Well the y=mx+b equation for your question is -2x-6 so if you plug 6 in for x, then you will get -2(6)-6, and when you simplify that it is -18.
So k=-18
Answer:
6/x = 3/28.
Step-by-step explanation:
Both fractions are inverted.
Taking the reciprocals:
1 /x/6 = 6/x and
1 / 28/3 = 3/28.
Answer:
(3,6)
Step-by-step explanation:
Y=X+3
Y=X2
X+3=2X
X-2X= -3
-x=-3
x=3
then Y=2X
Y=2×3
Y=6
(3,6)
Answer:
125feet
Step-by-step explanation:
Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.
The arrow reaches the maximum height at dh/dt = 0
dh/dt = -32t + 80
0= -32t+80
32t = 80
t = 80/32
t = 2.5secs
substitute t = 2.5 into the formula;
h = -16t^2 + 80t + 25
h = -16(2.5)^2 + 80(2.5) + 25
h = -16(6.25)+225
h = -100+225
h = 125
Hence the maximum height the arrow reaches is 125feet
