The biggest possible set is $\mathbb{R}$ .

The question to ask yourself is: is the operation $\lceil 2x \rceil -1$ not valid for some values of x ? ("not valid" = impossible to compute)
After removing all invalid values of x (if any), you have obtained the domain.

Answer:

c. -8

Step-by-step explanation:

Given:

$\frac{4b \div c}{1 - a}$

a = 5, b = 8, and c = 1

To evaluate, plug in the values into the expression given.

Thus:

$\frac{4(8) \div 1}{1 - 5}$

$\frac{32 \div 1}{1 - 5}$

$\frac{32}{-4}$

$\frac{8}{-1} = - 8$

judy has a piece of wood that is 4 5/8 feet long. she cuts off 3 feet 6 inches of the wood for a project. how much wood, in feet

Svet_ta [14]

there are 12 inches in 1 foot, so 6 inches is really just half a foot, thus 3'6" is really just 3.5' or 3½ feet.

now, let's convert those mixed fractions to improper fractions and then subtract, bearing in mind our LCD will be 8.

$\bf \stackrel{mixed}{4\frac{5}{8}}\implies \cfrac{4\cdot 8+5}{8}\implies \stackrel{improper}{\cfrac{45}{8}}~\hfill \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{45}{8}-\cfrac{7}{2}\implies \stackrel{\textit{using the LCD of 8}}{\cfrac{(1)45~~-~~(4)7}{8}}\implies \cfrac{45-28}{8}\implies \cfrac{17}{8}\implies 2\frac{1}{8}$
