Answer:
3y-4x=9
Step-by-step explanation:
using y-y1/ x- x1=m
y-1/x--3=4/3
y-1/x+3= 4/3
3(y+1)=4(x+3)
3y+3= 4x+12
3y-4x=12-3
3y-4x=9
Answer:
x = 7/2 y = 5/2
Step-by-step explanation:
You can either use the elimiation or adding and subtracting method to get the variables for both x & y.
Once you solved for one variable, plug in the variable you just solved back into the original equation to find the other variable.
Initial velocity = 0 m/s
Acceleration = 9.8 m/s²
Time = 3.1 s
s = ut + 1/2 at²
s = 1/2 x 9.8 x 3.1²
s = 47.1 m
The building is 47.1 meters tall
