Answer:

Step-by-step explanation:

2) When x = 6

x - 2y = 8

6 - 2y = 8

    -2y = 8 - 6

    -2y = 2

       y = 2/-2

     y = -1

Yes, (6, -1) lies on the line.

3) No, (-2 , -3) is not on the line

4) (-2 , -3) is not a solution to this equation because it does not lie on the line.

3x + y = 10<br> x = 2y + 1 <br><br> simplifying
Vinvika [58]

Answer:

y = 1 , x = 3

Step-by-step explanation:

3x + y = 10

x = 2y + 1

3(2y + 1) + y = 10

6y + 3 + y = 10

7y = 7

y = 1

x = 2(1) + 1

x = 3

Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
34kurt

Answer:

16(x + 3)

4(7x + 8y)

w(11 + h)

Step-by-step explanation:

16x + 48

The greatest common factor of 16 and 48 = 16

Hence, expressing 16x + 48 in factored form:

16x + 48 = 16(x + 3)

28x + 32y

Greatest common factor of 28 and 32 = 4

Hence,

28x + 32y = 4(7x + 8y)

11w + hw

11w + hw = w(11 + h)
