Answer: w^2-22w+19

Step-by-step explanation:

X=7w+4w-6\\Y=w^2-11w+13\\

(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

-1(-w^2+22w-19)\\=w^2-22w+19

Trava [24]

Answer:

a=22,\\b=31,\\c=13

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}

16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}

34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}

If f(x)=(1/8)(8^x) what is f(3)?<br> A. 1/512<br> B. 1/64<br> C. 512<br> D. 64
cestrela7 [59]
Hi there!

Let's solve this problem step by step!
f(x) =  \frac{1}{8} (8 {}^{x})

To find f(3) we must substitute x = 3 into the formula.
f(3) =  \frac{1}{8} (8 {}^{3} )

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.

Work out the exponents inside the parenthesis first.
f(3) =  \frac{1}{8}  \times 512

And finally multiply.
f(3) =  \frac{1}{8}  \times  \frac{512}{1}  =  \frac{512}{8}  = 64

Hence, the answer is D. 64.
~ Hope this helps you!
