Answer:
You're right
Step-by-step explanation:
Pythagorean Theorem
Answer:
y = -1x + 4
Step-by-step explanation:
equation for one is y = -1x + 5 simple going back from point (5,-2) gave me a b of 4 so yess
Answer:
14 blue
Step-by-step explanation:
3/2 = 21/b
3b = 42
b = 42/3
b = 14
Answer:
Step-by-step explanation:
Paul ran a 26 1/5 mile marathon in 2 3/4 hours
<u>Paul's average speed was:</u>
- distance/time =
- 26 1/5 : 2 3/4 =
- 131/5 : 11/4 =
- 131/5 * 4/11 =
- 524/55 =
- 9 29/55 mph
<u>Inequality for the speed of faster runners:</u>
Answer: 
On a keyboard you would type sqrt(41)

A slight alternative is to plot the point M(2,-5) to form right triangle LMN. The 90 degree angle is at point M.
The legs are of length LM = 4 and MN = 5, which are found by subtracting the x coordinates together and the y coordinates together (or you can count the spaces). From there, use the Pythagorean theorem to get the hypotenuse LN.
The distance formula is an altered version of the Pythagorean theorem.
