Answer:
-11.
Step-by-step explanation:
f(x) = √(3 - 2x), x ≤ 3/2
let y = √(3 - 2x)
y^2 = 3 - 2x
2x = 3 - y^2
x = (3 - y^2)/2
So f-1(x) = (3 - x^2)/2
f-1(x) = (3 - 5^2) / 2 = -11.
The number of angles equal the number of sides
The number of angles calculate: (n-2)x180°
(n-2)x180°=2700° |divide both sides by 180°
n-2=15 |add 2 to both siedes
n=13
Answer: 13 sides.
Answer:
y-intercept = -3
another point on the line = (6,-1)
Step-by-step explanation:
1. Underline important parts of the question (slope of 1/3, point (3, -2))
2. mark the point that is given (3, -2)
3. slope form is rise over run which basically means that the number one is how much the line rises, and the number three is how much the line goes to the right (since the slope is positive then it runs to the right, if it was negative it would go to the left.) Basically 1/3 = rise over run
4. put your pencil on the point (3, -2) and go up one point and over three points. continue doing so from each new point (two or three points is good enough)
5. take a ruler and draw a line that connects all three and keep it going until it crosses the y- axis (which is the vertical line)
6. the point that crosses through the y -axis is the y-intercept.
7. now you can go and look at your points that you have made and choose one of them to answer the question with
(I hope this cleared it up a bit I'm not very good at explaining things this is the best I can do)
