  • original correct coordinates of D : (7, 3)

  • x is the horizontal axis.
  • y is the vertical axis.

Here Allie mistook the x and y axis completely oppositely.

→ First should be the x axis and then the y axis, (x, y)

Answer:

Step-by-step explanation:

Coordinates of a point are usually represented by (x, y) where x describes the horizontal distance from the y-axis and y describes the vertical distance from the x-axis.

<u>Point A</u>

4 units from the y-axis ⇒ x = 4

6 units from the x-axis ⇒ y = 6

A = (4, 6)

<u>Point B</u>

2 units from the y-axis ⇒ x = 2

9 units from the x-axis ⇒ y = 9

B = (2, 9)

<u>Point C</u>

0 units from the y-axis ⇒ x = 0

4 units from the x-axis ⇒ y = 4

C = (0, 4)

<u>Point D</u>

Allie has mixed up the x and y coordinates of D.

7 units from the y-axis ⇒ x = 7

3 units from the x-axis ⇒ y = 3

D = (7, 3)

Emily wants to plant flowers in an area with angular but that is 1 foot by 4.5 ft. the flowers she wants to plant need to be spa
lukranit [14]

Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.

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

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w)

In this question, the perimeter is of 1 ft by 4.5, thus, l = 1, w = 4.5, and the perimeter is:

P = 2(1 + 4.5) = 2(5.5) = 11

  • Perimeter of 11 ft.
  • The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:

1 plant - 2/3 ft

x plants - 11 ft

Applying cross multiplication:

\frac{2x}{3} = 11

2x = 33

x = \frac{33}{2}

x = 16.5

At least 8 inches apart(can be more), thus she should buy at most 16 plants.

If the freshman class of 63 students has 11 more boys than girls, determine how many of each are in the class.g 1
torisob [31]
B + G = 63
B = G + 11

G + 11 + G = 63
2G + 11 = 63
2G = 63 - 11
2G = 52
G = 52/2
G = 26 <=== 26 girls

B = G + 11
B = 26 + 11
B = 37 <=== 37 boys

1. K is the midpoint of HN. HK = 4x + 5 and<br> HN = 11x – 11. Solve for x and find KN.
galben [10]

Answer:

see explanation

Step-by-step explanation:

Since K is at the midpoint of HN then HK = KN = 4x + 5, thus

HN = HK + KN ← substitute values

11x - 11 = 4x + 5 + 4x + 5, that is

11x - 11 = 8x + 10 ( subtract 8x from both sides )

3x - 11 = 10 ( add 11 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Hence

KN = 4x + 5 = (4 × 7) + 5 = 28 + 5 = 33
