Solve algebraically 1. y = x^2+ 3x - 5
y = x + 3

2. y = x^2- 4x + 6
y = x + 2

3. y = x^2- 10x + 14
y = 7x - 16

4. y = x^2-24
y = x - 12

5. y = x^2- 8x + 28
y = 4x + 8

Atest consists of 10 multiple choice questions, each with 5 possible answers, one of which is correct. to pass the test a student must get 60% or better on the test. if a student randomly guesses, what is the probability that the student will pass the test?
