Answer:
slope: -1/2
y-intercept: -2
Step-by-step explanation:
f(x) = mx+b
m is slope
b is the y-intercept
so
if f(x) = -1/2x - 2
then
the slope or m is -1/2
and the y-intercept or b is -2
Answer:
A 190-pound person would burn 285 calories at the same rate.
Step-by-step explanation:
<em>Calories burn depends on the weight</em>
<em>Weight of first person = 160</em>
Calories burn for 160 pounds in 30 mins = 237
Calories burn rate for 1 pound in 30 mins =
= 1.5
<em>Calories burn for 190 Pound person would be:</em>
Weight of second person = 190
Calories burn for 190 pounds in 30 min:
As the burn rate of calories is same for the two persons:
= rate × weight
= 1.5 * 190
= 285 calories
Answer:
-1 or 1/-1
Step-by-step explanation:
So, the initial number of bacteria in the culture = x
After 1 hour,
The number of bacteria = 185x/100
= 1.85x
After 2 hours,
The number of bacteria = (185 * 1.85x)/100
= 3.42x
So:
3.42x = 12500
x = 12500/3.42
= 3654.97
= 3655
From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.
