Answer:
(A) y - x
Step-by-step explanation:
Finding a:
- ax + x² = y² - ay
- ax + ay = y² - x²
- a(x+y)= (y+x)(y-x)
- a = y - x
Correct choice is (A)
Answer:
B
Step-by-step explanation:
A constant rate of change refers to a pattern/slope that is unchanging. On a graph, these rate of changes are usually represented by a straight line, and B is the only graph in the question with such a line.
We have been given a table of data that represents the distances traveled by three bicycle riders and time spent on their rides.
To find sum of distances traveled by three riders at the same rate, we will have to find unit rate at which each rider is cycling.
Let us find Loribeth's unit rate of cycling.
Let us find Ira's unit rate of cycling.
Let us convert 3.5 hours in minutes.
3.5 hours = 3 hours+50 minutes=(3*60+50) minutes =230 minutes.
Now let us add rates of our three cycles and then multiply the sum by 230 minutes to find distance traveled by three riders altogether.
Therefore, three riders will travel 101.857 miles while travelling altogether.
Answer:
n = 1
Step-by-step explanation:
Due to it being compounded semiannually, the total amount after n years should be 2000[1+(.086/2)]^2n = 3178. (A = p(1+r/n)^nt)
Hence, solving this equation:
(1+0.43)^2n = 3178/2000
1.43^2n = 1.589
2n = 2
n = 1
