Answer:
Your bicycle has 22 gears.
Step-by-step explanation:
The number of gears in the bycicle is the number of combinatiors of a front sprocket and a rear sprocket.
For each front sprocket, there are 11 rear sprockets. There are 2 front sprocts.
So, the number of gears that your bicycle has is
2*11 = 22.

Answer: 
Step-by-step explanation:
When any number has a negative exponent, all the negative exponent is doing is flipping the sides.
When we plug -3 in for x we get 
.
Now just imagine the -3 in fraction form as 
. And all you do now is just flip the sides to get 
And now apply the exponent 2 to the 1 and negative 3.
1 to the power of 2 is just 1
-3 to the power of 2 is 9.
So your answer is
Answer: x=3 y=3
Step-by-step explanation:
Assuming you meant 2x+3y=15 as the first problem. You have to make either both the x’s or both the y’all equal in both equations first. Multiply the second equation by 2 (for x’s) and you’ll get 2x+2y=12. The 2x cancels out so you’re left with 3y=15 and 2y=12. Subtract 2y=12 from 3y=15 and you get y=3.
Repeat to figure out x. Multiple second equation by 3 (for equal y’s) and you get 3x+3y=18. This time the first equation is being subtracted from the second one. (3x+3y=18) - (2x+3y=15). Y’s cancel out and you’re left with (3x=18)-(2x=15. Subtract and you get x=3
Answer:
B and D
Step-by-step explanation:
The g(x) = 725 makes no sense to me....
however g(x) = -2x/(x-3) can be solved by plugging x = value into function
a) g(x) = -2x/(x-3)
g(0) = -2(0)/(0-3) = -3
= 0/-3 = 0 ≠ -3 FALSE
b) g(x) = -2x/(x-3) = 1
g(1) = -2(1)/(1-3) = 1
= -2 / -2 = 1 equals 1 TRUE
c) g(x) = -2x/(x-3)
g(2) = -2(2)/(2-3) < g(4) = -2(4)/(4-3)
= -4 / -1 < -8 / 1
= 4 is greater than - 8 FALSE
d) g(x) = -2x/(x-3) both values were already calcuated
g(1) = -2(1)/(1-3) = 1 < g(2) = -2(2)/(2-3) = 4
1 < 4 TRUE
