the sum of two rational numbers is -8. if one of the is -8/17, find the other​

Answers

Answer 1

Let other one be x

ATQ

[tex]\\ \sf\longmapsto x+\dfrac{-8}{17}=-8[/tex]

[tex]\\ \sf\longmapsto\dfrac{17x-8}{17}=-8[/tex]

[tex]\\ \sf\longmapsto 17x-8=17(-8)=-136[/tex]

[tex]\\ \sf\longmapsto 17x=-136+8[/tex]

[tex]\\ \sf\longmapsto 17x=-128[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{-128}{17}[/tex]

Answer 2

Answer:

[tex]let \: the \: unknown \: = x \: and \: y \\ x + y = - 8 \\ y = \frac{ - 8}{17} \\ x - \frac{8}{17} = - 8 \\ x = - 8 + \frac{8}{17} \\ x = \frac{17 \times - 8 + 8}{17} \\ x = \frac{ - 136 + 8}{17} \\ x = \frac{ - 128}{17} \\ thank \: you[/tex]

What is an equation of the line that passes through the point (2,-6) and is parallel
to the line 3 -
2y = 8?

Answers

9514 1404 393

Answer:

  x -2y = 14

Step-by-step explanation:

The x- and y-coefficients can be the same. The constant needs to change to make the given point satisfy the equation.

  x -2y = (2) -2(-6) . . . . . use (x, y) = (2, -6) to find the constant

  x -2y = 14

Answer:

[tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

By subtracting x³ - 3x² + x - 1 , that is

[tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - (x³ - 3x² + x - 1) ← distribute by - 1

= [tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - x³ + 3x² - x + 1 ← collect like terms

= [tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

x⁴ + 5x³ - 6x² - 5x - 2

should become

x³ - 3x² + x -1

so, what do I need to subtract from the top terms to get the bottom terms ?

because we can only look from one x- term to the next. we can only combine them, when they have the same x exponent.

so, we see there is no x⁴ in the desired result.

therefore, we know as a first item that x⁴ had to be subtracted.

the next x exponent is 3.

we have 5x³ on the top, and x³ on the bottom.

so, clearly, we need to subtract 4x³ as second term.

the next x exponent is 2.

we have -6x² on the top, and -3x² on the bottom.

so, we should actually add 3x². and how do we do this in a subtraction ? by subtracting a negative value, which actual adds it.

so, we need to subtract -3x² as third term.

the next x exponent is 1 (just x).

we have -5x on the top and x on the bottom.

so, the same trick as before, as we need to add something.

so, we need to subtract -6x as fourth term.

and finally, the x exponent 0, which just shows the constant numbers.

we have -2 on the top and -1 on the bottom.

again the same trick to actually add 1.

we need to subtract -1 as fifth term.

so, in total, this is what we need to subtract from the top line to get the bottom line :

x⁴ + 4x³ - 3x² - 6x - 1

What are the coordinates of the midpoint at (-3,9) and (10,18)

Answers

Answer:

(7/2, 27/2) or (3.5, 13.5)

Step-by-step explanation:

The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.

The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

x-coordinate of the midpoint:

(-3 + 10)/2 = 7/2

y-coordinate of the midpoint:

(9 + 8)/2 = 27/2

Answer: (7/2, 27/2) or (3.5, 13.5)

Answers

Answer:

x = 3

Step-by-step explanation:

Given

2(x - 4) = 7 - 3x ← distribute parenthesis on left side

2x - 8 = 7 - 3x ( add 3x to both sides )

5x - 8 = 7 ( add 8 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3
