Y=(5x-4)/2 first move -2y to the other side to obtain a positive value and make y the subject
Answer: x = 2
Step-by-step explanation:
First you add -4x and -6x to get -10x. Then you will have -20 = -10x. So you divide both sides by -10 to get 2 = x
Given the equation :

We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :

The average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.
<h3>What is the average rate of change?</h3>
The average Rate of Change of the function f(x) can be calculated as;

Interval -3 ≤ x ≤-1
a = -3, b = -1
f(a) = f(-3) = -20
f(b) = f(-1) = 0
Step 2: Find Average

Therefore, the average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.
