What is the apparent solution to the system of equations?
1 answer:
Answer:
(x, y) = (-0.3, -1.6)
Step-by-step explanation:
The graph below shows these equations graphed. Their point of intersection is (-0.3, -1.6).
_____
<em>Analytical solution</em>
You can equate the expressions for y to get ...
... 12x +2 = 2x -1
... 10x = -3 . . . . subtract (2x+2)
... x = -0.3 . . . . . divide by 10
... y = 2(-.3)-1 = -1.6 . . . . use the 2nd equation to find y.

Answer:
a.
b.
Step-by-step explanation:
a. The sides of an Equilateral triangle are all equal.
Then, in this case:
Based on this, you can identify that AD divides the side BC into two equal parts and the triangle into two equal Right triangles. Then:
Knowing the length CD, you can find "x" using the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs.
In this case:
Substituting values and solving for "x", you get:
b. By definition, the measure of each interior angle of an Equilateral triangle is 60 degrees. Therefore:
