3x + 2y = -10<br> 5x + y = 9
soldier1979 [14.2K]

Answer:

x=4, y=-11. (4, -11).

Step-by-step explanation:

3x+2y=-10

5x+y=9

--------------

3x+2y=-10

-2(5x+y)=-2(9)

--------------------

3x+2y=-10

-10x-2y=-18

-----------------

-7x=-28

7x=28

x=28/7=4

5(4)+y=9

20+y=9

y=9-20=-11

F(x) = 3x - 2<br><br> f(x) = 0, x=?
podryga [215]

Answer:

2/3 =x

Step-by-step explanation:

f(x) = 3x - 2

Let f(x) =0

0 = 3x-2

Add 2 to each side

2 = 3x-2+2

2 =3x

Divide by 3

2/3 =3x/3

2/3 =x

10. Suppose y varies directly as x, and y = 9 when x = 3/2. Find y when x = 1
pogonyaev

Answer:

y = 6

Step-by-step explanation:

We need to interpret the question

y varies directly as x

y varies x

To equate it, we need to add a constant K

y = K/x

Using the information we are provided with

y = 9

x = 3/2

insert into

y = Kx

9 = K * 3/2

9 = 3K/ 2

3K = 9 *2

3k = 18

To get K, divide through by 3

3K/3 = 18/3

K = 6

Since we've gotten our K = 6

y = Kx

Using the new information

y = ?

x = 1

K = 6

y = 6* 1

y = 6

The new y = 6 , x =1
