What is the quotient for 81/-9, -123 divided by -4, -94/-9, and 65 divided by (-5)

Answer:

The numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]

Step-by-step explanation:

Let x and y be the numbers

According to the statement, "The sum of two number is 18.", first equation will be:

[tex]x+y = 18\ \ \ \ Eqn\ 1[/tex]

And according to "The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14." Second equation will be:

[tex]\frac{4}{7}y-5x = 14[/tex]

Multiplying whole equation by 7

[tex]7*\frac{4}{7}y-7*5x = 7*14\\4y-35x=98\\-35x+4y = 98\ \ \ \ Eqn\ 2[/tex]

From equation 1

[tex]x+y = 18\\y = 18-x[/tex]

Putting this in second equation

[tex]-35x+4(18-x) = 98\\-35x+72-4x= 98\\-39x = 98-72\\-39x = 26\\\frac{-39x}{-39} = \frac{26}{-39}\\x = -\frac{2}{3}[/tex]

Putting x = -2/3 in equation 1

[tex]-\frac{2}{3}+y = 18\\y = 18+\frac{2}{3}\\y = 18\frac{2}{3}[/tex]

Hence, the numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]

Answer:The vertex is

(0,7)

Sometimes we have problems with the easier questions because it's not exactly in the form we're used to. Normally for a quadratic, you would complete the square to find the vertex. But this quadratic is already in vertex or standard form:

f(x)=−(x−0)2+7

Answer:

let x is the smaller number

bigger number is x + 8

The sum of two numbers is 72

so

x + (x+8) = 72

answer

x + (x + 8) = 72

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Two numbers add up to 72

let's assume they r x and y

ome number is 8 more than the other

so it will be x and x+8

Therefore x+x+8=72

The missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

Let the line of best fit is:

y = mx + c

The missing points are:

(7, 11), and (9, 9.8)

The correlation will be negative.

The line of best fit is shown in the picture.

Thus, the missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.

Answer:

$5,030.40

Step-by-step explanation:

The balance outstanding at the end of any month is the due amount after adjusting for interest and loan repayment amount. The amount outstanding can be calculated as:

First month

Due amount = $6,000

Interest at 2% = $6,000*2% = $120

Loan repayment = $600

Reduction in balance = $600 - $120 = $480

Balance remaining = $6,000 - $480 = $5,520

Second month

Due amount = $5,520

Interest at 2% = $5,520*2% = $110.4

Loan repayment = $600

Reduction in balance = $600 - $110.4 = $489.60

Balance remaining = $5,520 - $489.60 = $5030.40

Hence, the balance outstanding at the end of month 2 is $5,030.40

Answer: -x^10y^15m^5

Explanation:

The term -x^2 is the same as -1*x^2

Raising -1 to an odd number power leads to -1. So this is why the answer has the negative out front.

For each of the variable terms, multiply the inner and outer exponents. For example, (x^2)^5 = x^(2*5) = x^10.

The general rule is (a^b)^c = a^(b*c).

For the term 'm', think of it as m^1

Step-by-step explanation:

Answer:

A makes the most sense, you would get rid of Y by multiplying it,it is the opposite of divison, this is because x is already almost by itself. the last step would be to get rid of Y. you would multiply Y to cancel it out on the right side and do the same to the left. this automatically gets rid of B and C,leaving A and D, but D doesnt have the R,so that gets rid of D, leaving A.

Answer:

Step-by-step explanation:1000x.07 70

1700x.07. 119

119+70. 189

The amount of commission earned on a day that she sold $1000 worth of phones and $1700 worth of computers is $189.

The amount Hannah earns in commission on a day that she

sold $p worth of phones and $c worth of computers is 0.07 ( p + c).

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Commission on phones = 7%

Commission on computers = 7%

Now,

Sold phones worth = $1000

Computer sold worth = $1700

Now,

The total commission earned.

= 7/100 x 1000 + 7/100 x 1700

= 70 + 119

= $189

Now,

The total commission earned.

= 7/100 x p + 7/100 x c

= 7/100(p + c)

= 0.07 (p + c)

Thus,

$189 commission was earned.

0.07 ( p + c) commission was earned.

Step-by-step explanation:

Let's assign this "number" the variable n:

8n + 3 = 2

8n = -1

n = -1/8

Step-by-step explanation:

Hey there!

According to the figure;

9v = 31° + 4v + 44° { The exterior angle is equal to the sum of opposite adjacent interior angles}

9v-4v = 44°+31°

5v = 75°

v = 75°/5

Therefore, v= 15°.
