x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
Answer:
First one is the correct answer!!
Step-by-step explanation:
Answer:
pi, the square root 72
Step-by-step explanation:
Answer:
So the slope of this function is
and the y-intercept is 
Step-by-step explanation:
A first order function has the following format:

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.
We have the following equation:

We just have to rewrite this equation



Which means that

So the slope of this function is
and the y-intercept is 
Answer:
K(x) =
( curvature function)
Step-by-step explanation:
considering the Given function
F(x) = 
first Determine the value of F'(x)
F'(x) = 
F'(x) = -10x
next we Determine the value of F"(x)
F"(x) = 
F" (x) = -10
To find the curvature function we have to insert the values above into the given formula
K(x) ![= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%7Cf%22%28x%29%7C%7D%7B%5B1%20%2B%28%20f%27%28x%29%5E2%29%5D%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D%20%7D)
K(x) =
( curvature function)
