ALEKS Exam Questions and Answers
A+ Graded (2025)
What .is .absolute .value? .- .CORRECT .ANSWER-distance .from .zero .on .a .number
.line
if .you .get .a .negative .absolute .value, .why .is .it .said .to .not .have .a .solution? .-
.CORRECT .ANSWER-because .distance .can't .be .negative
What .are .integers? .- .CORRECT .ANSWER-all .whole .negative .and .positive
.numbers
When .should .you .switch .the .sign .on .an .inequality? .- .CORRECT .ANSWER-when
.you're .dividing .or .multiplying .by .a .negative .number
Why .is .it .that .you .can .have .a .both .negative .and .positive .solution .for .absolute
.value? .- .CORRECT .ANSWER-because .if .your .main .solution .is .positive, .if .u
.plug .that .back .into .the .absolute .value .bars, .you'll .still .get .a .positive .number.
.absolute .value .always .has .to .be .positive, .so .if .you .get .a .negative .number .its
.not .the .absolute .value. .remember .this .numbers .that .u .get .are .the .result, .not
.the .ones .u .plug .in
What .to .do .when .vertical .shifting .a .graph? .- .CORRECT .ANSWER-take .what's .in
.the .parentheses .and .put .it .equal .to .0, .then .translate .left .or .right .that .exact
.amount
when .you .get .0=0 .as .the .solution .to .an .expression, .what .does .this .mean? .-
.CORRECT .ANSWER-all .real .numbers .are .solutions, .because .a .real .number
.equals .a .real .number
when .you .get .0=-3 .as .the .solution, .what .does .this .mean? .- .CORRECT
.ANSWER-there's .no .solution
a .pair .of .coordinates .represent .a .function .if .what? .- .CORRECT .ANSWER-they
.don't .have .the .same .x-coordinates
if .you .have .a .negative .exponent .as .a .denominator .and .one .as .the .numerator,
.what .rule .can .you .follow .to .make .the .numerator .positive? .- .CORRECT
.ANSWER-move .the .negative .exponent .to .the .numerator .and .make .it .positive
, when .using .elimination, .what .is .the .first .step .you .have .to .do? .- .CORRECT
.ANSWER-isolate .one .of .the .variables,you .can .do .this .by .multiplying .both
.equations .by .different .variables .because .they're .not .equal .to .each .other, .so
.you .can .do .that .and .once .its .all .in .order .just .add .down
what .is .the .formula .for .volume .of .a .cylinder? .- .CORRECT .ANSWER-V=pi .r
.squared .h
what .units .is .volume .always .in? .- .CORRECT .ANSWER-cubed
how .do .u .find .the .perfect .square .term? .- .CORRECT .ANSWER-take .half .of .the
.coefficient .term, .then .square .it
what's .something .to .keep .in .mind .when .you're .determining .the .LCD .for .one
.fraction .on .one .side .of .the .equation .and .one .on .the .other? .- .CORRECT
.ANSWER-you .have .to .multiply .both .sides .of .the .LCD .even .if .one .side .already
.has .it, .because .they're .equal .to .each .other
what .should .u .remember .when .solving .an .absolute .value .equation .that .is
.different .from .an .absolute .value .inequality? .- .CORRECT .ANSWER-if .the
.solution .to .the .equation .is .bigger .than .0, .then .you .split .them .up .and .consider
.both .solutions, .if .the .solution .is .already .less .than .0, .it .has .no .solutions
.because .its .already .negative
the .difference .between .finding .a .union .of .a .set .and .the .intersection .of .a .set? .-
.CORRECT .ANSWER-set .of .all .elements .that .are .in .set .a .or .set .b .for .union, .set
.of .all .elements .that .are .in .set .a .and .set .b .for .intersection
what .is .a .rational .number? .- .CORRECT .ANSWER-a .ratio .of .two .integers, .also
.fractions .and .squares .that .equal .integers
what .is .formula .for .area .of .a .semicircle .- .CORRECT .ANSWER-a=1/2r^2
what .is .formula .for .area .of .a .triangle .- .CORRECT .ANSWER-1/2bh
what .do .u .do .to .find .the .roots? .- .CORRECT .ANSWER-get .the .expression .into
.quadratic .form, .get .solutions .and .set .equal .to .0
what .happens .if .you .dont .get .the .two .identical .binomials .by .grouping? .-
.CORRECT .ANSWER-either .try .grouping .them .differently .or .it .cant .be .factored
.by .grouping
whats .one .thing .u .should .add .in .when .doing .grouping? .- .CORRECT .ANSWER-if
.you .have .to .factor .by .1 .to .get .the .identical .binomial, .then .you .have .to .add .a .+1
what .is .the .formula .for .circumference .of .a .circle? .- .CORRECT .ANSWER-C= .pi .x
.d
