All the other points listed are in the side of points that do not belong to the set of soluctions.

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)

How do you Change 0.3 to a fraction?
ArbitrLikvidat [17]

Answer:

3/10

Step-by-step explanation:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Jeff was already 7 miles out of town when his sister
Nikolay [14]

The sister catches up Jeff after 2 hours

Step-by-step explanation:

We can write Jeff's position and his sister position at time t using the following expressions:

- Jeff position:

x_j(t) = 7 + 2.5 t

where:

7 is the initial position of Jeff when his sister sarts chasing him

2.5 is Jeff's velocity (in miles/hour), so its position increases by 2.5 miles for each hour

t is the time measured in hours

- Sister position:

x_s(t) = 6t

where

6 is the sister velocity (her position increases by 6 miles for every hour)

t is the time measured in hours

The sister catches up Jeff when the two positions are equal, so

x_j(t) = x_s(t)\\7+2.5t=6t

And solving for t,

7+2.5t-2.5t=6t-2.5t\\7=3.5t\\t=\frac{7}{3.5}=2 h

So, the sister catches Jeff after 2 hours.

What is the circumference of the circle? Show steps please!
Marina CMI [18]

Area = r^2 x PI

to find r take the square root of the area:

r = √100 = 10

The circumference of a circle is the diameter times PI.

The diameter is 2 times r = 2 x 10 = 20

The circumference = 20PI m

The answer is C.
