Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:
Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:
Putting the values
Putting the value of slope
Putting a pair of input-output in the equation (1,75)
Putting the value of b
Hence,
The rule is: y = -10x+85
6,000 m

Answer: it will be 4,000 km
Step-by-step explanation:
Answer: The required ratio in simplest form is 1 : 40.
Step-by-step explanation: We are given to express the ratio 45 seconds to 30 minutes as a fraction in simplest form.
We know that
1 minute = 60 seconds.
So, 30 minutes = (30 × 60) = 1800 seconds.
Therefore, the ratio is given by
Thus, the required ratio in simplest form is 1 : 40.
