Answer:

D. Angles BAC and DCA are congruent by the Alternate interior angles theorem.

Step-by-step explanation:

Given ABCD is a parallelogram.

AB=CD and BC=AD

AB\parallel CD \; and\; BC\parallel AD

To prove that AB\cong CD\; and\; BC\cong AD.

Proof: According to given information

AB\parallel CD and segment BC\parallel AD.

Construct diagonal AC with a straightedge.

In \triangle ABC\; and\; \triangle ADC

AC=AC

Reflexive property of equality.

m\angle BCA\cong m\angle DAC

By alternate interior angles theorem.

m\angle BAC\cong m\angle DCA

By alternate interior angles theorem.

\triangle BCA\cong\triangle DAC

By ASA( Angle-Side_Angle) theorem.

By CPCTC opposite sides AB and CD, as well as BC and DA are congruent.

Hence proved.

What is the horizontal asymptote of the function f(x)= -2x/x+1
daser333 [38]

<u>Answer:</u>

-2

<u>Step-by-step explanation:</u>

We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.

Recalling the rules for a horizontal asymptote:

1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.

2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.

3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.

Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.

Horizontal asymptote = -\frac{2}{1} = -2
