Which of the following points lies in the solution set of the inequality y > 3x +10?
shepuryov [24]

Since 3 is greater than -3, hence (-1, 3) lie in the solution set. Option C is correct

In order to determine the points that lie in the solution set of the inequality y > 3x +10, we will substitute the x-coordinate and see if <u>y is greater than the result.</u>

<u />

For the coordinate point (1, 10)

y > 3(1) +10

y > 13

Since 10 is not greater than 13, hence (1,10) does not lie in the solution set.

For the coordinate point (4, 20)

y > 3(4) +10

y > 22

Since 20 is not greater than 22, hence (4,20) does not lie in the solution set.

For the coordinate point (-1, 3)

y > 3(-1) +10

y > -7

Since 3 is greater than -3, hence (-1, 3) lie in the solution set.

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you
bija089 [108]

Answer:

A=6.33\ cm^2

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

C=2\pi r

we have

C=\frac{28}{3.14}\ cm

\pi=3.14

substitute the values

\frac{28}{3.14}=2(3.14)r

r=\frac{28}{19.7192}\ cm

r=1.42\ cm

step 2

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

substitute the values

A=(3.14)(1.42)^{2}

A=6.33\ cm^2
