Answer:
a)after 1,000 years?
1 meter
b) 10 million years?
10,000 meters
c) 50 million years?
50,000 meters
Step-by-step explanation:
We are told in the question that mountains rise 1 mm per year.
a) After 1000 years
1 year = 1 mm
1000 years =
Cross Multiply
1000 × 1 mm
= 1000mm
Converting to meters
1 mm = 0.001 m
1000 mm =
1000 × 0.001m
= 1 meter
b) After 10 million (10,000,000) years
1 year = 1 mm
10000000years =
Cross Multiply
10000000 × 1 mm
= 10,000,000mm
Converting to meters
1 mm = 0.001 m
10,000,000mm =
10,000,000 × 0.001m
= 10,000 meters
c) After 50 million years(50,000,000)
After 50,000,000 years
1 year = 1 mm
50,000,000years =
Cross Multiply
50,000,000 × 1 mm
= 50,000,000mm
Converting to meters
1 mm = 0.001 m
50,000,000mm =
50,000,000 × 0.001m
= 50,000 meters
Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.

Answer:
The answer to your question is 1
Step-by-step explanation:
Data
slope = m = -3
y-intercept = 3
Process
1.- Find the equation of the line in the slope-y-intercept form
y = mx + b
-Substitution
y = -3x + 3
2.- Find the x intercept
-If y = 0
0 = -3x + 3
-3 = -3x
-3/-3 = x
x = 1
-The x-intercept is 1
