Y=6x4 + 7x2 and x = vw +1
belka [17]

Answer:

w=-1/6 or w=-3

Step-by-step explanation:

Substitute the value of x and y into the first equation and solve for w:

y=6x^4+7x^2\\10=6(\sqrt{w+1})^4+7(\sqrt{w+1})^2\\10=6(w+1)^2+7(w+1)\\10=6(w^2+2w+1)+7w+7\\10=6w^2+12w+6+7w+7\\0=6w^2+19w+3

Solve for w with the quadratic formula:

w=\frac{-b\±\sqrt{b^2-4ac}}{2a} \\w=\frac{-19\±\sqrt{19^2-4(6)(3)} }{2(6)}\\w=\frac{-19\±\sqrt{361-72}}{12} \\w=\frac{-19\±\sqrt{289} }{12} \\w=\frac{-19\±17}{12}

After simplifying, we get either w=-1/6 or w=-3.

Not sure if w needs to satisfy all conditions while maintaining everything as real numbers, because if w=-3, then x is an imaginary number. But both values work just as fine.

Which expression is equivalent to 60 - 3y - 9?
disa [49]

Answer:

the answer has to be 3(17-y)

Step-by-step explanation:

I'm pretty sure about that cause what I did at first is subtract the numbers.

<em>6</em><em>0</em><em>-3y-9</em>

=51-3y

factor our 3 from the expression.

3(17-y)
