Answer:
James
Step-by-step explanation:
James rate:
2x + 2 = 4
2x = 2
x = 1 hour
Rate = distance/time = 4/1 = 4 miles per hour
Craig's rate = 1/2 = 0.5 miles per hour
James is faster
Answer:
discriminant: 241
2 real roots
Step-by-step explanation:
The discriminant is the part of the quadratic equation that is under the sqare root
x=(-b±√(b²-4ac))/2a
discriminant: b²-4ac
We also know that a quadratic equation is in the form ax²+bx+c = 0, so we can plug in the values we know from our equation to find the discriminant.
a=4
b=-17
c=3
(-17)^2-4(4)(3)
We also know that if the discriminant
is positive we have 2 real roots
is 0 we have 1 real root aka a repeated real solution
is negative we have no real roots
So it means every 30 minutes he runs 6 miles
Answer
1: is a parellogram 2: parellogram, square, rectangle
Answer: A
<u>Step-by-step explanation:</u>
The vertical asymptote is the restriction on the x-value. Since the denominator cannot be equal to zero, then x + 1 ≠ 0 → x ≠ -1. So, the vertical asymptote is: x = -1
The horizontal asymptote is the restriction on the y-value. Since the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. However, there is a vertical shift of 2 units up so the horizontal asymptote is: y = 2
The only graph that displays these asymptotes is the first graph, <em>which I call graph A.</em>
