Order of Operations- -6+(-30) divided by 5-(-2). Explain step by step
Reil [10]

Answer:

-36/7 or -5.14287

Step-by-step explanation:

so I would get rid of parentheses you do not need them

\frac{-6+-30}{5--2}=\frac{-36}{7}(because when two negative come before two numbers like -x-y they are being added but negative is present to the result of the sum, when one negative sign comes after a number and the other negative sign comes before a number, like x--y they are being added as well but negative is not present to the result of the sum)

-36/7=-5.1428

hope this helps!

Please help! Given the function problem
dedylja [7]

Answer:

B

Step-by-step explanation:

So we have the function:

f(x)=\frac{9}{5}x+32

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

x=\frac{9}{5}f^{-1}(x)+32

Subtract 32 from both sides:

x-32=\frac{9}{5}f^{-1}(x)

Multiply both sides by 5/9. The right side will cancel. Thus:

f^{-1}(x)=\frac{5}{9}(x-32)

Our answer is B.

And we're done!
