Mathematics

Art [367]3 years ago

Answer:

Simplifying

(-4x + -2) + -1(13x + 1) = 0

Reorder the terms:

(-2 + -4x) + -1(13x + 1) = 0

Remove parenthesis around (-2 + -4x)

-2 + -4x + -1(13x + 1) = 0

Reorder the terms:

-2 + -4x + -1(1 + 13x) = 0

-2 + -4x + (1 * -1 + 13x * -1) = 0

-2 + -4x + (-1 + -13x) = 0

Reorder the terms:

-2 + -1 + -4x + -13x = 0

Combine like terms: -2 + -1 = -3

-3 + -4x + -13x = 0

Combine like terms: -4x + -13x = -17x

-3 + -17x = 0

Solving

-3 + -17x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + -17x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + -17x = 0 + 3

-17x = 0 + 3

Combine like terms: 0 + 3 = 3

-17x = 3

Divide each side by '-17'.

x = -0.1764705882

Simplifying

x = -0.1764705882

Answer:

x = -3/17

Step-by-step explanation:

<u>Step 1:  Distribute the minus sign</u>

(-4x - 2) - (13x + 1)

-4x - 2 - 13x - 1

<u>Step 2:  Combine like terms</u>

-4x - 2 - 13x - 1

-17x - 3

<u>Step 3:  Solve for x</u>

-17x - 3 = 0

-17x - 3 + 3 = 0 + 3

-17x / -17 = 3 / -17

x = -3/17

Answer:  x = -3/17

Apply division algorithm to find the quotient and remainder on dividing the polynomial 3 x^ + 4 x^ square + 6 x + 9 by x^ + 3x +
Ulleksa [173]

I suppose you mean

\dfrac{3x^3+4x^2+6x+9}{x^2+3x+7}

3x^3=3x\cdot x^2, and if we multiply x^2+3x+7 by 3x we get 3x^3+9x^2+21x. Subtracting this from the numerator gives a remainder of -5x^2-15x+9.

-5x^2=-5\cdot x^2, and multiplying x^2+3x+7 by -5 gives -5x^2-15x-35. Subtracting this from the previous remainder gives a new remainder of 44.

44 has no remaining factors of x^2 in it, so we're done, and

\dfrac{3x^3+4x^2+6x+9}{x^2+3x+7}=\underbrace{3x-5}_{\rm quotient}+\dfrac{\overbrace{44}^{\rm remainder}}{x^2+3x+7}

Help me find the missing angles
Keith_Richards [23]

Answer:

  b) 105°

  d) 130°

Step-by-step explanation:

An external angle has the same measure as the sum of the remote internal angles.

b) ? = 25° +80° = 105°

d) ? = 35° +95° = 130°

_____

This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.

If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...

  A + B + C = 180° = ? + C

If we subtract C, then we find ...

  A + B = ? . . . . . . the fact we used above

Please help with the problem in the picture ^ I’ll give brainliest if you give me a small explanation! :)
kolbaska11 [484]

Answer:

When y=276, x= 23

Step-by-step explanation:

Since they're directly proportional, when divided they have to equal the same.

180/15= 12 and 276/23= 12
