Answer:
just by looking at the graph you can see that the y int is one, so that eliminates two answers already. Then the slope is rise over run. (best thing to remember in math. rise over run) so pick two points. (0, 1) and (4,0) were the first ones i saw. to get from those two points you go from (0,1) over 4 (thats your run) and from there down 1 (thats your rise) to get to (0,4). You would then do rise over run (and because your rise goes down its negative) to get -1/4 as your slope. The answer is slope= -1/4, Y intercept = 1
Answer:
The right answer for the question is 6.
Answer:
a) y=8
b) x= 9
Step-by-step explanation:
a)
y/16= 2/4
y= 16 * 1/2 (cross multiply)
y= 8
b) x/5 = 36/20
x= 5 * 36/20 (cross multiply)
x= 9

Step-by-step explanation:
Answer:
6 days ; 2300 calories
Step-by-step explanation:
Given the following :
Current consumption :
Simba = 1520 calories per day
Increases by 130 calories per day : After d days ;
S(d) = 1520 + 130d
Where ; d = number of days
Cuddle = 3380 calories
Decreases by 180 calories each day; after d days ;
S(d) = 3380 - 180d
Pattern continues until they both consume same number of calories each day
S(d) = C(d)
1520 + 130d = 3380 - 180d
130d + 180d = 3380 - 1520
310d = 1860
d = 6
Number of calories they will be consuming them ;
Using : S(d) = 3380 - 180d
S(6) = 3380 - 180(6)
S = 3380 - 1080
S = 2300
They will be consuming 2300 calories by then.
