Question

1. y = x + 6
y = 2x (1 point)
(6, 12)
(–12, –6)
(–6, –12)
(2, 4)

Answer 1

For questions 1–3, what is the solution of the system? Use substitution.

Answer 2

x=6
y=12
1 is the ans

Answer 3

2. 3x + 2y = 7
–3x + 11 = y (1 point)

Answer 4

3. 2x – y = –7
4x – y = –4 (1 point)
(–1.5, 4)
(1.5, 10)
(4, –1.5)
(–1.5, –2)

Answer 5

4. –4y + 4 = x
2x + 8y = 8 (1 point)
one solution
two solutions
infinitely many solutions
no solution
5. 6x + 2 = y
3y – 18x = 12 (1 point)
one solution
two solutions
infinitely many solutions
no solution

For questions 4–5, how many solutions does the system have?

Answer 6

2) y=-4
x= 5

Answer 7

3) b
