Which linear inequality is represented by the graph?
O y s 2x + 4
Oys2x+3
O y z 2 / 3x + 3
O y 22x + 3

Answers

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through two point (0,3) and (2,4). So, the equation of boundary line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-3=\dfrac{4-3}{2-0}(x-0)[/tex]

[tex]y-3=\dfrac{1}{2}(x)[/tex]

[tex]y=\dfrac{1}{2}x+3[/tex]

The shaded area lies below the boundary line and the boundary line is a solid line. So, the sign of inequality must be ≤.

The required inequality is

[tex]y\leq \dfrac{1}{2}x+3[/tex]

Therefore, the correct option is B.

A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign-in square inches?

Answers

Answer: The answer is 530.66

Step-by-step explanation:

I took the test and 81.64 is wrong, It's 530.66

The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².

What is the area of a circle?

The area of the circle is pi times the square of the radius of a given circle.

The area of the circle = [tex]\pi r^2[/tex]

A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.

The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.

Now, the area of the circle = [tex]\pi r^2[/tex]

the area of the circle = 3.14 × 13 × 13

= 530.66 in²

Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Answers

Answer:

–59

Step-by-step explanation:

f(x) = -2x - 7

f(x) = -2(-4x + 6) - 7

f(x) = 8x - 12- 7

f(x) = 8x - 19

f(x) = 8(-5) - 19

f(x) = -40 - 19

f(x) = - 59

The table shows the average bill totals for given numbers of diners at Simone's restaurant. If the rate is constant and you graph this relationship with the number of people along the x-axis and bill amounts along the y-axis, which points will lie on the line you get?

a. (12, 470)
b. (20, 800)
c. (24, 1,020)
d. (27, 1,080)
e. (28, 1,110)

Answers

Answer: B and D

Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080

The point (20 , 800) and ( 27 , 1080 )lies on the line.

Option (b) and (d) is correct.

It is given that average bill totals for given numbers of diners at Simone's restaurant.

To find which points will lie on the line you get.

What is co-ordinate?

Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).

The rate is constant.

Graph this relationship with the number of people along the x-axis and bill amounts along the y axis.

y = mx + c

=> 40 =m+ c

80 = 2m + c

=> m = 40

40 = 40 + c

=> c = 0

Hence

y = 40x

x = 12 => y = 480

x = 20 => y = 800

x =24 => y = 960

x = 27 => y = 1080

x = 28 => y = 1120

Hence (20 , 800) and ( 27 , 1080 ) point lies on the line
