This is a problem of inequalities. An inequality stands for the relationship between two values when they are different. In this problem, we need to solve for x. So, we have that:

Subtracting 3b from each side of the equation, we have:

Multiplying by
the direction of the inequality changes if
is greater than zero, so we have that solving for x the result is:

We told to combine like terms of the expression 3x² + 2x + 3x - 1. Immediately, we notice that 2x and 3x have the same variable, x. Therefore, they can be added. Hence, your answer will be 3x² + 5x - 1. Hope this helped and have a phenomenal day!
Subtract the difference in age from the total:
87 - 15 = 72
Divide by 2:
72 / 2 = 36
Sydney is 36 years old
Devaughn is 15 years older: 36 +15 = 51 years old
51 + 36 = 87

Under the assumption that each line on the graph represents 1 unit on both axes.
Step-1: Determine the coordinates of 2 points on the graph
A(-2,1) and B(5,-6)
Step2: Find the slope of the line.
By formula,


Step 3: Find the equation of the line using the formula below:

Hence, the correct answer for equation of the line is y = -x -1
