Answer:
y = -1/2x - 1
Step-by-step explanation:
Given equation:
y = 2x - 3
Given point: (x1,y1) = (-8,3)
This is in the form of y = mx + c,
so, m1 = 2
If the lines are perpendicular then the product of their slope will be - 1 i.e.
m1 x m2 = -1
2 x m2 = -1
m2 = -1/2
Now, using one point form formula,
y - y1 = m(x - x1)
or, y - 3 = -1/2( x - (-8))
or, y-3 = -1/2(x + 8)
or, y = -1/2x - 4 + 3
or, y = -1/2x - 1
This is the required equation.
Answer:
600 mph
Step-by-step explanation:
Given that,
Distance covered by ball, d = 5 miles
Time taken, t = 30 seconds
1 second = (1/3600) hour
Speed = distance/time

So, the speed of the ball is 600 mph.
Answer:
Csc(5(pi)/4)
Csc(340 degrees)
Step-by-step explanation:
substitute every x in the equation with (-2)
f(-2)=3*2*(-2) = -12
dunno if I get your equation correctly, pls check how you have written it
