Answer: 5 over 28 ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Step-by-step explanation:

Given:

The graph of system of inequalities.

To find:

The inequalities.

Solution:

From the given graph it is clear that dotted line is a vertical line parallel to the x-axis and one unit above the x-axis. So, the equation of dotted line is

[tex]y=1[/tex]

The area below the dotted line is shaded. It means, y values must be less than 1. So, the required inequality for dotted line is

[tex]y<1[/tex]         ...(i)

Solid line passes through (-5,-5), (0,0) and (5,5). It means y is directly proportional to x with 1 as constant of proportionality. So, the equation of solid line is

[tex]y=x[/tex]

The area above the solid line is shaded. It means, y values must be greater than or equal to x. So, the required inequality for solid line is

[tex]y\geq x[/tex]      ...(ii)

So, the system of inequalities have inequalities [tex]y<1[/tex] and [tex]y\geq x[/tex].

Therefore, the correct option is D.

Answer:

200

Step-by-step explanation:

Average means the mean of the numbers

The mean is all the numbers added together and then divided by how many numbers there are.

Since there are 3 numbers, you add them together. (150+200+250)

The three numbers together equal 600

Next, you do 600/3 since there are 3 numbers you added together.

That equals 200!

Answer:

y=2/4x+2 or simplified it's y=1/2x+2

Step-by-step explanation:

the change in y is 2 and the change in x is 4 so the change in y over the change in x is 2/4 or simplified is 1/2 and the line hits the y-axis at 2 so b or the y-intercept is 2

Answer:

subtracting one from the other

Step-by-step explanation:

The equations are not well written. Let us assume the equations are:

2x + y = 7 .... 1

2x + 2y = 5 ....2

Looking at the two equations, using elimination method will be the best way to go.

Since the coefficient of the variable x are the same, we can take the difference of both equation to cancel out the variable x and get y as shown;

(2x-2x) + (y-2y) = 7-5

0 - y = 2

y = -2

Note that you can only subtract if the coefficient of the variables in both equations have the same coefficient (same sign) and add if they have different signs

Answer:

6/10

Step-by-step explanation:

The fraction 6 / 10 shows the ratio of 3 dogs to 5 dogs is the same. Then the correct option is A.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The ratio of 3 dogs to 5 dogs will be given as,

Ratio = 3 / 5 = 0.60

Let's check all the options, then we have

A)  6 / 10, then the ratio is given as,

Ratio = 6 / 10 = 0.60

B)  27 / 40, then the ratio is given as,

Ratio = 27 / 40 = 0.675

C)  9 / 10, then the ratio is given as,

Ratio = 9 / 10 = 0.90

D)  12 / 15, then the ratio is given as,

Ratio = 12 / 15 = 0.80

The fraction 6 / 10 shows the ratio of 3 dogs to 5 dogs is the same. Then the correct option is A.

A= –65/81

Step-by-step explanation:

hope this explains it

The solution of the given equation will be 16/81.

Given that:

Equation, [tex]\rm \left ( \dfrac{2}{3} \right)^{x + 4} = A \cdot \left ( \dfrac{2}{3} \right)^x[/tex]

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

Simplify the equation, then we have

[tex]\rm A \cdot \left ( \dfrac{2}{3} \right)^x=\left ( \dfrac{2}{3} \right)^{x + 4} \\\\\rm A \cdot \left ( \dfrac{2}{3} \right)^x=\left ( \dfrac{2}{3} \right)^{x }\left ( \dfrac{2}{3} \right)^4[/tex]

Further, simplify, then we have

A = (2/3)⁴

A = 16/81

Answer:

Area

Step-by-step explanation:

Surface area is 55278.36 when Earth's diameter is approximately 1.2756 x 104 kilometers.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given,

Earth's diameter is approximately 1.2756 x 104 kilometers.

Diameter=1.2756 x 104=132.66km

Radius =Diameter/2=66.33 km

We need to find surface area of earth by formula

Surface area = 4πr²

= 4×3.142×(66.33)²

=55278.36

Hence, the surface area is 55278.36 when Earth's diameter is approximately 1.2756 x 104 kilometers.
