Because there is a +e and a -e in the two equations we can simply add them together to solve for d...
2d+e+d-e=8+4 combine like terms
3d=12 divide by 3
d=4, now use this d in either original equation to solve for e...<span>d–e=4 so
4-e=4 subtract 4
-e=0
e=0
So the solution, where the lines intersect graphically, is the point (4, 0)</span>
Answer:
Step-by-step explanation:
All you need to do is isolate the x.
First, add 64 to both sides:
Then, take the square root of both sides:
Actually, that is:
Here's the reason for that. An example would be:
Here, you'd take the square root of both sides to solve for x.
Right? But X could also be a -2, because a negative times a negative is a positive.
Therefore, or
If the unknown side is a leg, the hypotenuse must be 26 (the longest of the other two sides). Then the Pythagorean theorem tells you
... 26² = 24² + y²
... y = √(26² -24²) = √100 = 10
The appropriate choice is
... 10
