A: x (isabella)
3x+x=36
b: 3x+x=36
4x=36
x=9
3x=27
c: Joseph is 27 years old.
Answer:
y= -3x-16
Step-by-step explanation:
slope intercept form is written as y=mx+b. m is the slope, and b is the y-intercept. -3=m
we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15. subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).

Answer: She will pay 209.74056 each month
Step-by-step explanation:
firstly our cost of computer software = 2938
now the percentage rate of the finance charge per 18 months will be
finance charge rate per 18 months = (rate/12) * 18 = (19/12) * 18 = 28.5% = 0.285
now we find the finance charge
Finance charge = finance charge rate period * cash price
Finance charge = 0.285 * 2938 = 837.33
now we find the installment price
Installment price = finance charge + cash price
Installment price = 837.33 + 2938 = 3775.33
Installment payment = installment payments/number of payment (months)
Installment payment = 3775.44 / 18 = 209.74056
therefore she will pay a sum of 209.74056 each months.
