45 = 3x3x5
Or you could simplify it to 3^2x5
Y=4 because it only has a y-intercept
440 x 10 = 4,400. Yes 4,400 is 10 times as much as 440
Answer:

Step-by-step explanation:
Given data
Total amount for the rent= $500
Cost of food per night= $10
Family charges per night=$60

and let the total charges be y
Hence, the expression for the situation is given as
y=500+10x+60x
y= 500+7x
