Answer:

none

Step-by-step explanation:

if we plot it, it's clear, but you might also spot that the plotted lines will be parallel in the equation

because x and y in line two are the same multiple of these in line one (both values are just the half)

plotted with desmoes

B is the midpoint of AC. What is the length of AB? AB is 9x+7 and BC is -3x+20
ahrayia [7]
<h3>Answer:</h3>

AB = \frac{67}{4}\\

<h3>Step-by-step explanation:</h3>

If B is the midpoint of \overline{AC} then AB is just half of AC and also, BC is just half of AC. This means that AB must be equal to BC. Essentially, 9x +7 = -3x +20 and we can solve for the of x from that equation.

9x +7 = -3x +20 \\ 9x +7 +3x = -3x +20 +3x \\ 12x +7 = 20 \\ 12x +7 -7 = 20 -7 \\ 12x = 13 \\ \frac{12x}{12} = \frac{13}{12} \\ x = \frac{13}{12}

Now we can solve for AB

AB = 9(\frac{13}{12}) +7 \\ AB = 3(\frac{13}{4}) +7 \\ AB = \frac{39}{4} +7 \\ AB = \frac{39}{4} +\frac{28}{4} \\ AB = \frac{67}{4}

The function f(x) has a vertical asymptote at x= [blank].
Alex73 [517]

Answer:

The vertical assymptote is at x = 0

Step-by-step explanation:

Vertical assymptote are simply defined as lines that correspond to the points where the denominator of a rational function is zero.

From the graph, we can see that the curve remains on the y - axis at x = 0

Thus, the vertical assymptote is x = 0
