Answer:

(4, 2)

Step-by-step explanation:

First we need to reflect the shape across the y-axis, I just flipped the image, so when flipped, the reflected shape will end in quadrant two, quadrant two has only positive numbers, without the reflection, J will be (-4, 2), now that it's reflected across the y-axis, it's (4, 2).

My math problem is 3n(squared) - 28 = -17n I have to factor this! So i would move the 17 over and make it 3n(squared) +17n - 28

wel

It's easier I think to take it and go "what can I add together than makes 17, yet multiplies to 28"
although, I don't think this is a perfect square, either

(x+7)(3x-4) = 0

heres the factored form, but I couldn't even begin to say how I got it, all I know is that it works

Determine the first four numbers of N if N is<br><img src="https://tex.z-dn.net/?f=N%20%3D%20%20%5Csqrt%7B122436486072...2400%7D

Anestetic [448]

Answer:

1106 . . . or
3499

see below for explanation

Step-by-step explanation:

The first four digits of the root depend on whether the exponent in scientific notation is even or odd.

If it is <em>even</em>, then the mantissa of the root is ...

$N \approx\sqrt{1.2243648607}\approx 1.106\dots$

If it is <em>odd</em>, then the mantissa of the root is ...

$N \approx\sqrt{12.243648607}\approx 3.499\dots$

2x - 5y = 4<br> 3x - 7y = 5

VMariaS [17]

Answer:

(-3,-2)

Step-by-step explanation:

2x-5y=4

3x-7y=5

solve the equation

x=2+5/2y

3x-7y=5

substitute the value of x into an equation

3(2+5/2y)-7y=5

multiply 3 to 2. and. 3 to 5/2y

6+15/2y-7y=5

minus 6 to 5 and. add 15/2y to -7y

-1/2y=1

divide both sides by -1/2

y= -2

substitute the value of -2 into an equation

x=2+5/2•(-2)

multiply 5/2 to -2

x=2+-5

add but since 5 is negative then subtract the numbers

x= -3

combine y= -2 and x= -3 as a point

So the answer is (-3,-2)

Divide x ^ 4 + x - 1 by x - 1

vladimir2022 [97]

The required, divide is given by $=x^3+x^2+x+2+\frac{1}{x-1}$

<h3>What is fraction of polynomial?</h3>

Fraction of polynomial is, in the numerator and in the denominator of a fraction there is polynomial function

$=x^3+\frac{x^3+x-1}{x-1}\\$

$=x^3+x^2+\frac{x^2+x-1}{x-1}\\$

$=x^3+x^2+x+\frac{2x-1}{x-1}\\$

$=x^3+x^2+x+2+\frac{1}{x-1}$

Thus the required, divide is $=x^3+x^2+x+2+\frac{1}{x-1}$ .
