Answer: if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Step-by-step explanation:
Here x will represent the number of minutes.
with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.
so if 0 < x ≤ 450, y = $60.
now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:
if 450 < x ; y = $60 + (x - 450min)*$0.35
where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.
So our piecewise function is:
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Answer:
the answer is C
Step-by-step explanation:
the equation is y=mx+b
the b is the starting point which is 25
the m is the slope/rate of change which is 5
as a result Y =5x+25
Answer: 8 times more 8*2 1/2 = 20 pounds.
Step-by-step explanation: If 2.5 pounds cover 1/8 then simply multiply the 2.5 by 8, since you'll need 8/8. 8/8=1.

Answer:
let the larger number be x and smaller number be y
1 equation
x-y=19
or x=19+y
2 equation
x=4y-8
then
putting valu of x in eqn 2nd
19+y=4y-8
19+8=4y-y
27=3y
y=9
so putting value of y in eqn 1
x= 19+9
x=28
therfore, larger number =28
smaller number =9
