Answer:
x=11
Step-by-step explanation:
5x+13=9x-31
subtract 9 from both sides.
-4x+13=-31
you want to isolate the x value so subtract 13 from both sides.
-4x=-44
now divide both sides by -4.
x=11
Answer:
Yes the y value an have more than one x value BUT the x value can only have one y value.
Step-by-step explanation:
example if we have 1 and it goes to 2 the 1 cant go to another number such as 3.. if we had another number like 4 and it goes to 2 like the 1 it would be acceptable
hope this helped and is not to confusing-
Answer:
y = (1/2)x + 1
Step-by-step explanation:
linear line equation is y = mx + b
Where m is the slope and b is the y-intercept when x is 0.
For m, m is change in y(delta y) over change in x(delta x).
We are given two points: (0,1) and (4,3).
m = (y2 - y1)/(x2 - x1) = (3-1)/(4-0) = 2/4 = 1/2
y = (1/2)x + b
Now plug in (0,1) into above equation to find b value.
1 = (1/2)0 + b => b = 1
Final equation is y = (1/2)x + 1
Milo owns 27 action-adventure DVDs.
45 (total) x 0.4 (% of comedies) = 18 (# of comedy DVDs).
45 - 18 = 27 (# of action-adventure DVDs)
Or
100 (total %) - 40 (% of comedies) = 60 (% of action-adventures)
45 (total) x 0.6 (% of action-adventure DVDs) = 27 (# of action-adventure DVDs)
