Answer:

SYSTEM 1

[tex]4x + 3y = 4 - - - eqn(i) \\ - 2x - 3y = - 8 - - - eqn(ii) \\ eqn(i) + eqn(ii) \\ = > 4x - 2x = 4 - 8 \\ 2x = - 4 \\ x = \frac{ - 4}{2} \\ x = - 2 \\ in \: eqn(i) \: \: 4x + 3y = 4 \\ but \: x = - 2 \\ = > 4( - 2) + 3y = 4 \\ = > - 8 + 3y = 4 \\ 3y = 12 \\ y = \frac{12}{3} \\ y = 4[/tex]

SYSTEM 2

[tex]3x + 2y = 7 - - - eqn(i) \\ 2x - y = 7 - - - eqn(ii) \\ multiply \: eqn(ii) \: by \: 2 \\ = > 4x - 2y = 14 - - - eqn(iii) \\ eqn(i) + eqn(iii) \\ = > 7x = 21 \\ x = \frac{21}{7} \\ x = 3 \\ in \: eqn(ii) \: 2x - y = 7 \\ but \: x = 3 \\ hence \: \: 2(3) - y = 7 \\ y = 6 - 7 \\ y = - 1[/tex]

Best repayment option: income-driven repayment.

Step-by-step explanation:

The government offers four income-driven repayment plans: income-based repayment, income-contingent repayment, Pay As You Earn (PAYE) and Revised Pay as You Earn (REPAYE). These options are best if your income is too low to afford the standard payment.

Answer:

The one with the least cost of borrowing

Step-by-step explanation:

Answer:

#7.

The domain is {-3,0,4}

the range is {-5,0,1,7}

not a function

#8

D={3,6,12,18}

R={5,7,9,10}

not a function

Step-by-step explanation:

First, 7.

the domain is the all of the x values, in numerical order, listed once, even if it repeats.

D={-3,0,4} (notice how -3 is listed twice; despite that, we only list it once)  

the range is all of the y values, in numerical order, listed once, even if the numbers repeat

R={-5,0,1,7}

A function can have the range (y values) repeat, however, the domain (x values) cannot repeat.

Therefore, this is not a function, since -3 is listed twice.

For 8.

The domain, can be listed as

D={3,6,12,18}

And the range as

R={5,7,9,10}

Notice how it says that if 6 is the input (x), the output (y) can be 5 or 10. Since we said the domain CANNOT repeat, this isn't a function.

Hope this helps!

Answer:

8

Step-by-step explanation:

This question is incomplete, the complete question is;

In an interval whose length is z seconds, a body moves (32z + 2z²) ft.

What is the average speed v of the body in this interval?

Answer: the average speed v of the body in this interval is 32 + 2z ft/s

Step-by-step explanation:

Given that;

Length of travel = z seconds

also the body moves (32z + 2z²) ft

i.e

distance travelled = (32z + 2z²) ft

average speed v of the body in this interval = ?

Now to get the Average Speed

we simply say;

Average Speed V =  (32z + 2z²) / z

Average Speed V = 32 + 2z ft/s

Therefore the average speed v of the body in this interval is 32 + 2z ft/s

Answer:

it is linear pair

Step-by-step explanation:

it is not complementary because it doesn't add up to a sum of 90°. it is not vertical angles because that would mean they have the same degree. it's linear because they add up to 180°.

Answer:

32

Step-by-step explanation:

You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.

Answer:

[tex]\frac{17}{8}[/tex] or [tex]2\frac{1}{8}[/tex]

Step-by-step explanation:

First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.

[tex]2\frac{1}{2}[/tex][tex]-\frac{3}{8}[/tex]

[tex]\frac{5}{2}[/tex][tex]-\frac{3}{8}[/tex]

Then we will multiply the first term by 4/4 to match the denominator of the second term..

[tex]\frac{5}{2}[/tex] * [tex]\frac{4}{4}[/tex] = [tex]\frac{20}{8}[/tex]

Finally we subtract.

[tex]\frac{20}{8}[/tex][tex]-\frac{3}{8}[/tex] = [tex]\frac{17}{8}[/tex]

The solution of the given fractional expression is 17/8.

A fraction is a numerical quantity that represents a part of a whole or a quotient of two quantities. It consists of a numerator (the top number) and a denominator (the bottom number), separated by a horizontal line.

The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.

First convert the mixed fraction into the whole fraction and solve further to get the final solution.

The given fractional expression will be solved as,

[tex]E = 2\dfrac{1}{2}-\dfrac{3}{8}\\\\E = \dfrac{5}{2}-\dfrac{3}{8}\\\\E = \dfrac{20-3}{8}\\\\E = \dfrac{17}{8}[/tex]

Hence, the solution will be 17/8.

Answer:

1. 13.65, 136.5, 1365    

2. 57.14, 5.714, .5714

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.

1.365 x 10^1 = 13.65

1.365 x 10^2 = 136.5

1.365 x 10^3 = 1365

2.

571.4 / 10^1 = 57.14

571.4 / 10^2 = 5.714

571.4 / 10^3 = 0.5714

3.

479 x 10^(-1) = 4.79 * 10^1 = 47.9

479 x 10^(-2) = 4.79 * 10^0 = 4.79

479 x 10^(-3) = 4.79 * 10^(-1) = 0.479

4.

89.15 x 10^3 = 8.95 * 10^4 = 89500

5.

217.5 / 10^2 = 2.175

6.

I can't see if that is a comma or period, so I will do both

4,000 x 10^(-3) = 4 * 10^(0) = 4

4.000 x 10^(-3) = 4 * 10^(-3) = 0.004

7.

89.25 / 10^1 = 8.925

8.

3.107 x 10^1 = 31.07

9.

45.2 / 10^3 = 0.0452

10.

2,100 x 10^(-2) = 2.1 * 10^1 = 21

11.

5.7 / 10^3 = 0.0057

12.

I can't see if that is a 2 or 3, so I will do both. Standard form refers to the usual way that  numbers are written. Power to the 3 means move the decimal right 3 places, while power to the 2 means move the decimal right 2 places.

The number of bottles of shampoo required to complete the job is, 113

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Area of square = a²

Area of rectangle = a × b

Area of circle  = πr²

Given that,

The dimensions of the room are 200 feet by 180 feet

Each bottle of carpet shampoo can be used to shampoo 320 square feet of carpet

bottles of shampoo  = ?

Total area we need to clean = 200 × 180

                                               =  36000

one bottle can clean area = 320 square feet

number of bottles  = Total area /one bottle can clean

number of bottles  =  36000/320

                               =   112.5

                               ≈ 113 bottles

So, The number of bottles required is 113

No diagram is provided but we can still work it out (it may vary).

So the from the description, we can tell that m∠EGB = m∠FHC through alternate exterior angles.

So,

m∠EGB = 2x + 40

m∠FHC = 3x - 10

m∠EGB = m∠FHC

2x + 40 = 3x - 10

40 = 3x - 2x - 10

40 = x - 10

40 + 10 = x

50 = x

x = 50

The value of x is 50
