(-2,1),(-1,3),(0,5),(1,3),(2,1)
Answer:
Let's simplify step-by-step.
34(5a−16)−13(6a−3)
Distribute:
=(34)(5a)+(34)(−16)+−2a+1
=154a+−12+−2a+1
Combine Like Terms:
=154a+−12+−2a+1
=(154a+−2a)+(−12+1)
=74a+−11
Answer:
=74a−11
<h2>
Explanation:</h2>
Let's use a trial and improvement method to find this solution.
Step 1. Let's choose x = 8.5
Substituting into the equation:

Step 2. Let's choose x = 8.4
Substituting into the equation:

Step 3. Let's choose x = 8.3
Substituting into the equation:

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:
Answer:
2
Step-by-step explanation:
as H=20 and W=10
So H=constant.(W)
H=2(10)
H=20
So constant is 2
