Answer:
(16x² - 72x + 85) / (4x-9)
Step-by-step explanation:
first put g(x) into h(x)
h(g(x)) = 4(x-2) - 1 = 4x - 8 - 1 = 4x - 9, then
f(h(g(x))) = (4x - 9) + (4/4x-9) = ((4x-9)(4x-9) + 4)/(4x-9) =
(16x² - 72x + 81 + 4)/(4x-9) = (16x² - 72x + 85)/(4x-9)
If you are missing parentheses around (x+4)/x, then the answer would be different.
Answer:
7.142m/s
Step-by-step explanation:
Velocity=change is distance/change in time
change in distance=400m-0m=400m
change in time=56-0=56seconds
v=400m/56s
v=7.143m/s
You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.
Answer: c. Multiply the second equation by 2.
It only has symmetry about the axis, that means that if i were to draw a line down the middle, the triangle looks the same on both sides. If it were split in half horizontally, it would not be symmetrical.
