Answer:

Step-by-step explanation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\(-5,1)\quad\implies\quad x_1=-5\,,\ \ y_1=1\\\\(-1,4)\quad\implies\quad x_2=-1\,,\ \ y_2=4\\\\d=\sqrt{(-1+5)^2+(4-1)^2}= \sqrt{4^2+3^2}=\sqrt{16+9}=\sqrt{25}=5$

The function m=30-3r represents the amount m (in dollars) of money you have after renting r video games.

san4es73 [151]

The domain of the equation are all the possible values of the independent variables that would make the equation reasonable, possible or true. In this item, the independent variable is r. This could take a value of 0 up to the point when m is equal to zero.
m = 30 - 3r = 0
r = 10

The domain is therefore [0, 10].

The range is the value of the dependent variable which would be from 0 to the point when no video game is played. This is, [0, 30].

The function is discrete because r and m cannot take every value in the number line.

Which of the following is equivalent to (16^3/2)^1/2? 6 8 12 64

Pani-rosa [81]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-------------------------------\\\\
\left( 16^{\frac{3}{2}} \right)^{\frac{1}{2}}\implies 16^{\frac{3}{2}\cdot \frac{1}{2}}\implies 16^{\frac{3}{4}}\qquad \boxed{16=2^4}\qquad (2^4)^{\frac{3}{4}}\implies 2^{4\cdot \frac{3}{4}}
\\\\\\
2^3\implies 8$

Consider the inequality -5(x+7)<-10 write inequality representing a solution for x

dedylja [7]

Perform indicated multiplication on left side first...

-5x-35<-10 add 35 to both sides

-5x<25 divide both sides by -5 (you must reverse sign because of division by a negative value too!)

x>5 or if you prefer...

x=(5, +oo)
