Therefore the answer is A.
![( {x}^{2} - {y}^{2} ) = (x + y)(x - y)](https://tex.z-dn.net/?f=%28%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%7By%7D%5E%7B2%7D%20%29%20%3D%20%28x%20%2B%20y%29%28x%20-%20y%29)
Here is the formula that is used for answering.
Answer:
- y1 = -x +5
- y2 = 2x +14
- (x, y) = (-3, 8)
Step-by-step explanation:
We notice that x=0 is halfway between x = -1 and x = 1, so the corresponding y-intercepts will be ...
for y1, (6+4)/2 = 5
for y2, (12+16)/2 = 14
Each step in x is +2. The steps in y1 are -2, so the slope is -2/2 = -1.
The steps in y2 are +4, so the slope is 4/2 = 2.
Now, we have the slopes and intercepts, so we can write the system of equations as ...
y1 = -x +5
y2 = 2x +14
__
The y-values are shown as equal in the table for x=-3, so the solution of the system of equations is ...
(x, y) = (-3, 8)
Answer:
The number of subsets of a set containing 10 elements is 2^10=1024.
Step-by-step explanation:
Slope = (-1+7)/(-4-2) = 6/-6=-1
answer
-1
Answer:
Step-by-step explanation:
If you know perimeter, an area you can find by formula
s = P/2
A =
If P ≈ 32.3177 units , then A ≈ 47.9 units²
