A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.

B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20

Add equations
x=5

Plug x in
5+y=20
y=15

Final answer: 5 cheese wafers, 15 chocolate wafers

Which inequality is represented by this graph? 0 - 345> x O 0 -34.5 0 -355 cx​
julia-pushkina [17]

Answer:

Step-by-step explanation:

If x is the white dot on the graph:

From what it looks like, x is right between -35 and -34 x (which is -35.5).

If that is the case then none of the answers are correct since -35.5 is <u>equal or less</u> than x. (the sign looks like this:  "\leq" )

But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.

Solve for the equation for all x values by completing the square x^2 - 27= 67
navik [9.2K]

Answer:

The solutions for the equation x^2\:-\:27=\:67 are x=\sqrt{94},\:x=-\sqrt{94}.

Step-by-step explanation:

To find the solutions for the equation x^2\:-\:27=\:67 you must:

\mathrm{Add\:}27\mathrm{\:to\:both\:sides}\\\\x^2-27+27=67+27

\mathrm{Simplify}\\\\x^2=94

\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\x=\sqrt{94},\:x=-\sqrt{94}
