Answer:

yeah it si correct

Step-by-step explanation:

4x-5x²+6x³/2x=4x-5x²+3x²=4x-2x²

therefore the degree of the following polynomial is 2

A circular pool is surrounded by a circular walkway. The radius of the pool is y − 4 and the radius of the full circle formed by

TiliK225 [7]

A=πr²

pool=π(y-4)²=π(y²-8y+16)
total=π(y+4)²=π(y²+8y+16)

walkway=total-pool
walkway=π(y²+8y+16)-π(y²-8y+16)=
π(y²+8y+16-y²+8y-16)=
π(16y)=
16πy
first option is answer

which answer choice explains the pattern for how to find the slope using an equation in standard form?

Liono4ka [1.6K]

Question is using standard formula ax+by=c to find the slope by converting into slope intercept form y=mx+b

so we also need to convert ax+by=c into y=mx+b as shown below:

$ax+by=c$

$ax+by-ax=c-ax$

$by=-ax+c$

divide both sides by

$y=-\frac{a}{b}x+\frac{c}{b}$

Now compare it with y=mx+b, we get

$m=-\frac{a}{b}$

So using values of a and b, we can find the slope

compare given equation -5x+2y=15 with ax+by=c, we get:

a=-5, b=2

Now plug both into above formula

$m=-\frac{a}{b}$

$m=-\frac{-5}{2}$

$m=\frac{5}{2}$

Now matching these details with given choices we find that THIRD choice is the final answer.
