C. 5. MULTIPLE REPRESENTATIONS Use inequalities A and B to investigate graphing
compound inequalities on a coordinate plane.
A. 7(y + 6) 21x + 14
B. -3y = 3x - 12
a. Numerical Solve each inequality for y.
b. Graphical Graph both inequalities on one graph. Shade the half-plane that
makes A true in red. Shade the half-plane that makes B true in blue.
c. Verbal What does the overlapping region represent?

it would be 6xy and -16xy.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
