Given that 3x - 8y = 28 Find y when x = 9
Give your answer as a fraction in its simplest form

y = -1/8

Step-by-step explanation:

substitute 9 in for x in the equation

3(9) - 8y = 28

27 - 8y = 28

-27 from both sides to get

-8y = 1

divide both sides by -8

y = -1/8

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

113.42
