Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)

Nathan is a recreational cyclist. He can travel 10 miles in one hour on his bicycle. Which graph represents the number of miles

PolarNik [594]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$1\ hr = 10\ miles$

Required

The graph that shows the number of miles in x hours

We have:

$1\ hr = 10\ miles$

Multiply both sides by x

$x * 1hr = 10miles * x$

$xhr=10x\ miles$

So, the function is:

$f(x) =10x$

$\\ \rm\Rrightarrow 2y=x-4$

$\\ \rm\Rrightarrow y=x/2-2$

m=1/2

Parallel lines have equal slope

Equation in point slope form

$\\ \rm\Rrightarrow y-4=1/2(x-1)$

$\\ \rm\Rrightarrow 2y-8=x-1$

$\\ \rm\Rrightarrow x-2y+7=0$

$\\ \rm\Rrightarrow 1/2y-3x=2$

$\\ \rm\Rrightarrow 1/2y=3x+2$

$\\ \rm\Rrightarrow y=6x+4$

Parallel lines have equal slope

Equation of line

$\\ \rm\Rrightarrow y-6=6(x+2)$

$\\ \rm\Rrightarrow y-6=6x+12$

$\\ \rm\Rrightarrow 6x-y+18=0$

$\\ \rm\Rrightarrow 1/k x+5=3y\implies y=x/3k+5/3$

m1=1/3k

$\\ \rm\Rrightarrow y=(2/k+3)x-6/(k+3)$

m2=2/k+3

Slopes remain same

$\\ \rm\Rrightarrow \dfrac{1}{3k}=\dfrac{2}{k+3}$

$\\ \rm\Rrightarrow k+3=6k$

$\\ \rm\Rrightarrow 5k=3$

$\\ \rm\Rrightarrow k=3/5$

What is the equation 3n+2=15

scoray [572]

Solution for 3n-2=15+3n equation:

Simplifying

3n + -2 = 15 + 3n

Reorder the terms:

-2 + 3n = 15 + 3n

Add '-3n' to each side of the equation.

-2 + 3n + -3n = 15 + 3n + -3n

Combine like terms: 3n + -3n = 0

-2 + 0 = 15 + 3n + -3n

-2 = 15 + 3n + -3n

Combine like terms: 3n + -3n = 0

-2 = 15 + 0

-2 = 15

Solving

-2 = 15

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
