Answer: The value of x is 20

Step-by-step explanation:

The angles are vertical angles so they have to equal each other in other to solve for x.

(x + 40) = 3x          

x + 40 = 3x     subtract x from both sides

-x            -x

40 = 2x     Divide both side by 2

x= 20

Problems a through c are asking you what the values would be at those values.

What will the value of [tex]f(x)[/tex] be at [tex]x=0[/tex]? Let's look at the graph.

It seems at [tex]x=0[/tex], [tex]f(x)=0[/tex], meaning that [tex]f(0)=0[/tex]

Let's do the same for the others.

At [tex]x=-3[/tex], [tex]f(-3)=2[/tex]

At [tex]x=2[/tex], [tex]f(2)=-4[/tex]

For the last question, it is giving us the [tex]f(x)[/tex] value and asking us which [tex]x[/tex] values would give us that.

At [tex]f(x)=3[/tex], [tex]x=-2[/tex].

*Note* this function is continuous to the right, meaning that there is another point where [tex]f(x)=3[/tex].

Hope this helps.

Step-by-step explanation:

Answer:

Emily will contribute $24 and Anna will contribute $96

Step-by-step explanation:

From the given information:

Let Emily's salary be x

and let Anna's salary be 4x since Anna's salary is four times Emily's salary.

They were to share the cost of a $120 gift card.

SO, x+4x = 120

5x = 120

x = 120/5

x = 24

Therefore, Emily will contribute x = $24

and Anna will contribute 4x = 4 × $24  = $96

Answer: your answer is going to be 1/7

Step-by-step explanation:

Answer:

x = -1/7

Step-by-step explanation:

First, combine like terms:

3 - 21x = 6

Then, isolate the variable:

-21x = 3

Then, divide -21 on both sides:

x = -3/21

Finally, simplify the fraction:

x = -1/7

Answer: 22.59 yd^3

Step-by-step explanation:

First the volume of a cuboid whose measurements are:

L = length, W = width and T = thiknes is:

V = L*W*T.

We want to calculate the volume of a shape that is:

10'' thick, 18' wide and 42' long.

This notation is:

(') = feet

('') = inches

The first step is to write our 3 numbers in the same units, then we can use that:

1 inch = 0.083 ft.

Then 10 inches are equal to:

10'' = 10*(0.083 ft) = 0.83 ft = 0.83'

Then the volume of concrete needed will be:

V = 0.83ft*18ft*42ft = 627.48 ft^3

But we want this expressed in yd^3

1ft = 0.33 yd

then

1ft^3 = (0.33 yd)^3 = 0.036 yd^3

then 627.48 ft^3 can be written as:

627.48 ft^3 = 627.48*( 0.036 yd^3) = 22.59 yd^3

Answer:

$21.50

Step-by-step explanation:

We want to find Anthony's pay for 43 hampers.

We can multiply his pay per hamper by the number of hampers picked.

pay per hamper * hampers picked

He earns $0.50 for each hamper and he picked 43 hampers. Therefore, we can multiply $0.50 and 43 to find his pay for the day.

$0.50 * 43

$21.5 = $21.50

Anthony's total pay that day is $21.50.

Find common denomianators.

1/4 = 5/20

1/10 = 2/20

Add.

5/20 + 2/20 = 7/20

Therefore, the answer is 7/20.

Best of Luck!

Answer:7/20

Step-by-step explanation:first you have to find the common denominator which is twenty. Since 4x5 is 20 you multiply the 1 by five and get 5/20.

Then since 10x2 is 20 you have to muliply

1x2 and you get 2/20. Then you and 5/20 and 2/2o and you get 7/20

Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.

The given statement is False

The following information should be considered:

[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]

based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.
