Answer:
the solution is (-3, -2)
Step-by-step explanation:
Please, separate your equations with a (;) or a (.). Better yet, write only one equation per line:
y=2x+4
3x−6y=3
Substitute 2x + 4 for y in the second equation:
3x - 6(2x + 4) = 3, or
3x - 12x - 24 = 3
Combining like terms, we get -9x = 27, and so x = -27/9, or x = -3.
Since we know that y=2x+4, we replace x in this equation with -3 and calculate y:
y = 2(-3) + 4 = -2
Then the solution is (-3, -2).
Answer:
add otherwise I don't know sorry im on that question
Step-by-step explanation:
Answer:
simple, divide the number by two, round as needed. 6=3x as normal, 5=2.5x as nromal, etc.
Step-by-step explanation:
<span> s = -16t^2 + 64t + 3
v = -32t + 64
the maximum height occurs when v = 0:
-32t + 64 = 0 when t = 2 sec
the maximum height is
s = -16(2^2) + 64(2) + 3 = 67 ft
the range is [ 3, 67] </span>
