we have

y> -3x+2

The solution is the shaded area above the dotted line

we know that

If a point is a solution of the inequality, then the coordinates of the point must satisfy the inequality

We will verify all cases to determine the solution of the problem

<u>Case A)</u> Point (0,2)

x=0\\y=2

Substitute the value of x and y in the inequality and verify

2> -3*0+2

2>2 -------> is not true

therefore

the point (0,2) is not a solution of the inequality

<u>Case B)</u> Point (2,0)

x=2\\y=0

Substitute the value of x and y in the inequality and verify

0> -3*2+2

0>-4 -------> is true

therefore

the point (2,0) is a solution of the inequality

<u>Case C)</u> Point (1,-2)

x=1\\y=-2

Substitute the value of x and y in the inequality and verify

-2> -3*1+2

-2>-1 -------> is not true

therefore

the point  (1,-2) is not a solution of the inequality

<u>Case D)</u> Point (-2,1)

x=-2\\y=1

Substitute the value of x and y in the inequality and verify

1> -3*(-2)+2

1>8 -------> is not true

therefore

the point (-2,1) is not a solution of the inequality

therefore

<u>the answer is the Point B</u>

(2,0)

To better understand the problem see the attached figure

An infinite geometric series has a first term ai = 15 and a sum of 45. Explain how you
oee [108]

Answer:

r= \frac{2}{3}

Step-by-step explanation:

The sum to infinity of a geometric series is calculated as

S∞ = \frac{a_{1} }{1-r} ; | r | < 1

where a₁ is the first term and r the common ratio

here a₁ = 15 and S∞ = 45 , then

45 = \frac{15}{1-r} ( multiply both sides by (1 - r ) )

45(1 - r) = 15 ( divide both sides by 45 )

1 - r = \frac{15}{45} = \frac{1}{3} ( subtract 1 from both sides )

- r = \frac{1}{3} - 1 = - \frac{2}{3} ( multiply both sides by - 1 )

r = \frac{2}{3}
