Answer:

14)   C (-2, 4)

15)   D (-3, -3)

Step-by-step explanation:

-6x + 4y = 28

6x + 9y = 24

-6x + 4y = 28

4y = 28 + 6x

y = 7 + 1.5x

6x + 9y = 24

6x + 9(7 + 1.5x) = 24

6x + 63 + 13.5x = 24

19.5x + 63 = 24

19.5x = -39

x = -2

-6x + 4y = 28

-6(-2) + 4y = 28

12 + 4y = 28

4y = 16

y = 4

____________

4x - 4y = 0

-4x + 3y = 3

4x - 4y = 0

4x = 4y

x = y

-4x + 3y = 3

-4(y) + 3y = 3

-4y + 3y = 3

-1y = 3

y = -3

4x - 4y = 0

4x - 4(-3) = 0

4x + 12 = 0

4x = -12

x = -3

Ad libitum [116K]

Answer:

12%

Step-by-step explanation:

let x represent the actual number of members last year.

current members = 675 and with an increment of 13% over previous year

to find the increment

(675 - x) / x = 0.13

675 - x = 0.13x

collect the like terms

675 = 0.13x + x

675 = 1.13 x

x = approx 597 members were there last year

its hope to increase by the same number next year

percent increase = 675 - 597 / 675 = 78 / 675 = 0.12 = 12%

DochEvi [55]

Answer:

700 miles

Step-by-step explanation:

Given:

Scale of the map is \frac{1}{2}\textrm{ in}=50\textrm{ mi}

∴ 1\textrm{ in}= \frac{50}{\frac{1}{2}}=50\times 2=100\textrm{ mi}

Distance of Susan from mount Shasha on the map is 7 inch.

Therefore, Number of miles = 7\times 100=700\textrm{ mi}

Hence, Susan must travel 700 miles to reach her destination.
