find the value of a, x, y and z​
PLEASE HELP ME !!!!!!

Answer:

  x = -3/2

Step-by-step explanation:

The removable discontinuity is at the value of x where a denominator factor cancels a numerator factor, and those factors are zero.

  [tex]p(x)=\dfrac{2x+3}{4x^2-9}=\dfrac{2x+3}{(2x+3)(2x-3)}=\dfrac{2x+3}{2x+3}\cdot\dfrac{1}{2x-3}\\\\p(x)=\dfrac{1}{2x-3}\qquad x\ne-3/2[/tex]

That cancellation occurs where 2x+3 = 0, at x=-3/2.

The function p(x) has a removable discontinuity when x = -3/2.

Answer:

no

Step-by-step explanation:

Answer:

Step-by-step explanation:

distributive property

-8 + 2x = 12x - 3

add 3 to both sides

-5 + 2x = 12x

subtract 2x from both sides

-5 = 10x

divide by 10 for both sides

-5/10 = x

-0.5 = x

actually it's -1/2 or -0.5

Answer:  The function that models the distance they drive is

f(x) = 50x + 20 where x is the time in hours

reasonable domain:  0 ≤ x ≤ 3

Step-by-step explanation:

examples:

95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.

120 = 50(2) + 20  This means that after 2 more hours they will reach their destination.

There is a little ambiguity in the question. The function could be written as if they are starting out.  f(x) = 50t  

20 = 50(.4)  At 50 mph it took .4 hours to go 20 miles.

120 = 5(2.4)  The whole trip took 2.4 hours.

Answer:

Option C

Step-by-step explanation:

we have

x+2y=2 ------> equation A

-4x+4y=-8 ------> equation B

Multiply equation B by -1 both sides

-1(-4x+4y)=-8*(-1)

4x-4y=8 -----> equation C

Adds equation A and equation C

x+2y=2

4x-4y=8

--------------

5x-2y=10 ----> equation D

An equivalent system of equations is equation A and equation D

so

x+2y=2 ------> equation A

5x-2y=10 ----> equation D

Answer:

[tex] \sqrt{f {}^{2} } = \sqrt{ \frac{9}{49} } [/tex]

[tex]f = \frac{ \sqrt{9} }{ \sqrt{49} } [/tex]

[tex]f = \frac{3}{7} [/tex] or -3/7

Answer:

[tex]f=-\frac{3}{7},\frac{3}{7}[/tex]

Step-by-step explanation:

[tex]f^2=\frac{9}{49}[/tex]

Square root both sides of the equation:

[tex]\sqrt{f^2} =\sqrt{\frac{9}{49} }[/tex]

The square root of [tex]f^2[/tex] is [tex]f[/tex], so let's rewrite the equation:

[tex]f=\sqrt{\frac{9}{49} }[/tex]

Now, we can make this easier on ourselves by noticing that both the numerator and denominator of the fraction are square numbers, so rewrite the equation:

[tex]f=\frac{\sqrt{9} }{\sqrt{49}}[/tex]

Find the square root of 9 (-3 & 3), and the square root of 49 (-7 & 7). Due to the possibility of the positive or negative solution, there will be two:

[tex]f=-\frac{3}{7} ,\frac{3}{7}[/tex]

Answer:

The answer of this inequality is: x < 12

Step-by-step explanation:

1) First, place out what is given:

[tex]4 - 7x>-5(4+x)[/tex]

2) Distribute -5 to (4 + x)

[tex]4 - 7x > -20-5x[/tex]

3) We want to get x by itself, so we need to move each term to their own side(s):

4 - 7x > - 20 - 5x

+20 + 7x > +20 +7x

---------------------------

24 > 2x

5) Divide both sides by 2

[tex]\frac{24}{2} > \frac{2x}{2}[/tex]

6) Now that you have x alone, your answer is:

[tex]x < 12[/tex]

(I changed the position of x which is why the sign turned around)

Answer:

12 movies

Step-by-step explanation:

Let the number of movies they see be represented by x

Jaycie has a VIP membership to a movie theater, so she pays 27 dollars a year and 6.00 for each movie she sees.

$27 + $6 × x

= 27 + 6x

Claire doesn't have a membership, so she pays 8.25 for each movie she sees.

= $8.25 × x

= 8.25x

How many movies would they have to see in a year in order to pay the same amount?

Jaycie = Claire

27 + 6x = 8.25x

27 = 8.25x - 6x

27 = 2.25x

x = 27/2.25

x = 12 movies

Therefore, they have to see 12 movies in a year in order to pay the same amount.

Answer:

x- intercept = - 16, y- intercept = 8

Step-by-step explanation:

Given

3x - 6y = - 48

To find the x- intercept, let y = 0 in the equation and solve for x

3x - 6(0) = - 48 , that is

3x - 0 = - 48 ( divide both sides by 3 )

x = - 16 ← x- intercept or (- 16, 0 )

To find the y- intercept, let x = 0 in the equation and solve for y

3(0) - 6y = - 48 , that is

0 - 6y = - 48 ( divide both sides by - 6 )

y = 8 ← y- intercept or (0, 8 )

The answer option containing the above number is:

Answer:D 45

Step-by-step explanation:I haven't done this in a long time but from my knowledge it is 45 because the triangle has to add up to 180 and you do 45+45 which will get you 90 leaving you with 2x and x would 45 as well and you would do 2 x 45= 90 and that is how you solve 2x.

But the answer to the question is 45 or D

Answer: Choice B

(x-1)(x^3+x^2+5x+6)

==========================================

Explanation:

The 1 in the upper left box means that x = 1 is a root of the original polynomial.

So this means x-1 is a factor of the original polynomial.

This is because x = 1 leads to x-1 = 0 after subtracting 1 from both sides.

-----------------

The 0 in the last position of the bottom row shows we got a remainder of 0.

Getting a remainder 0 tells us that (x-1) is a factor of the polynomial. This synthetic division table confirms our initial guess.

The other values in that bottom row (1, 1, 5, 6) form coefficients to the polynomial 1x^3+1x^2+5x+6, or simply x^3+x^2+5x+6

-------------------

So we know that (x-1) and (x^3+x^2+5x+6) are factors

Meaning that,

x^4+4x^2+x-6 = (x-1)(x^3+x^2+5x+6)

You can confirm this by expanding out the right hand side (distribution rule).

Answer:

[tex]\displaystyle y=-\frac{1}{5}x+\frac{17}{5}[/tex]

Step-by-step explanation:

Equation of a line

A line can be represented by an equation of the form

[tex]y=mx+b[/tex]

Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.

We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.

Two lines with slopes m1 and m2 are perpendicular if:

[tex]m_1.m_2=-1[/tex]

The given line has a slope m1=5, thus the slope of our required line is:

[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{5}[/tex]

The equation of the line now can be expressed as:

[tex]\displaystyle y=-\frac{1}{5}x+b[/tex]

We need to find the value of b, which can be done by using the point (7,2):

[tex]\displaystyle 2=-\frac{1}{5}*7+b[/tex]

Operating:

[tex]\displaystyle 2=-\frac{7}{5}+b[/tex]

Multiplying by 5:

[tex]10=-7+5b[/tex]

Operating:

[tex]10+7=5b[/tex]

Solving for b:

[tex]\displaystyle b=\frac{17}{5}[/tex]

The equation of the line is:

[tex]\boxed{\displaystyle y=-\frac{1}{5}x+\frac{17}{5}}[/tex]

Its an obtuse triangle because one of the angle n is 98 degrees

Answer:

Obtuse Triangle

Step-by-step explanation:

First we have to find the measure of all the angles. We know that the sum of all angles in a triangles is 180 degrees.

So we add 35 and 47 which is 82 degrees.

Then we subtract 82 from 180 which is 98 degrees. Now we know that angle N is 82 degrees.

We can go ahead eliminate answer choices acute equiangular triangle (that only applies if all angles are 60 degrees) and right triangle (must have a right angle which is 90 degrees).

That now leaves us with acute and obtuse triangle. An acute triangle has angles that are less that 90 degrees. So that only leaves us with the answer choice obtuse triangle, because it has an angle of 98 degrees which is an obtuse angle.

So your answer is Obtuse Triangle.
