Answer:
x<1.912931
Step-by-step explanation:
Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.
X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2
X = [1 +/- sqrt(97)]/2
Step-by-step explanation:
Answer:

Step-by-step explanation:
<u>Step 1: Subtract 21 from both sides</u>



<u>Step 2: Divide 8 from both sides</u>



Answer:

Answer:
y=1
Step-by-step explanation:
the "mx" part of the equation is the slope, since we need the slope to be zero, there won't be anything in the "mx" part. The "+b" bart of the equation is the y-intercept, since we need the y-intercept to be one, the "+b" part will be 1.
