For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)
<span>= ( 0, 12) </span>
<span>AC = 12 </span>
<span>B - C = (7 - 3) - ( - 2 -3) </span>
<span>= (9, 0) </span>
<span>BC = 9 </span>
<span>ABC is a right -angled triangle with AC as the hypotenuse </span>
<span>AC = sqrt( 9^2 + 12^2) </span>
<span>= sqrt(81 + 144) </span>
<span>= srqt(225) </span>
<span>= 15 </span>
<span>Perimeter = 12 + 9 + 15 </span>
<span>= 36 units </span>
<span> So the answer is 36 units
</span>I hope my answer helped you.
Answer: (-2, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the <em>x</em> and <em>y</em> that is the solution to this system of equations.
The two lines intersect in quadrant III
where <em>x</em> and <em>y</em> are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 2 and down 1 so that's (-2, -1).
So the solution to this system is (-2, -1).

Answer:
weight of legs - 7 ounces
weight of wings - 4 ounces
Step-by-step explanation:
Let the weight of a chicken leg be represented by l
Let the weight of a chicken wing be represented by w
The total weight of Mr. Nguyen's package can be represented by this equation :
4l + 6w = 52
The total weight of Ms. Dawen's package can be represented by this equation :
3l + 6w = 45
To find the weight of the legs and wing, use simultaneous equation
4l + 6w = 52 eqn 1
3l + 6w = 45 eqn 2
Subtract equation 2 from 1
l = 7 ounces
Substitute for l in equation 1
4(7) + 6w = 52
28 + 6w = 52
Solve for w
w = 4 ounces
