CaHeK987 [17]

Answer:

The coefficient of x is 8

Step-by-step explanation:

Given

P = 2(x+8) + 2(3x) --- Perimeter

Required

Determine the coefficient of x

P = 2(x+8) + 2(3x)

Open bracket

P = 2x + 16 + 6x

Collect like terms

P = 2x + 6x+ 16

P = 8x+ 16

How would you graph the solution set of the system of inequalities {3y≤2x+6} { 2x+y&gt;0}
7nadin3 [17]
1) Solve the first inequality

3y ≤ 2x + 6

=> y ≤ 2x/3 + 2

2) Draw the line y = 2x/3 + 2

3) Shade the region below the line y = 2x/3 + 2

4) Solve the inequality 2x + y > 0

=> y > - 2x

5) draw the line y = -2x

6) Shade the region above the line y = -2x

7) The solution is the region between the two lines shaded including the portion of the line y = 2x/3 + 2
