There is no simplest fraction, because no same numbers go into 33 and 100. (The hundred is from 33/100, because 33% and 33/100 are the same thing.
A)
well, we know the elevator's rate is -20 f/s, ok, so every second, is dropping 20 feet, therefore, "y" is "distance from the ground floor", so when y = 0, meaning the distance to the ground floor is 0, so you ARE at the ground floor then.
and "x" is how many seconds you've been in the elevator.
now, she got in the elevator for 6 seconds, so, the elevator went down by 20 * 6, or 120 feet down, reason why the slope is negative, when she stopped, she was 350 feet away from the ground floor still though.
if the elevator went down 120 feet, and she's still 350 feet from the ground floor, that means she boarded the elevator at 120 + 350 feet, or 470 feet.
b)
Answer:
60$ is the normal price.
Why:
Because if 45$ is 75%, then 30$ is 50%, 15 is 25%, and 0 is 0%. 50% + 50% = 100%. (That's how I did this one, anyway. This works on any 25%, 50%, or 75% problem.)
Answer:
2x+4
Step-by-step explanation:
The equation of the line in point-slope form is expressed as;
y - y0 = m(x-x0)
Using the coordinates (0,4) and (-2, 0)
Slope = 0-4/-2-0
slope = -4/-2
slope = 2
Substitute m = 2 and the point (0,4) into the formula;
y - 4 = 2(x-0)
y - 4 = 2x
since y = 4 + 2x
y = 2(x+2)
Hence the required equation is 2x+4
