Alg2 lesson 8-7
- 1. Solve the system of equations:
x + 2y = 5
y = 3x – 1
x + 2(3x – 1) = 5 y = 3x – 1
x + 6x – 2 = 5 y = 3(1) – 1
7x = 7 y=2
x=1 (1, 2)
- 16. Solve the system of equations.
hyperbola
line
4(4 – 8y + 4y2) – 16y2 = 25
16 – 32y + 16y2 – 16y2 = 25
- 18. Solve the system of equations.
circle y2 = 10 – x2
ellipse if x = 3:
3x2 + 10 – x2 = 28 y2 =10 – (3)2
y2 = 1
2x2 = 18
y= 1
x2 = 9
if x = -3:
x = 3 y2 =10 – (-3)2
y2 = 1
y= 1
Answer: (3, 1), (3, –1) , (–3, 1), and (–3, –1)
