Beth's mother was upset with her because Beth's text messages from the previous month were 218% of the amount that their data plan allowed without incurring an extra charge. Beth's mother had to pay extra money for each text message over the allowance. Beth had 5,450 text messages last month. How many text messages is Beth allowed under her data plan with no extra cost?

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

multiple all that

step-by-step explanation:

27×17

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
