First you have to get the equation into slope/intercept format: y = mx + b
So the slope m = 2, and the y-intercept b = -1.
b tells you where the line intersects the y axis. The slope is rise (vertical distance) over run (horizontal distance). I have attached my best attempt at drawing this without graph paper. The dotted line represents the inequality, and the solution set includes the values above the line which is why it is shaded. Hope this helps!
Critical points is where the derivative (slope) is zero or does not exist. So to do this we have to find the derivative of our function:
So we apply chain rule:
=
Set our first derivative to zero and solve for x:
3(x^2 - 1) * 2x = 0
So we can see that (by plugging in) 0, -1 and 1 makes our solution true
So our critical value is x = 0, x = -1, x = 1
Step-by-step explanation:
OI= 3.2 cm (same as OH)
To find GI, use Pythagoras Theorem (a²+b²= c²)
6.8²+3.2²= 56.48
√56.48= 7.5 cm

Answer:
15
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Given the measure of each = 24°, then
number of sides = 360° ÷ 24° = 15
Because there's one 3 & four 7's .
Because there are two 2's & four 9's
