3 is the chord.
a chord lies inside a circle and does not continue outside of it.
Answer: (-2,5)
Step-by-step explanation: just graph both equations they are already set up in the form and find the point where they intersect
<h3>
Answer: Choice C</h3>
The -2/5 means we go to the left 2/5 of a full unit. So we take 2 small little steps (going over 2 little tickmarks), then we move 4 small steps to the right due to the +4/5 portion. Ultimately, we end up at 2/5 as the answer
So -2/5 + 4/5 = 2/5
This can be thought of as -2+4 = 2, then you just stick 5 in the denominator for each term.
Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)
The answer is C, mWXY + mYXZ = 180 degrees. This is true because if you look at the diagram, angle WXY and angle YXZ are supplementary angles, meaning that they equal 180 degrees.
