You would draw a dot going over 1 on the x-axis and go down 2 on the y-axis. Make a dotted line then put 0,0 in fo y and x. If it's true shade over the part where (0,0) is located, if it's false shade on the opposite side.

drwls i right. The answer would be 15:41

thats sounds good.

y=2-x or y= -x+2 its the same thing

its a positive eight because -2 to the power of two gives you a postive four then, when you multiply across you get (1/2)(4)(4) which equals eight

oops i double checked my answer and chopsticks is right, its y=-1/3x+2

but to correct you, you are able to switch them around 2+3=5 and 3+2=5 its the same thing -1/3 is the slope and 2 is the intercept

I guess it depends on the teacher mine doesnt care which way you put it because its both the same thing when you graph it out

y=4x+3 then plug it into the other equation 9x+3(4x+3)=21 9x+12x+9=21 21x+9=21 21x=12 x=12/21 then plug that into the original equation to find y

x^2+x-2=0 x=1 is your discontinuity

because having 0 in the denominator would make your function be undefined and therefore be a discontinuity at that point. If you set the denominator equal to 0 and solve your answer would be 1. x^2+x-2=0 (1)^2 + 1 - 2=0 1+1-2=0
