{4x+2y=18
{2x+3y=15           -divide both sides by -2
                                 -2x-y=-9
                                  2x+3y=15
                            -sum the equations vertically to
                              eliminate at least one variable
                               2y=6 divide both sides of the equation
                                         by 2
                               y=3
             -substitute the given value of y into the simplest equation
                               2x+3*3=15
                                    -solve for x
                                         x=3
                  -the solution of the system is the ordered pair (x,y)
                                   (x,y)= (3,3)
                                         Check √
-check if the given ordered pair is a solution of the system of equations
{4*3+2*3=18
{2*3+3*3=15
simplify the inequalities 
{18=18
{15=15
-since all of the equalities are true the ordered pair is the solution of the system

Answer:

Graph C.

Step-by-step explanation:

If you calculate f for x=0, you get f(0)=3*1=3. This rules out answer A already.

Next, you can expect the graph to approach y=0 for large x. The larger the x, the more times you're multiplying by 0.5. Graph C is the only one that does that. So even without actually graphing it, you know that C is the one.

The perimeter of a rectangle is 52. The length is 2 more than 2 times the width. Find the width and length.
Arlecino [84]
Formula for the perimeter of a rectangle = 2(L + W).
let the width be x
length = 2 + 2x
substitute respectively
52 = 2(2 + 2x + x)
52 = 2 (2 + 3x)
52 = 4 + 6x
52 - 4 = 6x
48 = 6x
divide both sides by 6
48/6 = 6x/6
8 = x
width = 8
length = 2 + 2x = 2 + 2(8) = 2 + 16 = 18
