When solving -1/8 (x + 35) = −7, what is the correct sequence of operations?

mariarad [96]

<u>ANSWER: </u>

Division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$

<u>SOLUTION: </u>

Given, equation is $-\frac{1}{8}(x+35)=-7$

We need to solve the given equation in correct sequential order.

So, let us follow the BODMAS rule.

BODMAS means sequence of operations are brackets, orders, division, multiplication, addition, subtraction

Now,

$-\frac{1}{8}(x+35)=-7$

As the term in brackets cannot be processed further we can go for next term.

Now the division operation has to be done first according to BODMAS

- 0.125(x+35)= -7

Multiplication comes second in order.

-0.125x+4.375= -7

On rearranging the terms, we get

-0.125x+4.375+7=0

Now perform addition according to BODMAS

-0.125x+11.375=0

0.125x=11.375

$x=\frac{11.375}{0.125}=91$

Hence division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$

Write a polynomial, f(x), with degree 5 that has zeros 1, √2, -√2, √3, -√3.

just olya [345]

The get (x-1)(x-√2)(x+√2)(x-√3)(x+√3).

Expanding, you get x^5-x^4-5x^3+5x^2+6x-6.

Kobotan [32]

Hello,

the graph of f(x) is joint here.
It has a form of "V" with (13,11) like vertex;
It is a minimum.
It is composed of 2 half straight lines y=-x-2 (for x<13) and y=x+2 (for x>13)
