To solve 9=n+10/3 would you multiply the nine by the three? How would you solve this?

iren [92.7K]

Answer:

n = $\frac{17}{3}$

Step-by-step explanation:

Given

9 = n + $\frac{10}{3}$

Multiply through by 3 to clear the fraction

27 = 3n + 10 ( subtract 10 from both sides )

17 = 3n ( divide both sides by 3 )

$\frac{17}{3}$ = n

Which description best compares the graphs given by the equations: x-5y=-5 5x-25y=75

yulyashka [42]

Considering the slopes of the given lines, they are parallel lines.

<h3>When are lines parallel, perpendicular or neither?</h3>

The slope, given by change in y divided by change in x, determines if the lines are parallel, perpendicular, or neither, as follows:

If they are equal, the lines are parallel.

If their multiplication is of -1, they are perpendicular.

Otherwise, they are neither.

The first line, in standard form, is given by:

5y = x + 5

y = 0.2x + 1.

The slope is of m = 0.2.

For the second line, we have that:

25y = 5x - 75

y = 0.2x - 3

The slope is of m = 0.2.

Same slope, hence the lines are parallel.

What is the roots of f(x)=-x^2-6x-14

Nutka1998 [239]

Answer:

$x=-3\pm i \sqrt{5}$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Algebra II

Imaginary roots: √-1 = i

Step-by-step explanation:

Step 1: Define function

f(x) = -x² - 6x - 14

Step 2: Set up

Set equation equal to 0: -x² - 6x - 14 = 0
Factor out -1: -(x² + 6x + 14) = 0
Divide both sides by -1: x² + 6x + 14 = 0

Step 3: Define variables

a = 1

b = 6

c = 14

Step 4: Find roots

Substitute: $x=\frac{-6\pm\sqrt{6^2-4(1)(14)} }{2(1)}$
Exponents: $x=\frac{-6\pm\sqrt{36-4(1)(14)} }{2(1)}$
Multiply: $x=\frac{-6\pm\sqrt{36-56} }{2}$
Subtract: $x=\frac{-6\pm\sqrt{-20} }{2}$
Factor: $x=\frac{-6\pm\sqrt{-1} \sqrt{20} }{2}$
Simplify: $x=\frac{-6\pm2i \sqrt{5} }{2}$
Factor: $x=\frac{2(-3\pm i \sqrt{5} )}{2}$
Divide: $x=-3\pm i \sqrt{5}$
