What is the solution to the following system

of equations?

2x+y=8

-x-3y=-12

A 3y+12

B - 3y+12

C 3y-12

D - 3y-12

A stadium has 50,000 seats. Seats sell for $28 in section A, $16 in section B, and $12 in section C. The number of seats in section A equals the total number of seats in sections B and C.

The length of a rectangle with area 38 in2 depends on its width. Write the formula that describes the length of the rectangle as a function of its width.

How do you solve n/3 - 8 = - 2

The second of two numbers is 3 less than twice the first. Their sum is 42. Find the numbers

Solve for x. - 6x+14<-28 and 3x+28<25

Lesson Review Directions: Solve using the FOIL method. Hint: Watch out for any negative signs and follow rules for signed numbers! 1. (x - 2) (x + 8) 2. (x + 6) (x - 12) 3. (x + 9) (x + 4) 4. (x + 6) (x + 2) 5. (x + 6) (x + 9) 6. (x - 4) (x + 5) 7.

9) A health insurance policy costs $700 per year. plus $15 for each visit to the doctor's office. A different plan costs $560 per year, but each office visit is $50. Find the number of office visits for which the two plans have the same total cost.

Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2y + 4x = 18 2y - 3x = 4 A. (6, - 3) B. (5, - 1) C. (2, 5) D. (3, 3)

What happens to the line if you change the slope a) if y = 2x + 3 and change it to y = 3x + 3 b) if you change the 2 to - 2

If x = 3, calculate the value of: 2x2 + x
