Answer:

[tex] slope(m) = \frac{3}{2} [/tex]

Step-by-step explanation:

Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):

Where,

[tex] (-14, 3) = (x_1, y_1) [/tex]

[tex] (-12, 6) = (x_2, y_2) [/tex]

Plug in the values

[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]

[tex] m = \frac{3}{2} [/tex]

This is a true statement.

True

Answer:

7/4

Step-by-step explanation:

since 1=4/4

4/4+3/4=7/4

Answer:

x - y = 5

Explanation:

As you can see in the first problem the ration is x to y = 8 to 3. This means for every 8 x values, there are 3 y values. Therefore, x - y should be the same as 8 - 3, which is 5.

Answer:

4/10 or 2/5 of a mile more.

Step-by-step explanation:

Since the denominators are the same, all you have to do is subtract the numerators.

9-5=10.

Therefore, Alisha hiked 2/5 of a mile further than Joseph.

The table for total repayment and interest paid for each loan offer:

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Formula;    Simple Interest(I) =  P × R × T/100

For the 1-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)

                                                               = $37,275

Total interest paid = $37,275 - $35,000

                               = $2,275

For the 5-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest

                            = $35,000 + (0.082 x $35,000 x 5)                

                            = $41,570

Total interest paid = $41,570 - $35,000 = $6,570

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

Answer:

that is$ 160 ok alright jf

Answer:

164

Step-by-step explanation:

Because 12 times 16 minus 18

Answer:

x = 3

y = 6

Step-by-step explanation:

-4x- y = -18

2x + 3y = 24 (Multiply everything by 2)

-4x - y = -18

4x + 6y = 48

5y = 30

y = 6

-4x- y = -18

-4x - 6 = -18

-4x = -12

x = 3

Answer: A) 20.9 ; B) 34years

Step-by-step explanation:

Given the following :

AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23

FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1

A)

MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY

F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]

= 38 + 60 +21 + 88 + 23 = 230

SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11

MEAN(X) = 230 / 11

X = 20.9

B)

WHEN A NEW PLAYER WAS ADDED :

MEAN (X) = 22

Let age of new player = y

Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y

Number of players = 11 + 1 = 12

Mean(x) = sum of ages / number of players

New mean (x) = 22

x = (230 + y) / 12

22 = (230 + y) / 12

Cross multiply

264 = 230 + y

y = 264 - 230

y = 34 years

Answer:

[tex]20[/tex]

Step-by-step explanation:

La función es

[tex]f(x)=-70x^2+2800x-45000[/tex]

Diferenciando con respecto a [tex]x[/tex] obtenemos

[tex]f'(x)=-140x+2800[/tex]

Igualar con cero

[tex]0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20[/tex]

Doble derivada de la función

[tex]f''(x)=-140<0[/tex]

Entonces, la función es máxima cuando el número de unidades vendidas,  [tex]x=20[/tex],

Answer:

Step-by-step explanation:

3m=-3

m=1

Answer:

m = -1

Step-by-step explanation:

3m + 4 = 1

subtract 4 from each side of the equation:

3m + 4 - 4 = 1 - 4

3m = -3

divide both sides by 3:

3m/3 = -3/3

m = -1

Answer: = £135

Step-by-step explanation:

Original price = 100%

Percentage increase = 20%

New price = 100% + 20% = 120%

If 120% = £162

What about 100% = ?

= (100 x 162) ÷ 120

= 16200 ÷ 120

= £135.
