Answer:
1.5
Step-by-step explanation:
We can set up the equation 0.50X = 0.750
Divide by 0.5 and we get .75/.5=1.5
This is an exponential decay function of the form:
y=ab^x, In this case:
y=15000(0.8^t) so for t=3
y=15000(0.8^3)
y=$7680
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:
x = 1 or x = -3
Step-by-step explanation:
+ bx + c = 0
x = 
as 
+ 2x - 1 = 2 ⇔ + 2x - 3 = 0, its solution is
x = 
= 
= 
= 
therefore, x = 1 or x = -3
hope this helps! :D
have a miraculous day, and brainliest is immensely appreciated!! <3
