X = 3 and x = -1 are the answers for both. They are exactly the same equation.
FOR COMPLETING THE SQUARE
Make in terms of ()^2 which you can do by adding numbers to both sides. Eventually it will look like this:
(2x - 1)^2 - 7 = 0
Add to both sides, take a square root and then solve.
USE THE QUADRATIC FORMULA
Be sure to solve for zero and be aware of negatives when plugging in.
Answer:
6.71
Step-by-step explanation:
Use the Pythagorean Theorem with the triangle:
6^2 + 3^2 = x^2
x = 6.71
Answer:
45 %
Step-by-step explanation:
8 - 20 will get you across IF it is NOT a prime
primes in this range are 11 13 17 19
8-20 is 13 chances minus the four primes leaves 9 rolls out of a possible 20 rolls that will get you across
9/20 = 45%
Answer:
Top box: Endpoint
Bottom box: Ray
Step-by-step explanation:
Assuming that the top box is supposed to be for the point shared by both rays, then it is a endpoint of the rays, as the lines do not continue past the point on the opposite side.
The bottom box will then be a ray, as no point is shown, and a arrow is used at the "end" of the line to signify that it will continue on <em>forever</em>.
