-5 +- sq rt of 21/2
Quadratic formula
A= 1 b= 5 c= 1
-b +- sq rt b^2-4ac /2a
-5 +- sq rt 25-4(1)(1) /2
It just has to equal 90° so that they are parallel so 16x-6=90
16x=96 (add 6 to both sides)
x=6(divide by 16)
Answer:
Derek; by 11600 m.
Step-by-step explanation:
Convert 1.5km into m.
1.5 is 1500m.
1500 * 12 = 18000 m
8 * 800 <= Lucy
6400 m <= Lucy's distance
18000-6400=11600m
The x-axis is defined by the equation y=0x+0. Since we see that our equation and that of the x-axis have the same slope, they will never intersect. So, to answer your question, any equation of the form y=b will have no x-intercept, except y=0, which will have infinitely many intercepts
