A trapezoid has one base measuring 12', and the other measuring 13'8". What is the area in square feet if the height of the trapezoid is 9'4"?

(Remember for trapezoids A= (b1 + b2)/2 x h

Answer:

slope=2/2 or 1

Step-by-step explanation:

From (-2,0) rise up by 2 and then run to the right and land on 2. So the slope will be 2/2. To simplify it's 1.

Remember this Rise goes⬆/Run to the right➡ or the other way around depends on how the graph is but you get my drift, right? ☺

Answer:

It is y = -4x + 9

Step-by-step explanation:

General equation of a line:

[tex]y = mx + c[/tex]

For a y-intercept, c :

consider point (2, 1):

y is 1, x is 2 and m is -4

[tex]y = mx + c \\ 1 = (2 \times - 4) + c \\ 1 = - 8 + c \\ c = 1 + 8 \\ c = 9[/tex]

therefore, equation is:

[tex]y = - 4x + 9[/tex]

The complete form of the equation is y = - 4x + 9

The slope intercept form of the line is given as:

y = - 4x + c

Where c = intercept , we need to calculate, c

Take any given value of y and x and substitute into the equation, the solve for c

Take x = 1, y = 5

5 = - 4(1) + c

5 = - 4 + c

Add 4 to both sides

5 + 4 = - 4 + c + 4

9 = c

Hence, the complete form of the equation is y = - 4x + 9

The range of a function is the set of possible values that can be obtained from the dependent variable. The range of the function is: [tex]R: (500, \infty)[/tex]

Given that:

[tex]Phone = \$500[/tex]

[tex]Monthly\ Plan = \$60[/tex]

Let the number of months be t. So, the function C(t) is calculated as follows:

[tex]C(t) = Phone + Monthly\ Plan \times t[/tex]

[tex]C(t) = 500 + 60 \times t[/tex]

[tex]C(t) = 500 + 60t[/tex]

The range is calculated as follows:

The smallest possible value of t is 0 i.e. when no monthly subscription is done.

So, we have:

[tex]C(0) = 500 + 60\times 0= 500 + 0 = 500[/tex]

And the highest is [tex]\infty[/tex] i.e. for a large value of t

So, we have:

[tex]C(\infty) = 500 + 60\times \infty= 500 + \infty = \infty[/tex]

Hence, the range of the function is:

[tex]R: (500, \infty)[/tex]

Answer:

8

Step-by-step explanation:

the relationship of one "unit" (bolt) of cloth to 47 people makes this number (47 people) also an unit.

to answer the question we need to find out, how many units fit into the target.

how do we do that ? by division.

when we divide a/b, then we are actually asking, how many times does b fit into a.

so, how many bolts are needed for 376 people ?

well, how often does 47 fit into 376 ? how often can we build groups of 47 people out of the 376 ?

the answer

376 / 47 = 8

so, 8 bolts are needed.

Answer:

1 bolts = 47 people

so, 47+47+47+47+47+47+47+47= 376 people

The answer is 8 bolts

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Answer:

The correct option is choice D.  x^2+y−2

Algebraic expression means that equation needs to have one variable, meaning any alphabet and one kind of operation. Operations are + - / and*

If you look at your answer choices, option d is the only that has an expression as well as the operation, so both things in one equation.

Answer: (1, 2)

Concept:

There are three general ways to solve systems of equations:

Since the question has specific requirements, we are going to use elimination

Solve:

Given expressions

x + 5y = 11

-x + 4y = 7

Add both equations together to elimination [x] variable

(x + 5y) + (-x + 4y) = 11 + 7

x - x + 5y + 4y = 18

9y = 18

Divide 9 on both sides

9y / 9 = 18 / 9

[tex]\boxed{y=2}[/tex]

Find the x value

x + 5y = 11 ⇔ Given equation

x + 5(2) = 11 ⇔ Substitute values of y

x + 10 = 11 ⇔ Simplify by multiplication

x + 10 - 10 = 11 - 10 ⇔ Subtract 10 on both sides

[tex]\boxed{x=1}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer:

Stack the two equations and add them together as if they were multi-digit numbers. That will eliminate the x and then you can solve for the y. Knowing y you can then go back and solve for x.

Step-by-step explanation:

x + 5y = 11

-x + 4y = 7

---------------- "Add" the equations above to get the equation below.

9y = 18

Now you can divide both sides by 9 to see that y is equal to 2.

Now that you know that y = 2 you can substitute y in either of the two original equations. I'll use the first.

x + 5(2)= 11

x + 10 = 11

x = 1

Answer: 2:5

Step-by-step explanation:

To find the ratio, we need to find the greatest common factor and divide both of the dimensions by the greatest common factor. In this case 12 is the greatest common factor.

60/12=5

Therefore, the ration that expresses the scale used to create this dimension is 2:5.
