Answer: C
Step-by-step explanation:
Simplify to 4x^2 + 12x + 5 = 0 so that all the terms are on one side.
Do a part of the quadratic formula to see.
You only need to do the 
part. If it is negative, that means there are irrational solutions. If it is positive, it has two solutions. If it is 0, it has 1 solution.
It is positive so it has two solutions.
Answer:
w=√200 (or 14.14)
y=20
yea pretty simple its just the Pythagorean theorem and the fact that a triangle with equal base angles is isosceles triangle
Answer:
1. Total distance
2. Shortest time taken
Step-by-step explanation:
Since it is a competition the distance will be the same for all participants.
therefore the information need is
1. The total distance of the competition
2. The time taken by each participant to complete the race
The winning speed is the speed is given as the distance covered in the shortest possible time.
hence the winning speed is expressed as
winning speed= distance/short time taken
Answer:
According to transitive Property of equality : If a =b and b = c then a = c
In this problem you are given with 2 equations:
h(x) = - 2x + 5 ---- 1
h(x) = 3 ------ 2
Apply transitive Property of equality to equation 1 and 2
- 2x + 5 = 3 Now solve for x.
-2x + 5 - 5 = 3 – 5 subtract 5 on both sides.
-2x = -2
(-2x)/(-2) = (-2) / (-2) Divide with -2 on both sides.
X = 1
Step-by-step explanation: I hope this helps.
