elizabeth creates the following system of equations to determine how many apples, a, and oranges, r, she should buy when she goes to the farmer’s market.

3a + 3r = 6
a − r = 4

elizabeth determines that the solution (a, r) to the system of equations that she created is (3, −1). is her solution correct? in context, is her solution viable?

select one:
a. yes, her solution is correct; yes, her solution is viable in context.
b. yes, her solution is correct; no, her solution is not viable in context.
c. no, her solution is incorrect; yes, her solution is viable in context.
d. no, her solution is incorrect; no, her solution is not viable in context.

A.

Step-by-step explanation:

3a+3r=6

a-r=4

+r. +r

a=4+r

3(4+r)+3r=6

12+3r+3r=6

6r=-6

r=-1

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
