Answer:
1. y = 3x - 3
2. y = -2 1/2x + 10
10/-4 = -2 1/2 is the slope
3. undefined
4. y = x - 4
5. y = x - 5
6. 6x + 2y = 4 and -3y = 9x + 12
7. -3x + y = 7, y = 3x + 1, and y =3x
8. y = 2x + 5
9. y = 1/4x - 4
Answer:
6.125 or 49/8
Step-by-step explanation:
1 3/4 times 3 2/4
<span>A) 11c - 2d = -2
B) c + 8d = 8
</span><span>B) c = 8 - 8d then substitute this into A)
</span><span>A) 88 -88d - 2d = -2
A) 90 = 90d
d = 1
c = 0
</span>
