On saturday afternoon, armand sent mmm text messages each hour for 555 hours, and tyrone sent ppp text messages each hour for 444 hours. which of the following represents the total number of messages sent by armand and tyrone on saturday afternoon?

555m +444p =999

Step-by-step explanation:

Let suppose

Armand sent messages in 555 hours= m

Tyrone sent messages in 444  hours  = p

then

total number of messages sent by Armand and Tyrone on Saturday afternoon is       m + p =  555 +444 =999

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
