0.01 equals 1% and 0.1 is 10%, so no, they are not the same
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
First you must know that f(x) means the same thing as y so...
y = 9x - 8
To find the inverse switch the places of x and y and solve for y
x = 9y - 8
x + 8 = 9y
^^^That means the answer is A!
Hope this helped!
