Answer:

Step-by-step explanation:

As you see in the equation, there is a simple rule to apply in any equation make you confuse with - or + symbol. When 2 minus symbol ( - ) stand together, it would become positive or plus symbol (+), so in this situation:

5 - [ - ( - 2)]

= 5 - (+ 2)

= 5 - 2

= 3

Which graph models the solution set of 50x + 150y>1500?

hodyreva [135]

Answer:

see attached diagram

Step-by-step explanation:

First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.

When x=0, then 150y=1500, y=10.

When y=0, then 50x=1500, x=30.

Connect points (0,10) and (30,0) to get needed dashed line.

Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because

$50\cdot 0+150\cdot 0=0$
