<span>We can solve this equation by completing square
and using formula a² -2ab+b² = (a-b)²
x²-3x=-5/4
x² -2*3/2x +(3/2)² = -5/4 +(3/2)²
(x-3/2)²= -5/4 +9/4
</span>(x-3/2)²= 1
√(x-3/2)²= +/-√1
x-3/2 = 1, or x-3/2 = - 1
x=1+3/2=5/2=2.5 or x=-1+3/2= 1/2=0.5
So we got 2 answers
x=2.5 and x= 0.5.
It's the last answer. Think about when you move a point on a graph left 4 spaces it's on the x axis. Because it's going left it's going towards the negative numbers hence minus and not plus. some concept for the y axis.
lateral area = 2 X pi X r X H
= 2 x 3.14 x 5 x 9 = 282.6
Answer:
Step-by-step explanation:
Using the slope formula (y2-y1)/(x2-x1), we get (0 - (-2)/(2-0). Simplified, this gets you (0+2)/(2-0). This is equal to 1, which means the slope is one. Putting this into slope-intercept form (y=mx+b), we can plug in (0, -2), getting us -2=0+b. b is equal to -2 then. Thus, the full equation would be y=x-2
