It's true, just draw the sides and you'll see there's no other angle you could get.

Find the domain for each expression. (1/x)+5 1/x X+5/x+5 X^2/x 7/(x-2)

wel

Using it's concept, it is found that the domain for the expressions is, respectively, given by:

$x \neq 0, x \neq 0, (-\infty, \infty), (-\infty, \infty), x \neq 2$

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values.

In a fraction, the denominator cannot be zero, hence:

The domain of the first two expressions is of $x \neq 0$ .

The domain of the last expression is of $x \neq 2$ .

The third expression can be simplified, as:

(x + 5)/(x + 5) = 1.

The same is true for the fourth, as:

x²/x = 1.

Neither has any restriction, hence their domain is all real numbers, represented by $(-\infty, \infty)$ .

At the fast food restaurant, an order of fries costs $1.05 and a drink costs $1.07. How much would it cost to get 3 orders of fr

trasher [3.6K]

Answer:

$7.43

Step-by-step explanation:

f (fries) = 1.01

d (drinks) = 1.07

1.05f + 1.07d = ?

To solve this problem, you need to replace the variable with the amount of each item.

1.05(3) + 1.07(4) = ?

Now we can solve by multiplying and adding:

3.15 + 4.28 = ?

3/4x < 33 Solve the inequality

slava [35]

answer:

x < 44

step-by-step explanation:

solve this like an equation

3/4x < 33

in order to solve this we can multiply this with the denominator first to cross out the fraction and be left with a whole number

3/4x < 33

3/4x(4) < 33(4)

3x < 132

x < 44

Please help me with ptomblem

Answer:

When $p^2 - 4p$ is subtracted from $p^2 + p - 6$ , the result is $5p - 6$ . To get $p - 9$ , subtract $4p + 3$ from the result.

Step-by-step explanation:

✔️Subtracting $p^2 - 4p$ from $p^2 + p - 6$ :

$(p^2 + p - 6) - (p^2 - 4p)$

$p^2 + p - 6 - p^2 + 4p$ (Distributive property)

Collect like terms

$p^2 - p^2 + p + 4p - 6$

$5p - 6$

✔️Subtracting $p - 9$ from $5p - 6$ :

$(5p - 6) - (p - 9)$

$5p - 6 - p + 9$ (distributive property)

Add like terms

$4p + 3$
