Midterm Review - Ch. 1, 2,3

Solve each equation.

1. 8(–12y + 10) = 92 – 6(16y + 2) 2. 7x + 3 = 2(x – 1) 3. 10

4. 9 5

3 x 5. 4t – 12 = –t + 11 6. 6x – 10 – (x + 5) = 0

7. What is the slope of the line whose equation is 4x – 5y = 10?

8. What is the slope of the line passing through (2, 6) and (-9, 8)?

9. For which pair of equations are the lines perpendicular?

A. 2x – y = 1 and xy 2

1 B. 6x + 3y = 10 and 3x – 6y = 10

C. y = 5x and y = -5x D. 3x + 2y = 1 and 2y = 3x + 8

10. For which pair of equations are the lines parallel?

A. y – 5 =3x and 2y – 6x = –12 B. 5x + 3y = 15 and 3x + 3y = 15

Find the equation of the line in any form satisfying the following conditions.

11. Passes through ( 2 , 6 ) and is parallel 12. m = 0 passes through ( 1 , -8 )

to -5x + 2y = 7

13. Passes through ( -1 , 2 ) and ( -5 , -3 ) 14. Passes through ( 0 , 4 ) and is perpendicular to y = 6x - 7

Solve by these systems by graphing by hand (please sketch graph).

15. –2x + y = –7 16. x + 4y = 4

3x – 4y = 8 y = - 4

1 x + 5

Solve by substitution

17. 2x – y = –1 18. 5x + 3y = 8 19. x + 2y = 12

y + x = 4 5x + y = 16 4x + 8y = -19

Solve by elimination 20. x – y = 7 21. 5x – 7y = –2

2x + y = 5 3x + 2y = 36

22. For which system are there infinitely many solutions?

A. 3x + 5y = 7 B. x – 5y = 7 C. 3x – y = 8 D. 2x – y = 1 6x + 10y = 14 2x = 10y + 15 3x + y = 10 y = 2x – 3

Define TWO variables, write TWO equations and solve by substitution or elimination. Show all work for full credit!

23. The sum of two numbers is 106. One number is five less than twice the other.

What are the two numbers?

24. At McDonald’s, 2 burgers and 2 fries cost $5.50. If you order 3 burgers and 4 fries it cost $9.25.

How much does one burger cost? One order of fries?

25. The perimeter of a rectangular garden is 168 ft. The length of the garden is 30 more than 5 times the width.

What are the dimensions of the garden? (You must have two equations!)

26. Ticketmaster sells pavilion and lawn tickets to Pine Knob. A total of 5,000 tickets were sold for a concert. The

pavilion tickets cost $20 each and the lawn tickets cost $15 each. The sales for all tickets totaled $82,500. How many of

each type of ticket were sold?
