1. 3x - 3y = 9
to find the x or y intercept, multiply the other variable that you are not tryng to find by 0
3x - 3(0) = 9 3(0) - 3y = 9
3x = 9 -3y = 9
3x/3 = 9/3 -3y/-3 = 9/-3
x = 3 y = -3
2. I did the same thing for the rest
x = 6 y = -2
3. x = 2.5 y = -5
4. x = -4 y = -2/3
Answer:
17.5 and 5
Step-by-step explanation:
F = 3/r.
The formula for the volume of a cylinder is
V=πr²h. We know that h=2r, so this gives us:
V = πr²(2r) = 2πr³
The surface area of a cylinder is the sum of the areas of all of the faces. The bottom and top are circles, whose areas are both given by A=πr². The lateral area of a cylinder is given by the circumference multiplied by the height. C = 2πr, and the height is 2r, so the lateral area would be
A=(2πr)(2r)= 4πr². This gives us a total surface area of
SA = 4πr²+πr²+πr² = 6πr².
The ratio of surface area to volume would be:
SA/V = 6πr²/2πr³. After simplifying, we have f=3/r.
Answer:
-6m+3-n
Step-by-step explanation:
-3 x 2m = - 6m
-3 x - 1=3
Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
