Answer:

When <u>graphing inequalities</u>:

< or > : draw a dashed line

≤ or ≥ : draw a solid line

< or ≤ : shade under the line

> or ≥ : shade above the line

<u>Question 14</u>

Given inequalities:

y \geq x - 3

y > -4x + 2

Treat the inequalities as equations (swap the inequality sign for an equals sign) to find two points on the line to help draw the lines.

y \geq x - 3

x=0 \implies y=-3

x=3 \implies y=0

Plot the points (0, -3) and (3, 0).

Draw a <u>solid straight line</u> through the points.

y > -4x + 2

x=0 \implies y=2

x=1 \implies y=-2

Plot the points (0, 2) and (1, -2)

Draw a <u>dashed straight line</u> through the points.

Shade the intersecting area <u>above</u> the two lines.

<u>Question 15</u>

Given inequalities:

y \geq -3x - 3

y \geq -\dfrac{1}{2}x + 2

Treat the inequalities as equations (swap the inequality sign for an equals sign) to find two points on the line to help draw the lines.

y \geq -3x - 3

x=0 \implies y=-3

x=-2 \implies y=3

Plot the points (0, -3) and (-2, 3).

Draw a <u>solid straight line</u> through the points.

y \geq -\dfrac{1}{2}x + 2

x=0 \implies y=2

x=2 \implies y=1

 Plot the points (0, 2) and (2, 1)

Draw a <u>solid straight line</u> through the points.

Shade the intersecting area <u>above</u> the two lines.

A regular pentagonal prism has a volume of 2,850 cubic millimeters. what is the height of the prism? a regular pentagonal prism
zlopas [31]

Answer:

Height = 19mm.

Step-by-step explanation:

Area of a regular polygon =  (A * P) / 2 where A = side / (2 * Tan (π / N)) where, N = Number of sides, A = Apothem,  P = Perimeter.

Here A = 5, P = 5*12 = 60 so

Area  of the base  = (5 * 60) / 2 = 150 mm^2.

Volume = area base * height so

Height = volume / area of base

            = 2850 / 150

            = 19 mm.

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8

The equation y = 36 + 18x models the relationship
wariber [46]

Answer:

Option B) The height, in inches, of a typical apple tree

Step-by-step explanation:

Let

x----> the number of years, after the tree was planted

y ---> the height in inches, of a typical golden  delicious apple tree

we have

y=36+18x

Remember that

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The y-intercept is the height of the tree when it was planted (x=0)
