Y = -2x + 6....so we sub in -2x + 6 for y in the other equation
3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3
now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0
so ur solution is : (3,0)
Answer:
No solution
Step-by-step explanation:
Because ;
R+74=R-74
R-R=-74-74 —> 0= -148
Or R-R=74+74 —> 0=148
I hope I helped you^_^
Answer:67
Step-by-step explanation: the first one is the best. that’s why
To determine the time it takes for the maximum height to be achieved, derive the equation and equate to zero.
h = -16t² + 112t + 30
dh / dt = 0 = 2(-16)t + 112
The value of t is 3.5 s. Substitute this value of time to the equation for h,
h = -16 x (3.5 s)² + 112 x 3.5 s + 30 = 226 ft
Thus, the answer is letter D.
