Answer:

Step-by-step explanation:

1. Honestly, my course of action, if allowed to, would be to use my graphing calculator. Obviously, you can graph the first equation but the second one requires some rearranging, keeping in mind that we are isolating the y.

$2y-2x=10$

$2y=2x+10$

$y=x+5$

So now we have an equation of the line. Simply enter both of these equations into your graphing calculator and you're all set.

I hope this helps!

What is the product of -6x3y5 and -4y2? A. -24x3y7 B. -24x3y10 C. 24x3y7 D. 24x3y10

Leto [7]

Answer:

Step-by-step explanation:

So we have the product of:

$(-6x^3y^5)\cdot(-4y^2)$

Multiply. Combine like terms:

$=(-6\cdot -4)(x^3)(y^5\cdot y^2)$

The first term is 24.

The second term stays as it is.

The third term will equate to y^7. Recall how to multiply exponents. The base stays constant and you add the exponents. Thus:

$=24x^3y^7$

Our answer is C.

And we're done!

It has been reported that men are more likely than women to participate in online auctions. In a recent survey, 65% of responde

vivado [14]

Answer:

0.84 or 84%

Step-by-step explanation:

Let 'n' be number of people who took the survey, the number of men who answered the survey is 0.45n. The number of men who answered the survey and have participated in online auctions is 0.38n. Therefore, choosing from the population of men who took the survey (0.45n) the probability that a respondent had participated in an online auction is:

$P =\frac{0.38n}{0.45n}\\P=0.84$

What is the value of the expression when n=3 6(n^2+2)/n 16 22 30 66

Kipish [7]

The correct answer is: [B]: " 22 " .
_________________________________________________________
Explanation:
_________________________________________________________
Given:
_________________________________________________________

$\frac{6(n^2 + 2)}{3}$ ;

Solve when: "n = 3" ;

Rewrite the expression; substituting "3" for all values of "n" ; as follows:

→ $\frac{6(3^2+2)}{3}$ ;

The "6" cancels out to "2" ; & the "3" cancels out to "1" ;

→ {since: " {6 ÷ 3 = 2}" ; and since: " {2 ÷ 2 = 1}" .
_________________________________________________________
→ Since the "denominator" is "1" ; and any value, divided by "1"; results in that original value; we can eliminate the denominator.

→ Now, we can rewrite the expression as:
_________________________________________________________
→ " 2(3² + 2)" ;

= 2(9 + 2) ;

= 2(11) ;

= " 22 " .
_________________________________________________________
→ The answer is: " 22 " ; which is: Answer choice: [B]: " 22 " .

What is the length of side s of the square shown below?

zaharov [31]

Answer:

$A.\: 4 \sqrt{2}$

Step-by-step explanation:

$\sin \: 45 \degree = \frac{s}{8} \\ \\ \implies \: \frac{1}{ \sqrt{2} } = \frac{s}{8} \\ \\ \implies \: s = \frac{8}{ \sqrt{2} } = \frac{8 \sqrt{2}}{2} \\ \\ \implies \: \huge \: s = 4 \sqrt{2}$
