The question is wrong since population is not counted in points . for question like these use formula :P(1+R/100)^t where p is current population,r is rate and t is time.
Take two points
(-3, -1) and (1,2)
Find slope
slope formula: m = y2 - y1 / x2 - x1
m = 2 - (-1) / 1 - (-3) = 2 + 1 / 1 + 3 = 3/4
Substitute one of the points into slope intercept form (y =mx + b) to find the y intercept.
y= mx + b
2 = 3/4(1) + b
2 = 3/4 + b
1.25 = b
So:
y = 3/4x + 1.25
4x = 10y + 20
10y = 4x - 20
y = 4/10x - 2
Solution: y intercept is -2
Answer:
"Snack B and C are same ratio"
Step-by-step explanation:
We need to reduce each fraction and determine whether the ratios are same or not.
3/150 = 1/50
Checking A:
2/75 = 1/37.5
So, this is not equal to 1/50
Checking B:
4/200 = 1/50
THis is the same, so this is equal to 1/50
Checking C:
1/50
it is directly given, so this is equal as well
Hence, Snack B and C are same ratio.
Answer:
25%
Step-by-step explanation:
50+30 = 80
15 + 5 = 20
20/80 = 0.25, or 25%
