Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows

the solution to the system of equations and explains why? (−3, −5), because the point satisfies one of the equations (−3, −5), because the point lies between the two axes (−4, −8), because the point satisfies both equations (−4, −8), because the point does not lie on any axis

(-4,-8) because it satisfies both equations

Answer:

The solution is (-4,-8)because the point satisfies both equations.

Step-by-step explanation:

Line A: y = x − 4

Line B: y = 3x + 4

Substitute the value of y from Line A in Line B

x-4=3x+4

-4-4=2x

-8=2x

-4=x

Substitute the value of x in Line B to get value of y

y=3x+4

y=3(-4)+4

y=-12+4

y=-8

Thus the solution is (-4,-8)because the point satisfies both equations.

Consider the following equation f(x)=(x^2+4)/(4x^2-4x-8)
kifflom [539]

<em><u>Question:</u></em>

Consider the following equation: f(x)=x^2+4\4x^2-4x-8 name the vertical asymptote(s)

<em><u>Answer:</u></em>

The vertical asymptotes are x = 2 or x = -1

<em><u>Solution:</u></em>

Given that,

f(x)=\frac{x^2+4}{4x^2-4x-8}

For vertical asymptotes, set the denominator to zero and then solve the quadratic equation

4x^2-4x-8=0\\\\Divide\ by\ 2\\\\x^2 - 2x - 4 = 0

Split\ the\ middle\ term\\\\x^2+x-2x-2=0\\\\Group\ the\ equation\\\\(x^2 + x) - (2x + 2) = 0\\\\Factor\ the\ common\ term\\\\x(x + 1) - 2(x + 1) = 0\\\\(x + 1)(x - 2) = 0\\\\Therefore,\\\\x + 1 = 0\\\\x = -1\\\\And\\\\x - 2 = 0\\\\x = 2

Thus the vertical asymptotes are x = - 1 and x = 2

33. Construct a truth table to show that the following argument is valid.
GuDViN [60]

Answer:

  see attached

Step-by-step explanation:

Perhaps you want to show that P∨Q will be equal to Q when ¬P is true. Attached is a truth table that shows this is the case.

__

This is simply a restatement of the logic of the OR function. When one its inputs is a logical 0 (false), the output depends on the other input(s).

Answer:

x > 136

Amount spent on roses = $184

To male a profit of at least $360

The total revenue made from rose sale must be :

Cost price + profit made

$184 + $360 = $544

To make a profit of at least, $360, them he must sell at least :

$544 / selling price

$544 / $4

= 136

x > 136
