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

Option C

Step-by-step explanation:

[tex]\frac{7x-3}{9} \geq 8-2x\\\\7x-3\geq 9(8-2x)\\\\7x-3\geq 72-18x\\\\7x+18x\geq 72+3\\\\25x\geq 75\\\\x\geq 3[/tex]

Option A and Option C are almost same but if we look close Option A has an open circle dot on x = 3 where as Option C has a closed circle which means that small circle at x = 3 is colored that represents [tex]x\geq 3[/tex]

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:

y = 1/2x - 7.5

Answer:

x 2 +(29/10)x-(21/10) = 0 Add 21/10 to both side of the equation : x 2 +(29/10)x = 21/10 Now the clever bit: Take the coefficient of x , which is 29/10 , divide by two, giving 29/20 , and finally square it giving 841/400 Add 841/400 to both sides of the equation

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.

Answer:

W = 3

Step-by-step explanation:

2(W - 1) + 8 = 6(2w - 4)

2w - 2 + 8 = 12w - 24

2w + 6 = 12w - 24

6 = 10w - 24

30 = 10w

3 = W

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.

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
