Answer:
Step-by-step explanation:
2y = -4x + 8
y = -2x + 4
perp. 1/2
y - 2 = 1/2(x - 6)
y - 2 = 1/2x - 3
y = 1/2x - 1
Answer:
x = 10
Step-by-step explanation:
l n 20 + l n 5 = 2 l n x
ln (20×5) = ln x²
ln(100) = lnx²
100 = x²
x = +/- 10
Since logs of negative numebrs don't exist, we reject -10
This is the answer the x=3 and the y=2
Set each set of parentheses to 0 and solve for x.
X—6 = 0
X = 6
X + 5 = 0
X = -5
X-9 = 0
X = 9
The zeros are 6, -5, 9
