Answered: (3x-1)^2 (x+6)^2

Mon, 20 Jan 2025 02:46:40 +0000

I assume you are trying to expand this into a 4th order polynomial...
First, multilply (3x-1) by (3x-1) to get (9x^2-6x+1)
Then, multiply (x+6) by (x+6) to get (x^2+12x+36).

Now, multiply (9x^2-6x+1) by (x^2+12x+36) to get the answer.

Answered: -5x + 4y = 3, x = 2y - 15

Sat, 21 Dec 2024 07:22:43 +0000

I'm not certain what you are asking here, but you've posted two linear equations in x and y. They are not the SAME equation, so they have a single shared solution in X and Y.

The easiest approach to finding this solution (with or without a calculator) is to solve each of them for "Y". Then you can either set them equal to each other and solve for X, or you can graph them both and see where they cross.

solvle 1st equation for y: 5x - 4y = -3
5x - 5x - 4y = -3 - 5x ; subtract 5x from both sides
-4y = -5x - 3 ;
-4y/-4 = (-5x - 3) / 4 ; divide both sides by -4
y = (5/4)x + 3/4

Solve 2nd equation for y: x - 2y = -15
x - x - 2y = -15 - x ; subtract -x from both sides
-2y = -x - 15
(-2y)/-2 = (-x - 15)/-2 ; divide both sides by -2
y = x/2 + 15/2

Since you solved them both for y, you can set the two "x" expressions equal to each other and solve for x.
(5/4)x + 3/4 = x/2 + 15/2 ; multiply everything by 4
5x + 3 = 2x + 30 ; subtract 2x from both sides
3x + 3 = 30 ; subtract 3 from both sides
3x = 27 ; divide both sides by 3
x = 9
Now substitute the 9 for x in either original equation and solve for y.
y = 9/2 + 15/2
y = 24/2
y = 12

So, the final answer is (9, 12).

Answered: why isn't 1+2sin(7pi/6) = 0

Wed, 13 Mar 2024 06:00:39 +0000

I don't own a TI inspire CX II, but I'm going to guess the difference lies in "rounding error". On my TI-84 Plus, when I enter "sin(7PI/6)" it returns "-.5". If it returns anything else, you probably are seeing a "rounding error" somewhere in the sin() function. For all practical purposes, any computer that gives a floating point answer with an exponent of less than -7 can be considered to be zero.

Answered: solve for the hole 5(x-2)(x+2)/-4(x-5)(x+2)

Wed, 13 Mar 2024 05:44:31 +0000

You've presented a rational expression of "(5(x-2)(x+2)) / (4(x-5)(x+2))". I assume by "hole", you mean places where the domain is not defined. In this case, the expression is not defined if the denominator is equal to zero. This denominator is equal to zero whenever (x-5)=0 or (x+2)=0, or whenever x=5 or x=-2.

Answered: 11x − 20y = 5

Wed, 22 Nov 2023 05:30:55 +0000

That's a very nice linear equation in "Standard Form". It's arranged so that the x variable is first with a positive coefficient, the y variable is second and the constant term is on the right side of the equation by itself.

I'm not certain what you want to do with it, but we can put it in "slope-intercept" form where we simply solve it for "y".

In this case start by adding "-11x" to both sides to get:
11x - 20y -11x = 5 - 11x
next, combine the like x terms on the left side:

11x - 11x -20 y = 5 - 11x
-20y = 5 - 11x
divide both sides by -20 to get:
y = 5/-20 -11x/-20
y = (11/20)x - 1/4
This shows that it is a linear equation with a slope of 11/20 and a y intercept of 1/4.
Since it's in slope/intercept form you can enter it in the graph editor using the [y=] key as:
y1 = 11x/20 -1/4
and then press the [GRAPH] key to graph the equation.

Answered: how do i find y=1x-5y

Sun, 19 Nov 2023 05:37:14 +0000

Your question makes no sense unless you've accidentally typed and extra "y" in your equation.
If what you really meant for your equation was "y = 1x - 5", then this is an equation in slope-intercept form with a slope of 1 and a y-intercept of 5. To find the x-intercept, solve the equation for x to get "x = y + 5". This gives you an x-intercept of 5.

Answered: Line ℓ1 has the equation y= – x+5 and line ℓ2 has the equation x+y= – 1. Find the distance between ℓ1 and ℓ2.

Sat, 18 Nov 2023 00:47:26 +0000

That's an interesting question. If you re-write both equations in standard form, you find:

y1(x) = -x + 5

y2(x) = -x - 1

Both equations have the same slope (-1), but different y-intercepts (5 and -1). So the vertical distance (along the y-axis) is simply 5 - (-1) = 6.

But if we're talking about about the shortest distance between them, then we need to find a line perpendicular to them both and see how far apart the intersection points are using the distance formula (Pythagorean Theorem). The perpendicular line will have a slope that is the negative reciprocal of -1 which is a new slope of -(1/-1) = 1. Just for fun we'll pick a y-intercept of 5 to match y1(x) and get a new line of:

y3(x) = x + 5

This y3(x) intersects y1(x) at (0,5). To find the intersect of y3(x) with y2(x), we set them equal to each other and solve for x.
-x - 1 = x + 5
-6 = 2x
x = -3
Subsititute for x=-3 in EITHER y3 or y2 and we get y=2, so a pair of points to look between are (0,5) and (-3,2). Find the distance between these two points, and you'll have the distance between the lines.

Sqrt((0-(-3))^2 + (5 - 2)^2) = Sqrt(3^2 + 3^2) = 3*Sqrt(2) = 4.2426...

So, the final answer(s) are, Vertical distance between the parallel lines = 6, and perpendicular distance between the parallel lines = 3*Sqrt(2) or approximately 4.2426...

Thu, 11 Jan 2018 19:21:00 +0000

I'm a TI-8x neophyte and I may never need to know anything more about the machine than this.

Is there is a way to convert a complex number in polar form having an angle in degrees, to rectangular form, that is is easy to do as the inverse operation is?

So far the simplest (!) approach I've found is to enter the complex number in exponential form with an inline conversion from degrees to radian measure in the imaginary exponent. Even speaking that sentence to the student I'm trying to assist is going to blow his head off.

You can't. You will have to graph functions written in terms of y (instead of x) as the same function in terms of x and understand that the graph would be rotated 90 degrees. For example, y^2 = x would be graphed as y = x^2 and then rotated 90 degrees clockwise in your mind.
