Answer:
A. y=-1/3x+10
Step-by-step explanation:
Perpendicular gradients(slopes) are negative reciprocals so
m=-1/3 then use the point (6,8) to find the equation of the line
y=mx+b
8=(-1/3)(6)+b
8=-2+b
b=10
y=-1/3x+10
The answer is 0 because if you substitute x with 1 and solve the equation you get 0
Answer:
i think it is B and E
Step-by-step explanation:
Step-by-step explanation:
The displacement of a particle d (in km) as a function of time t (in hours) is given by :
Displacement at t = 4 hours,
Velocity of particle is given by :
Velocity at t = 4 hours,
Acceleration of the particle is given by :
At t = 4 hours,
Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.
The picture in the attached figure
we know that
the equation of a line <span>that has a slope of 3 and a y-intercept at (0, 0) is
y-y1=m*(x-x1)
y-0=3*(x-0)------> y=3x
case a) Line AB
m=0
case b) Line CD
C (-3,0) D(3,2)
slope m=(2-0)/(3+3)-----> m=2/6------> m=1/3
case c) Line FG
slope is negative
case d) Line HJ
H( -1,-4) J(1,2)
slope m=(2+4)/(1+1)-----> m=6/2-----> m=3
this is the solution because parallel lines are the same slope
the answer isLine HJ</span>
