Answer:
19 shows direct variation
20 does not (guessing for this one a bit)
19- Shows a steady increase of four in y for each one in x
20- Shows no increase
Step-by-step explanation:
19 is a constant increase by 4, 20 does not show either
Answer:
x=199 and y=158
Step-by-step
Let x and y be two numbers
Given that the sum of the two numbers is 357, it may be written as
difference of the two numbers is 41, it may be written as
Now adding (1) and (2), we get
_______________________________________
_______________________________________
(Where y is in alternative signs so it may be cancelled)
Therefore
now substituting x=199 in (1) we get
Therefore
y = 4x−10 ; slope m = 4
Parallel has same slope so slope of new line = 4
y = 4x + b
b = y - 4x
Passes through (1, 13)
b = 13 - 4(1)
b = 13 - 4
b = 9
Equation
y = 4x + 9
Answer:
A
Step-by-step explanation:
you always do the first coordinate then you do the next ones. Alwasy move to the left when doing negatives
