Answer:
y = -mx - 13.
Step-by-step explanation:
21-y-mx=34
Add y to both sides
21 - mx = 34 + y
Subtract 34 from both sides
-13 - mx = y
Rearrange:
y = -mx - 13.
X²=3x+3
x²-3x-3=0. have to get 0 on right first
identify a,b,c. a is 1, b is -3, c is -3
now plug in to the quadratic formula...
x = -b±√(b²-4*a*c) / 2a
x = -(-3) ± √((-3)²-4*1*(-3)) / (2*1)
x= 3 ± √(9- -12) / 2
x=( 3 ± √21) /2
