Answer:
7.5 feet
Step-by-step explanation:
large over small=64/27
r:4/3
4/3=10/h
4h=30
h=30/4
h=7.5 feet
Both factors are negative so the result would be positive. C. Is the answer
C. y=-2x+1
You can test this by inputting each value of X into that equation, noticing that the Y value is always correct when you use that equation.
X = -(-1) +/- sqrt((-1)^2 - 4*4*3)
------------------------------------ = 1/8 +/- sqrt47i
2 * 4
None of the choices are correct
