2. Can you state the domain and range of a relation that is not a function? If yes, what is the
domain and range of the relation on the right?

Equivalent equations are simply equations that have the same value, irrespective of their form

1. 7 + 5x = 3 - 2x and 7 + 7x = 3

Start by solving for x in both equations

[tex]\mathbf{7 + 5x = 3 - 2x}[/tex]

Collect like terms

[tex]\mathbf{2x + 5x = 3 - 7}[/tex]

[tex]\mathbf{7x = - 4}[/tex]

Divide both sides by 7

[tex]\mathbf{x = -\frac 47}[/tex]

[tex]\mathbf{7 + 7x = 3}[/tex]

Collect like terms

[tex]\mathbf{7x = 3-7}[/tex]

[tex]\mathbf{7x = - 4}[/tex]

Divide both sides by 7

[tex]\mathbf{x = -\frac 47}[/tex]

The values of x in both equations are the same;

Hence, 7 + 5x = 3 - 2x and 7 + 7x = 3 are equivalent

2. 3 (x – 4) = 15 and x-4 = 15

Rewrite the first equation as follows

[tex]\mathbf{3 (x - 4) = 15 }[/tex]

Divide both sides by 3

[tex]\mathbf{x - 4 = 5 }[/tex]

In the second equation, we have:

[tex]\mathbf{x-4 = 15}[/tex]

The values of x - 4 are not the same in both equations.

Hence, 3(x – 4) = 15 and x-4 = 15 are not equivalent

3. x2 = 6x and x = 6

Solve for x in the first equation as follows:

[tex]\mathbf{x^2 = 6x}[/tex]

Divide both sides by x

[tex]\mathbf{x = 6}[/tex]

The results of both equations are the same.

Hence, [tex]\mathbf{x^2 = 6x}[/tex] and [tex]\mathbf{x = 6}[/tex] are equivalent

4. (x+5) = 10 and 1 = 10(x – 5)

Solve for x in the first equation as follows

[tex]\mathbf{x+5 = 10}[/tex]

[tex]\mathbf{x = 5}[/tex]

Solve for x in the second equation as follows

[tex]\mathbf{1 = 10(x - 5)}[/tex]

Divide both sides by 10

[tex]\mathbf{0.1 =x - 5}[/tex]

Add 5 to both sides

[tex]\mathbf{x = 5.1}[/tex]

The values of [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not the same

Hence, [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not equivalent

Answer:

C = 0.35x + 100

Step-by-step explanation:

0.35 is the cost per mile, and x is the number of miles. Say if x is 10, meaning you went 10 miles, you would multiply that by 0.35 to get a cost of $3.50. So, use 0.35x . The $100 is added on because it doesn’t matter how many miles were driven, you still have to pay at least that much per day.

Answer:

To find the first blank number, you can use reverse operations. Something + 7 must equal 3. So, the blank number is 7 subtracted from 3.

3-7=-4

The first blank number is -4. To find the second blank number, add 10 to the first blank number (-4).

-4+10=6

The second blank number is 6.

Hope this helps! :)

Answer:

B.

Step-by-step explanation:

The graph of b is a linear graph, meaning it's value will increase at the same rate. The graph of a, however, appears to be exponential. This means that a will increase at a rapidly higher rate that b over time. You can also tell by just looking. You can see graph a has overtaken b in the same amount of time.

Answer:

9π

Step-by-step explanation:

Let a = circumfrence of circle a

     b = circumfrence of circle b

a = 3b

circumference = 2πr

diameter = 27

radius = 27/2 (radius is half of the diameter)

a = 2π(27/2)

a = 27π

Plug in the new a

27π = 3b

Divide both sides by 3

27π/3 = 3b/3

b = 9π

Answer:

x= (y-5)/2

Step-by-step explanation:

Isolate the x variable.

y= 2x +5

Subtract 5 from both sides.

y-5=2x

Divide both sides by 2.

(y-5)/2= x

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

First, it is going upwards from left to right so we know it'll be positive. Then we do the following:

[tex]\frac{rise}{run}=\frac{change.in.y}{change.in.x}=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}=\frac{0--6}{4-0} =\frac{0+6}{4-0} =\frac{6}{4} =\frac{3}{2}[/tex]

("." in the second fraction is for separate words)

So the slope is [tex]\frac{3}{2}[/tex]
