So it would be,
y = 72 - 4x
y is the total money that is left on the account and x isthe movies rented. after renting 4 movies it would be,
y = 72 - 4(4)
y = 72 - 16
y = 56
So there are $56 left in the account after renting 4 movies.
Hmmm… I wish I could help you with this one, sorry
Answer:
radius= 14
Step-by-step explanation:
the distance around the edge is given by = 2πr
88= 2 (22/7)*r⇒ r= 88*7/44= 14
Two lines in a plane can intersect,overlap or be parallel.When two lines intersect they have a common point which lies on both line.This is called solution of the two simultaneous equation which when graphed represent straight lines. Adding the two equations uses Elimination method to solve for x and y. The x and y value obtained is the common point lying on both the lines.
2x - 3y = 1
+ 2x + 3y = 2
4x =3 Or x=3/4
Substituting x value in any of the two-equation we can find the corresponding y value .
2x-3y=1
2(3/4) - 3y =1
Solving for y
y= 1/6
The point of intersection of the two lines is ( 3/4, 1/6)

No because if a number is a whole number then it is also a rational number and an integer
