Answer:
The answer is (-5/24, -7.5).
Step-by-step explanation:
There are two methods to solving a system of equations - substitution or elimination. In this example, we can use elimination since the coefficients of 'x' are opposite signs. To complete elmination, we simply add the equations together:
-12x - 5y = 40
<u>+ 12x - 11y = 80</u>
-16y = 120
Use inverse operations to solve for 'y' by dividing both sides by -16 to get y = -7.5.
Next, plug in the value of 'y' into one of the equations and solve for 'x':
-12x - (5)(-7.5) = 40 or -12x + 37.5 = 40, now subtract 37.5 from both sides: -12x + 37.5 - 37.5 = 40 - 37.5 or -12x = 5/2. Lastly, divide both sides by -12 to solve for x, x = -5/24.
Answer:
19 square units
Step-by-step explanation:
There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes. For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.
Rectangle: would be from -3 to 3 (6) and -2 to 4 (6). 6x6=36
The four missing triangles:
AB = 1/2(3)(2)=3
BC = 1/2(2)(4)=4
CD = 1/2(2)(4)=4
DA = 1/2(4)(3)=6
6+4+4+3=17
36-17=19
