Plug the y value in for y and plug the x value in for x
> less than
<u>></u> less than or equal to
Example:
(4,5)
y > 5y <u>></u> x
5 > 5x5 <u>></u> 4 = 5 > 25 <u>></u> 4 = false
they all should be false
if one had to be correct, I would say (0, 0)
2x^2-7=4
subtract 4 from both sdies
2x^2-11=0
therefor
2x^2=11
divide by 2
x^2=5.5
square root both sdies
x=-2.345 or 2.345

Hello!
I've attached the diagram.
For this problem, since you have a right triangle, you can use the Pythagorean Theorem to fine the length of the ladder (the hypotenuse of the triangle).
Pythagorean Theorem (where c is the hypotenuse):
a² + b² = c²
The triangle's leg lengths are 8 and 6; substitute into the theorem:
8² + 6² = c²
Simplify:
64 + 36 = c²
100 = c²
10 = c
Answer:
The length of the ladder is 10 m.
The derivative of (x+1)^2, for this you use the chain rule, to get 2x+2.
