What is the solution set for this linear-quadratic system of equations?

y= x2 - x-12

y-x-3 = 0

A. {(-3,0), (0,3)}

B. {(-3,0), (4, 0);

C. {(-3,0), (5,8)}

D. {(4,0), (0,3)}

C

Step-by-step explanation:

Given:

To find: solution set for this linear-quadratic system of equations

Solution:

A linear equation is an equation whose degree is 1 and degree of quadratic equation is 2.

Put in

For x = -3, y = -3+3=0

For x = 5, y = 5 + 3 = 8

So solutions are

Option C. is correct

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.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
