Simple geometrical shapes appear on some national flags too. For example, the flag of the Republic of Trinidad and Tobago is made up of two triangles and three parallelograms. The width of each white portion is 1/30 of the length of the flag and the width of the black portion is 2/15 of the length of the flag. Calculate the following ratio : area of red portion : area of black portion : area of white portion.

y = x + 95

y = 42 + 95

y=137 mm hg

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

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.
