Describe the error in solving for one of the variables in the linear system 4x + 3y = 8 and 2 2y = -13
X Х
4x + 3y = 8
x-2y=-13 Multiply by -4.
4x + 3y = 8
-4x+8y= -13
11y= -5
-5
y=
11
O The right side of the second equation was not multiplied by -4.
O The left side of the second equation was multiplied by 4.
O The expression 3y - 8y equals - 5y, not 1ly.
The expression 8 - (-13) equals 21. not -5.
Correct the error by solving for y

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
