Answer:

x=3

Step-by-step explanation:

-2x-6=3x-21

Add 21 to both sides of the equation

  • -2x-6+21=3x-21+21
  • -2x+15=3x

Add 2x to both sides of the equation

  • -2x+2x+15=3x+2x
  • 15=5x

Divide each side by 5 to isolate x

  • 15÷5=5x÷5
  • 3=x

Which of the following represents the polynomial 5x + 3x^4 + 15 − 7x3 in standard form, the degree of the polynomial, and the nu
kkurt [141]
A polynomial is written correctly when the exponents are listed in order from highest to lowest.  The highest exponent then dictates the degree of the whole polynomial.  The first choice above is written in standard form from highest degree to lowest.   Doesn't matter that we might skip the x-squared term or any other x-term, as long as they're in order from highest to lowest.  The degree on that first polynomial, the one you're after, is 4 because that's the highest exponent, and there are 4 terms there.  Terms are "bunches" of numbers and variables stuck together by multiplication and separated by + or - signs.

What is the equation of the line that is parallel to line y = -3x – 8 and passes
qwelly [4]

Answer:

y = -3x + 3

Step-by-step explanation:

Since the line is parallel, it has the same slope. Plug the point you have into the equation y - y1 = slope (x -x1) to get your answer, which should be y = -3x +3

Hopefully this helps - let me know if you have any questions!

<h3>Answer:   1260</h3>

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

Work Shown:

n = number of sides = 9

S = sum of the interior angles of any polygon with n sides

S = 180(n-2)

S = 180(9-2)

S = 180(7)

S = 1260
