$\frac{1}{3}$ x-1

Step-by-step explanation:

( $\frac{5}{6}$ x-7)-( $\frac{1}{2}$ x-6) =

The - sign before 6 is turned into a + sign when the bracket is removed because the arithmetic operation before the bracket is - and two - makes the second - turn into a + (It's a rule I can't rlly explain it well but yea)

$\frac{5}{6}$ x-7- $\frac{1}{2}$ x+6 = $\frac{5}{6}$ x-1- $\frac{1}{2}$ x

-7+6 makes it a -1.

$\frac{5}{6}$ x- $\frac{1}{2}$ x-1 = $\frac{5}{6}$ x- $\frac{3}{6}$ x-1

To make the denominator of the two fractions the same, I multiplied the second fraction by 3 so that both denominators are 6.

$\frac{5}{6}$ x- $\frac{3}{6}$ x-1 = $\frac{2}{6}$ x-1

After making the denominator the same, I can directly do the equation for the numerators (5-3=2) and keep the denominator the same.

$\frac{2}{6}$ x-1 = $\frac{1}{3}$ x-1

Since 2/6 has a common factor which is 2, I can divide both the numerators and denominators so that the fraction can be simplified further into 1/3, its simplest form.

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
