The average of ben’s three tests is 89. each test is worth 100 points. what score does he have to make on his 4th test to get an average of 90?

93

Step-by-step explanation:

Let's see what kind of equation we can make with this information.

90=((3×89)+x)/4

90×4=267+x

360-267=x=93

We can make this equation work because every test is worth 100 points.

answer: options

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.
