Answer:
Option B,C and E are solution to given inequality
Step-by-step explanation:
We need to check which ordered pairs from given options satisfy the inequality
Ordered pairs are solutions to inequality if they satisfy the inequality
Checking each options by pitting values of x and y in given inequality
A ) (1, -5)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
B) (-3, - 2)
So, this ordered pair is solution of inequality as it satisfies the inequality.
C) (0, -9)
So, this ordered pair is solution of inequality as it satisfies the inequality.
D) (2, -1)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
E) (5, 4)
So, this ordered pair is solution of inequality as it satisfies the inequality.
So, Option B,C and E are solution to given inequality
Answer:
See explanation
Step-by-step explanation:
From the graph,
- After 1 hour passed, 2 inches of show fell
- After 5 hours passed, 10 inches of snow fell
- And so on
This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is
where k is the slope
Find k:
so the equation is and the slope is k = 2.
The slope means how many inches of snow fell in 1 hour.
In 1 hour, 2 inches of snow fell.
