Answer:
when its a linear equation
Step-by-step explanation:
<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:
y<=-3x-3
Step-by-step explanation:
m=y2-y1/x2-x1
m=-6-3/1-2
m=-3
y-y1=m(x-x1)
y-3=-3(x-(-2))
y-3=-3x-6
y=-3x-6+3
y=-3x-3
we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x-3
Answer:
93/100
Step-by-step explanation:
23/100 + 7/10
