heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
Answer:
H. x = 1 , slope is undefined
Step-by-step explanation:
The slope of a vertical line is always undefined.
If you think about it, no matter what y value you use, the x will always be 1 (In this equation). Such as:
(1, 5)
(1, 8)
(1, -12914)
(1, 272)
With x always being one, it forms a vertical line parallel to the y-axis
An arithmetic sequence (a_n) is as follows:
where
is the first term and d is the constant difference,
thus, we see that the n'th term of an arithmetic sequence is
in our particular case d=5, the third term is 8, so we have:
and the general term is
,
Answer: first term is -2, n'th term is -2+5(n-1)
X = -1/15y+7/3
