Varvara68 [4.7K]

Answer:

t = 1, but please check to see if I correctly interpreted your formatting.

Step-by-step explanation:

The format of the question is too confusing.

I'll assume this is the equation to be solved:

<u>16−2t=t+9+4t</u>

<u></u>

16−2t=t+9+4t

16-9 = t + 2t + 4t

7 = 7t

t = 1

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th
Rom4ik [11]

The linear equality represented by the graph as,\rm y > \frac{2}{3} x+3

<h3>What is the definition of inequality?</h3>

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

The slope of the dashed line is found as;

\rm m = \frac{y_2-y_1}{x_2-x_1}  \\\\\ m = \frac{3-1}{0+3} \\\\ m= \frac{2}{3}

The slope-intercept form is;

y=mx+c

Substitute the obtained value;

\rm  y = \frac{2}{3}x+3

We are aware that the given line Is a dashed line, and everything to its left is shadowed.

Hence, the linear equality is represented by the graph as,\rm y > \frac{2}{3} x+3
