While sitting in class you overheard one of your classmates say, "This equation has infinite solutions, because when I put it in Desmos it gave me parallel lines so I know it makes a conditional equation." Realizing that the student is incorrect, what would you say to help your classmate get their facts straight?

Answer:

The answer is -2, -8.

Step-by-step explanation:

Since the three coordinates of the vertices are A(-5,–8), B(-5,0), and C(-2,0), the fourth vertices of the rectangle will be D(-2, -8)

It is described as a type of two-dimensional geometry where the angle between neighboring sides is 90 degrees. A quadrilateral of that kind is it. in two-dimensional planning geometry, the space occupied by the rectangle.

The following formula may be used to determine the area of a rectangle:

​Rectangle area = length x width

It is given that the three coordinates of the rectangle are A(-5,–8), B(-5,0), and C(-2,0).

We have to find the fourth vertices coordinates of the rectangle will be D(-2, -8)

Let the fourth vertices coordinates of the rectangle will be (x,y).

Since the parallel side of the rectangle is the same. Plotting the graph we will obtain the coordinates of the D.

Thus, the fourth vertices of the rectangle will be D(-2, -8)

Answer:

[tex]A\approx\$880.68[/tex]

Step-by-step explanation:

So, we know that Jolene bought an initial $750.

We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.

So, we can use the compound interest formula, which is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.

So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:

[tex]A=750(1+0.055)^t[/tex]

Add:

[tex]A=750(1.055)^t[/tex]

Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:

[tex]A=750(1.055)^3[/tex]

Evaluate. Use a calculator:

[tex]A\approx\$880.68[/tex]

And we're done!

Formula: A = P(1 + r/n)^t

We have these variables:

P = 750

r/n = 0.055

t = 3

Substitute and simplify:

A = 750(1 + 0.055)^3

A = 750(1.055)^3

A = 880.68

Best of Luck!

I remember doing the last question.

If you recall, x = 29

Just plug 29 into x for each angle

A = 3(29) = 87

B = 2(29) + 1 = 59

C = 29 + 5 = 34

Answer:

The value of angle C is 34°

Step-by-step explanation:

2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}

or, 6x + 6° = 180°

or, 6x = 180° - 6°

or, x = 174°/6

or, x = 29°

now,

value of angle C = x+5°

= 29°+5°

= 34°

Cost of each slice = $2.25 per slice

Number of slices = x

Find:

Equation

Computation:

Total amount spend = Cost of each slice × Number of slices

36 = 2.25(x)

Answer:

Step-by-step explanation:

Answer:

1.) $54

2.) $21 left

3.) 15 tigers

Step-by-step explanation:

1.) If the original price of an item was $60, and it was reduced by 10%, that means it is now being sold at 90% of its original value.

To find out the new price, simply take the original value and multiply it by 90% (as a decimal).

60*.90=54

So the new price is $54

2.) This is simple subtraction. If you spend $45 on some CDs and $12 on a t-shirt, you spent a total of $57. Subtract $57 from your total of $78.

78-57=21

You are left with $21

3.) Ratios are all about multiplication. If the ratio of lions to tigers is 3:5, that means that the number of lions is going to be any factor of 3, as long as it corresponds to the same factor of 5 for the tigers.

For example, if there are 9 lions, there must be 15 tigers.

3*3=9

5*3=15

There are 15 tigers

Step-by-step explanation:

6x  + 5x+2 + 134 = 180               All triangles have 3 angles = 180. Combine

11x + 136 = 180                            Subtract 136

11x = 180 - 136

11x = 44                                       Divide by 11

x = 44/11          

x = 4

=======================

Angles are

5x + 2 = 22

6x   =     24

<3    =    134

Total =  180

Answer:

L = 2w  134 = 2L + 2w

l= length

w=width

l=2w

P=Perimeter= 134 ft

P= 2(l+w)

 = 2(2w+w)

 = 2(3w) = 6w=134

w=134/6=22 1/3 ft

l= 2w = 2 x 22 1/3 = 44 2/3 ft

The complete question is in the picture, please refer to the attached picture.

It is given that:

The expression:

= 2d + 4d - 9 - 7

Plug d = 5 in the above expression:

= 2(5) + 4(5)- 9 - 7

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= 10 + 20 - 9 -7

= 30 - 16

= 14

Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

Answer:

5.603 ounces

Step-by-step explanation:

From the information given, you know the ounces of orange juice included in a bottle and the ounces of mixed fruit juice that the bottle has. So, to be able to determine how much of the bottle of mixed fruit juice is not orange juice​, you have to subtract the ounces of orange juice in the bottle from the ounces of mixed fruit juice that it has:

6.85-1.247=5.603

According to this, the answer is that the bottle of mixed fruit juice has 5.603 ounces that are not of orange juice.
