Answer:
(0, -3)
(-1, -10)
Step-by-step explanation:
First we need to find the slope of the given line. And for that we need to bring the equation in y=mx +b form where m is the slope. And for that, we need to solve the given equation for y.
0.5x-5y=9
Moving 9 to the left side
0.5x-5y-9=0
Moving 5y to the right side
0.5x -9 = 5y
Getting rid of 5 by dividing both sides by 5, that is
0.1x -(9/5)=y
or y=0.1x -(9/5)
Therefore slope of the given line is 0.1 and parallel lines have same slopes. Therefore slope of the parallel line is 0.1 too .
For a geometric progression
a, b, c, d
there is a common ratio r equal to:
r = b/a = c/b = d/c
Let the missing number be x
r = x/50 = 450 /x
x² = 22500
x = 150
Answer: 577.50/8.75=X
X= 66

Hope I helped :)
Step-by-step explanation: I divided 577.50 by 8.75 to get my answer.
Divide 455 by 65 and get 7 multiply it by 4 and get 28. 28 dvds will be given away.
