Answer:
x ≤5
Step-by-step explanation:
There is a closed circle at 5 so that means equals
The line goes to the left so that means less than
x ≤5
Answer:
haha! You know the answer. Thanks tho!
Step-by-step explanation:
First find the difference of the numerator. to do this multiply 1/x by 2 and 1/2 by x. you should get (2-x)/2x. now moving on to the whole fraction. then multiply the (2-x)/2x by 2x and the (x-2) by 2x. you should get (2-x)/(2x)(x-2). now factor out a negative from the (x-2) at the denominator to get -(2-x). so now you can cancel the (2-x) from the numerator and denominator! the answer will be 1/-2x! :)
Answer:
Step-by-step explanation:
Let football cost be f and basketball cost be b
<u>We have two equations as per given:</u>
- 5f + 14b = 110
- 10f + 6b = 82.50
We need to find b, therefore we'll eliminate f
<u>To do so we'll double the first equation and subtract the second one:</u>
- 2(5f + 14b) - (10f + 6b) = 2(110) - 82.50
- 28b - 6b = 220 - 82.50
- 22b = 137.5
- b = 137.5/22
- b = 6.25
Each basketball costs $6.25
Answer:
-256 +64 - 16 + 4 - 1
Step-by-step explanation:
A series is the summation of all the terms in a sequence.
So it is only the last three options that qualify to be a series.
The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.
The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.
The series -256 +64 - 16 + 4 - 1 has a common ratio of
There the only series that is geometric is.
-256 +64 - 16 + 4 - 1
