Answer:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴
∴ - equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴
Now, lets put the value of y from equation 1
⇒
⇒
⇒
∴
Next, substituting the value of x in equation 1
⇒
∴
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.
<h2>Answer:</h2>
The rate of change between the points (–3, 0) and (–2, –5) is:
-5
<h2>Step-by-step explanation:</h2>The rate of change between the points (-5, 10) and (-4, 5) is -5.
Now we are asked to find the average rate of change between (-3,0) and (-2,-5)
We know that the average rate of change between two points (a,b) and (c,d) is calculated by the formula:
Here we have:
(a,b)=(-3,0) and (c,d)=(-2,-5)
Hence, the average rate of change is:
Also, we know that for any linear function the average rate of change is same between any two points.
Hence, the answer is:
-5
