Answer:

$M\cup N$ ={6,7,8,9,10}.

Step-by-step explanation:

We have an empty set: M={} and the set N={6,7,8,9,10}.

The union of these two sets are elements in M or N or both.

Since the M is a null set, $M\cup N=N$

Therefore: $M\cup N$ ={6,7,8,9,10}.

The union for the given sets is {6,7,8,9,10}.

How do you Subtract 9x^2 + 22x - 46 from 12x^2 - 8x + 12.

Luba_88 [7]

Subtract the $x^2$ terms from each other, then the $x$ terms, then the ones without any $x$ whatsoever.

$(12x^2 - 8x + 12) - (9x^2 +22x-46)$

First, we'll subtract $9x^2$ from $12x^2$

$12x^2-9x^2- = 3x^2$

Result: $3x^2$

Next, we'll subtract $22x$ from $-8x$

$-8x - 22x = -30x$

Result: $-30x$

Finally, we'll subtract $-46$ from $12$

$12-(-46) = 12+46 = 58$

Result: $58$

Now, we can add these 3 results together.

First, we had $3x^2$ , then $-30x$ , and finally $58$ .

Thus, our subtraction of

$(12x^2 - 8x + 12) - (9x^2 +22x-46)$

equals

$3x^2-30x+58$

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

jeka94

Danielle earned $979.75 last week.

Step-by-step explanation:

Base salary = $625 per week

Commission = 8.25%

Cost of items sold = $4300

Amount of commission = $8.25\% \of \cost\ of\ sold\ items$

$Amount\ of\ commission=\frac{8.25}{100}*4300\\Amount\ of\ commission=\frac{35475}{100}\\Amount\ of\ commission=\$354.75$

Total earning last week = Base salary per week + amount of commission

$Total\ earning = 625+354.75\\Total\ earning=\$979.75$

Danielle earned $979.75 last week.
