Use x = 1.

Part 2. Use x = 0

Step-by-step explanation:

If x = 1, you have

[tex]\frac{9^1}{5^1} = \frac{9}{5}\\[/tex] , which is greater than 1.

If x = 0, you have

[tex]\frac{9^0}{5^0} = \frac{1}{1} = 1[/tex], which is NOT greater than 1.

Answer and Explanation:

The closet is 4 1/2 feet long, 2 2/3 feet deep, and 6 feet tall

Since we are not given width of the closet, we assume the base of the closet has equal width and length = 4 1/2 feet(closet base is a square)

Closet is 2 2/3 feet deep and 6 feet tall, therefore closet height internal = 8 2/3 feet

a. How much carpeting will she need?

The carpeting needed for the closet = area of base of the closet(square base)= 4 1/2* 4 1/2 = 4.5*4.5= 20.25 square feet

b. The athletic director wants to store cube boxers that are 1/2 foot wide. How many boxers will the storage hold?

Area of base = 20.25

Area of base of each cube on the floor = 0.5*0.5= 0.25

So we know that the base of the closet will hold

20.25/0.25= 81 boxer cubes

Or we could straight to the point

Find volume of the closet( the closet is clearly a cuboid) and divide by the volume of one cube to find number of cubes that will fit into the closet

Volume of the closet/cuboid = l*w*h =4.5*4.5*8.67/0.25

=702.27

Therefore number of boxer cubes to fit in closet= 702

There is no diagram for illustration but I will explain each option using assumptions

Answer and explanation:

If Emily divides -15 by 5, the result would be

-15/5=-3

The arrows should point in the negative direction: yes we have a negative result hence -3 should be on the negative side of the number line

The small arrows should end in the same place as the large one: this should be known from the diagram but I assume we are talking about decimal numbers in between whole numbers on the number line. The small arrows for decimals and the large ones for the whole numbers. Here the result is -3 therefore we should have a large arrow pointing to it, and not a small arrow

The arrows should end on negative 15: our result is -3 or negative 3 therefore the arrow should end on negative 3 and not negative 15.

The arrows should start at zero: zero is like the boundary between negative and non negative numbers. Arrows should count from 0 to negative or non negative direction on the number line

There should be 5 small arrows: there should be large arrows and less than 5 counts as our result is negative 3 and not 5

Answer:

The 12 pizzas cost  63.6$

Step-by-step explanation:

So we get 84.80 divided by 16 which is equal to 5.3

So that's mean 5.3 is the price of 1 pizza

and here they are asking how much 12 pizzas would cost

which mean that we need to get 5.3 multiply by 12 which is 63.6$

So in conclusion 12 pizzas will cost 63.6$

Answer:

Step-by-step explanation:

Since we are not asked what to find, we can as well calculate the displacement of Carrie.

Displacement will be gotten using Pythagoras theorem;

Given

direction through west x = -25m

direction through north y = 60m

Required

Displacement d

According to the theorem;

d² = x²+y²

d² = (-25)²+(60)²

d² = 625 + 3600

d² = 4225

d = √4225

d = 65 m

Hence the displacement of Carrie is 65m
