The correct answer is A.
For y=x, the slope is 1, meaning that as x increments by 1, y also increments by 1.
Using this logic, we know that the graph goes up looking from left to right.
If both ends were to point up or down it would resemble more of a quadratic (parabola).
Answer:no
Step-by-step explanation:
the answer in decimal form would be 8.727273
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
The answer is b (I think not really sure)
