Serena has a dog washing company that charges a monthly fee of $16 plus $4 per wash. Rama also has a dog washing company that charges a monthly fee of $10 plus $6 per wash. At how many washes do both companies charge the same amount?

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

a 90 degree rotation across the the origin followed by a reflection across the x-axis.

step-by-step explanation:

55 because 55 + 55 = 110 good luck babe

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
