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.

Ad libitum [116K]

Answer:

y = -0.07x2 + 3.07x

Step-by-step explanation:

For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.

So, for 2 plants, we have (3 - 0.07) * 2

For 3 plants, we have (3 - 2*0.07) * 3

For x plants, we have (3 - (x-1)*0.07) * x

So we can model the final result of the amount of beans 'y' with the equation:

y = (3 - (x-1)*0.07) * x

y = (3 - 0.07x + 0.07) * x

y = (3.07 - 0.07x) * x

y = -0.07x2 + 3.07x

(In this equation we have a = -0.07, b = 3.07 and c = 0)

A mountain bike originally priced at $960.00 is up for sale at a discount of 14%. What is the price of the mountain bike after t
PilotLPTM [1.2K]

Answer:

$825.60

Step-by-step explanation:

Since the price of it is $960.00, it means that it's 100%.

100% = 960

1% = 960 ÷ 100 = 9.6

14% = 9.6 x 14 = 134.40

Since they asked for after the discount, deduct the price of the discount with the original price.

Mountain bike after 14% discount =

960 - 134.40 = 825.60
