Paralell has same slope
y=mx+b
m=slope
y=5x-1
when is the slope 5?
take the derivitive of 2e^x
f'(2e^x)=2f'(e^x)=2e^x
that is the slope
5=2e^x
divide both sides by 2
2.5=e^x
take the ln of both sides
ln2.5=x
when x=ln2.5 they are paralell
i think the answer is x ≤ -8
Answer:
D
Step-by-step explanation:
Answer:
6) y = -7x +11
8) y = -1/3x -1
10) y = 5/4x -2
Step-by-step explanation:
It is convenient to start with a point-slope form of the equation.
y = m(x -h) +k . . . . . line with slope m through point (h, k)
__
6) m = -7, (h, k) = (2, -3)
y = -7(x -2) -3 = -7x +14 -3
y = -7x +11
__
8) m = -1/3, (h, k) = (-3, 0)
y = (-1/3)(x -(-3)) +0
y = -1/3x -1
__
10) m = 5/4, (h, k) = (4, 3)
y = 5/4(x -4) +3 = 5/4x -5 +3
y = 5/4x -2
