If the crew members used 3 gal of paint per hour and bought 30 gal of paint for a job, then they will work 30:3=10 hours.
- They start at x=0 hours with y=30 gal of paint;
- They end at x=10 hours with y=0 gal of paint (they worked until they used all the paint).
- The dependence between x and y is linear.
Conclusion: the only possible sketch is A.
Answer: correct choice is A.
Answer:
13 and 15
Step-by-step explanation:
the equation is x+2y=43
i just guess and checked till i got to the right answer
so, x=13 and y=15
13+2(15) . it equals 43
Answer:
11
Step-by-step explanation:
The median is the middle value when all of the numbers are put in order from smallest to largest
6, 7, 10, 11,13,13,15
There are seven numbers so the middle number is 4
(3 on the left and 3 on the right)
The median is 11
Answer:
see below
Step-by-step explanation:
Cost for 5 pounds of apples:
($4.25 * 5 pounds) - $2 coupon
21.25 - 2
19.25
Cost of apples with p pounds: 4.25p
If one pound was purchase: 4.25p = 4.25(1) = 4.25
The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.
By inspection, we see that the fourth answer choice satisfies that, as 
Why not the first? We have 
The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute 
The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as
