Answer: C) y ≥ 3x - 2; $y\leq \dfrac{1}{2}x+3$

<u>Step-by-step explanation:</u>

Blue line:

y-intercept (b) = -2

slope (m) is 3 up, 1 right = 3

shading is above

⇒ y ≥ 3x - 2

Yellow line:

y-intercept (b) = 3

slope (m) is 1 up, 2 right = $\dfrac{1}{2}$

shading is below

$\implies \bold{y\leq \dfrac{1}{2}x+3}$

padma mixes 300ml of her favourite drink.she uses 15% orange juice and 5% pineapple juice.the rest is lemonade. how many ml of l

mestny [16]

Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%

Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml

So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240

In short, Your Answer would be: 240 ml

Hope this helps!

Write the equation of a circle with endpoints of the diameter are (-8, 1) and (4,5)

STatiana [176]

centre of the circle =Midpoint of the diameter

centre of the circle=

$( \frac{ - 8 + 4}{2} , \frac{5 + 1}{2} ) = ( - 2 ,3)$

radius of the circle=

$\sqrt{(4 - ( - 2) ^{2} + (5 - 3 )^{2} } = \sqrt{36 + 4} = \sqrt{40 } = 2 \sqrt{10}$

equation of the circle: (x+2)²+(y-3)² = 40

ie.. x²+4x+4+ y²- 6y+ 9=40

ie... x²+y²+4x-6y-27=0

this is the answer......

The total cost of a color printer is $186.16 including tax. If the tax rate is 7%, what is the original cost of the color printe

Galina-37 [17]

Answer:

<u>The original cost of the printer before adding the tax was $ 173.98</u>

Step-by-step explanation:

Total cost of the color printer, including tax = $ 186.16

Tax rate = 7%

Original cost of the printer, before tax = x

For answering the question, let's use the Rule of Three Simple, this way:

Percentage Value

107% 186.16

100% x

x * 107 = 186.16 * 100

107x = 18,616

x = 18,616/107

x = 173.98

<u>The original cost of the printer before adding the tax was $ 173.98</u>

Answer:

See below

Step-by-step explanation:

The first two questions are slope = 0

a horizontal line has zero slope

slope = rise/run = 0 / run = 0

Greatest y value is + 4 from x = 3 to 4

the least y value is -3 fro x = -4 to -3
