You divide -15 on both sides to keep the x alone
-240/ -15=16
A negative divided by a negative is a positive so x=16
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.
Answer:
y=2x+500
y=-3x+450
Step-by-step explanation:
X<2 or x>=2
the answer is D, all real numbers
x can be less than 2 OR x greaterthan/equal to 2
