Does the point (2,-1) lie on the line
y=3-2x?

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b

the scale is 1/9 my friend can't simplify 1 anymore so it will be (for every 1 there's 9)

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
