Step-by-step explanation:
(35/5) - 5
7 - 5 = 2
Answer:
f(x)=−5x−20
Step-by-step explanation:
It's decreasing 5 degrees every hour, which is represented by -5x
You also have to take away the 20 (-20) from where it started.
So, f(x)=−5x−20
Step-by-step explanation:
answer is B
use unitary method to solve it
Answer: Option B, a linear relation.
Step-by-step explanation:
Let's analyze the points in the data:
the first 3 pairs are: (0,14.70) (10,19.03) and (20, 23.36)
We can see the differences between consecutive points and see if the relation is linear:
(10,19.03) - (0,14.70) = ( 10 - 0, 19.03 - 14.70) = (10, 4.33) now we need to see the quotient: 4.33/10 = 0.433
(20, 23.36) - (10,19.03) = (20 - 10, 23.36 - 19.03) = (10, 4.33), and the quotient is the same as before.
This means that the relation is a linear relation, where the slope os 0.433 and the x-intercept is 14.70, so the equation can be written as:
y(x) = 0.433*x + 14.70
