Answer:
a. 2x - 5y = 3
-5y = 3 - 2x
y = ( 3 - 2x ) / -5
slope = -2 / -5
slope for a. = 2/5
and in the sane way we find slope for b.
Let's solve your equation step-by-step.
x2−4x+3=0
Step 1: Factor left side of equation.
(x−1)(x−3)=0
Step 2: Set factors equal to 0.
x-1=0 or x-3=0
For this one add one on both sides
x−1+1=0+1 x=1
For this one add 3 on both sides
x−3+3=0+3. x=3
x=1 or x=3
<span> y^2 = (3x + 1)^3 / 9x + 2
2*y*(dy/dx)=(9</span>(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ ((9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ (2*y*(9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(6x + 1))/ (2*y*(9x + 2)^2)
answer
A
If v = 15 km/h We have:
d1 = 30 km
d2 = 17 km
Since speed = distance/time follows time = distance/speed.
The total time of the entire trip is is the sum of the time of the first 30 km and the time of the remaining 17 km:
d1/v + d2/(v + 2) = 30/15 + 17/(15 + 2) = 2 + 1 = 3 hours
The answer is t=3hours
