N^2+16n+60 over 36-n^2

svetoff [14.1K]

Factor
36-n^2 is difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
6^2-n^2=(6-n)(6+n)
factor

n^2+16n+60
find what 2 numbers multiply to 60 and add to 16
factors of 60=2,2,3,5
the numbers are 10 and 6
so factored out
(x+6)(x+10)
(x+6)=(6+x)

so the equation is
[(x+6)(x+10)]/[(6+x)(6-x)]=[(6+x)/(6+x)] times (x+10)/((6-x)=1 times (x+10)/(6-x)

the answer is (x+10)/(6-x)

CORRECT ANSWER GETS A BRAINLIEST

Alex787 [66]

Answer:

B. N(c) = (c-20)/n

Step-by-step explanation:

Given

C(n) = 10n+20

we have to find the inverse of this function

we have to express n in terms of C(n)

C(n) = 10n+20

we have make n independent of n and remove any other term containing on the side of n

subtracting 20 from LHS and RHS

C(n) - 20 = 10n+20 - 20

C(n) - 20 = 10n

dividing LHS and RHS by 10

C(n)/10 - 20/10 = 10n/10

=> n = (C(n) - 20)/10

Now given in problem, N(c) is no of bushels picked

and c is the cost of apple

so in function n = C(n) - 20/10

we replace C(n) with c

and n with N(c)

and then we have

N(c) = (c-20)/n Answer

In two or more complete sentences, explain how to solve the cube root equation, ^3√x+1 -2=0

IrinaVladis [17]

Explanation:

The first step is to figure out what the equation is. When unconventional math symbols are used, and when there are no grouping symbols identifying operands, that can be the most difficult step. Here, we think the equation is supposed to be ...

$\sqrt[3]{x+1}-2=0$

It usually works well in radical equations to isolate the radical. Here that would mean adding 2 to both sides of the equation, to undo the subtraction of 2.

$\sqrt[3]{x+1}=2$

Now, it is convenient to raise both sides of the equation to the 3rd power.

$x+1=2^3=8$

Finally, we can isolate the variable by undoing the addition of 1. We accomplish that by adding -1 to both sides of the equation.

$x=7$

The equation is solved. The solution is x = 7.

I would greatly appreciate if anyone could show me how to complete this problem.

Naya [18.7K]

Answer:

the best way to solve this is to have graph paper, so your numbers and points align. I have a model attached. the first point is hours slept 8. so on your graph go to 8 then across to 83, which is the test score. make a mark to represent this point. do this for all and it will create a line
