Answer:
a. y equals one third times x plus 10
= y = 1/3(x) + 10
Step-by-step explanation:
Let us represent:
Let the original final plan = x
Let the current flight plan = y
The initial time of departure = 4.00pm
Her flight was then delayed for 10 minutes
We are told in the question that:
The current flight plan allows her arrive at her destination three times faster.
This means y= (1/3)x
y = x/3
Hence the equation generated =
y = x/3 +10
y = 1/3(x) + 10
Answer:
l = 626.4/bh
Step-by-step explanation:
A triangular prism have a base that is triangular in shape. The volume of a prism has the volume represented as follows.
volume = Al
where
A = Base area
l = width
Since the base is a triangle the base area will be the area of a triangle. Therefore,
volume of a triangular prism = 1/2bh l
where
b = base of triangle
h = height of triangle
volume = 313.2 ft³
313.2 = 1/2bh l
Make the width(l) subject of the formula
multiply both sides by 2
626.4 = bhl
divide both sides by bh
l = 626.4/bh
l = 626.4/bh
recall l = width

y = kx
8 = -4k
so k = -2
y = -2x
y = -2 (7)
y = -14
13.
y = kx
15 = 6k
so k = 15/6 = 2.5
y = 2.5x
y = 2.5 (7)
y =17.5
14.
y = kx
3 = 9k
so k = 3/9 = 1/3
y = 1/3x
y = 1/3 (7)
y =7/3
15
y = kx
-4 = 4k
so k = -4/4 = -1
y = - x
y = - (7)
y = -7
16.
Yes. y varies directly with x
slope = (3+6)/(2+1) = 9/3 = 3
y = mx + b
-6= 3(-1) + b
b = -6 + 3 = -3
equation y = 3x -3
17.
Yes
slope = (2.5 - 7.5)/(-1+3) = -5/2 = -2.5
y = mx + b
7.5= -2.5(-3) + b
7.5 = 7.5 + b
so b = 0
equation
y = -2.5x
She would need 131 feet
