Answer:
Y=2x+0.5
Step-by-step explanation:
The gradient is 2/1=2x
The y-intercept looks to be around 0.5
To find net income, find the money mr. hall gained, and subtract how much he loss
Gains:

$48
total: $2992
17,280 - 2992=
$14,288 net income
Answer:
X=-3 y=-8
Step-by-step explanation:
Put the second one in first
The 3 known points of the parabola are the origin (0,0) and the bottom left and right points ( -5,-50) (5,-50)
The general form of a parabola that goes through the origin is:
y = ax^2
We need to solve for a:
-50 = a(5)^2
-50 = 25a
a = -50/25
a = -2
Now the equation of the parabola is y = (-2)x^2.
To solve for the vertical clearance (y) 2 meters from the edge
Subtract the distance from the edge 2 meters from the original edge which is 5 meters, 5-2 = 3.
Now replace x with 3 and solve for y:
y = (-2)3^2
y = -2(9)
y = -18
The clearance would then 50 - 18 = 32 meters.
The answer to the problem is y=-13
