Answer:

Step-by-step explanation:

-7x-2y=-13

x-2y=11

(subtract the first inequality from the second)

-7x-x = -8x

-2y-(-2y) = 0

-13-11= -24

-8x=-24

x=3

(now place the x value into the second inequality)

3-2y=11

-2y=11-3

-2y=8

y=-4

x=3

y=-4

Answer: x=3, y= -4

Steps: The two equations are," -7x-2y=-13 " and " x - 2y = 11 "

Let's take the 2nd equation and find for x

x - 2y = 11

x= 11 + 2y

Now place the value of x in the first equation:

-7(11+2y) - 2y = -13

-77 - 14y - 2y = -13

- 16y= -13 + 77

y= 64/-16

y= -4

Now that you found the value of y, place it again on the 2nd equation:

x - 2(-4) =11

x + 8= 11

x=11-8

x= 3

POSSIBLE POINTS. 1

erastova [34]

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

where

a and b are the legs

and

c is the hypotenuse

the problem gives the "legs" because the LONGEST leg is always the hypotenuse.

a^2 + b^2 = c^2

1071^2 + 1840^2 = c^2

1147041 + 3385600 = c^2

4532641 = c^2

You purchase 5 pounds of apples and 2 pounds of oranges for $9.Your friend purchases 5 pounds of apples and 6 pounds of oranges

babymother [125]

Answer:

x = 1 and y = 2

Step-by-step explanation:

Let apples are represented by x

and let oranges are represented by y

You purchase 5 pounds of apples and 2 pounds of oranges for $9. This line in equation format can be written as:

5x + 2y = 9

Your friend purchases 5 pounds of apples and 6 pounds of oranges for $17.

This line in equation format can be written as:

5x + 6y = 17

Now we have two equations:

5x + 2y = 9 -> eq (i)

5x + 6y = 17 -> eq(ii)

We can solve these equations to find the value of x and y.

Subtracting eq(i) from eq(ii)

5x + 6y = 17

5x + 2y = 9

- - -

_________

0+4y= 8

=> 4y = 8

y= 8/4

y = 2

Now, putting value of y in eq (i)

5x + 2y = 9

5x +2(2) = 9

5x +4 = 9

5x = 9-4

5x = 5

x = 1

so, x = 1 and y = 2
