Answer:
(2, 0)
(0, -2)
Step-by-step explanation:
A linear function has the form y = Ax + B
where A is the slope, and B is the y intercept
we are told the slope is 1,
y = (1)x + B
now we can plug in the x and y from the known point
2 = 4 + B
B = -2 so the y intercept is (0, -2)
y = x - 2 is the function
The zero occurs when y = 0
0 = x - 2
x = 2 so the zero is (2, 0)
The solution of system is x=14, y=37
Step-by-step explanation:
Given equations are:
-4y = -64 - 6x => 6x-4y=-64 Eqn 1
4x - 4y = -36 Eqn 2
Subtracting equation 2 from eqn 1
The solution of system is x=14, y=37

Answer:
20 seconds
Step-by-step explanation:
roots are (0,0) and (20,0) so 20-0 will provide the time from takeoff to landing
No. -3=2(4)+1 simplifies down to -3=9 and that is not true
