For John

This is due this evening, so a prompt response would greatly appreciated!

I require an answer key to some problems.

I need no work showed, just answers so that I ma compare too.

The only exception is graphs, those I would like a picture of.

1) Solve the equation:

2y(y+5)=72

2) The product of two consecutive integers is 11 more than their sum. What are the two numbers?

3) Solve:

V^2=32-4v

4) Decide whether the given ordered pair is a solution of the given system:

(-2,-3)

3x+5y=-21

4x+2y=-14

5) Solve the system of equations by graphing:

8x-6y=36

8x=6y+36

6) Solve using the substitution method

15x-20y=-1

15y=2+5x

7) Solve by elmination

7x-y=18

x+6y=21

8) Solve using the substitution method

15x-20y=-1

10y=-1+15x

9) Solve by the substitution method

7x-y=9

23x+15y=1210

10) A store mixes Brazilian coffee at $10 a kilogram and Turkish coffee at $13 a kilogram. The mixture is set to sell for $12 a kilogram. How much of each will be used to make a 576 kilogram mixture?

11) Factor/Simplify

√28

12) Simplify

66√22/11√2

13) Solve using the quadratic formula

5x^2-3x-7

14) Solve using the quadratic formula

1/6x^2-1/3x=1

15) Graph the quadratic function and give the vertex

y=-2x^2+4

16) Graph the parabola and give the vertex

y=-x^2=2x-3
