Y = 2x + 1
y - 1 = 2x
x = y - 1/2
So the math here is 1+1 = 2
Well, 9 billion = 9,000,000,000 so in scientific form it would be 9 x 10^9 To get the exponent, just count the number of zeros, which for 9 billion we have 9
Answer:
see below
Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
<em>Comment on discriminant</em>
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
The answer x = -3/5. hope that helps!
