Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

Convert 6 10/36 to an improper fraction in lowest terms
Nata [24]

ANSWER

\frac{113}{18}

EXPLANATION

We want to convert

6 \frac{10}{36}

to improper fraction.

Let us first reduce the fractional part to get;

6 \frac{5}{18}

We now multiply 6 by 18 and add 5 and then express the result over 18.

This will give us;

=  \frac{6 \times 18 + 5}{18}

=  \frac{108 + 5}{18}

=  \frac{113}{18}
