Write in standard form an equation for the line with slope 1/3 through<br> the point (2,-2).
Alexxandr [17]

Answer:

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3     Multiply through by 3:

3y + 6 = x - 2

x - 3y  =  6 + 2

x - 3y = 8  <---- Standard Form.

10. A company manufactures photo cells. It uses the expression
Murrr4er [49]

the expression (2x^3)^3 millimeters per second , after simplification we get 8x^9

Given

The company uses the expression (2x^3)^3 millimeters per second to calculate the maximum capacity with area x^3

Lets apply the property of exponents to simplify the expression  (2x^3)^3

We apply power property of exponents.

If we have exponent inside and outside the parenthesis then we multiply it

we distribute outside exponent inside the parenthesis

(a^nb^m)^k=a^{nk}b^{mk}

In the given expression , 2 has exponent 1

(2x^3)^3\\(2^1x^3)^3\\2^{1\cdot 3}x^{3 \cdot 3}\\2^3x^9\\8x^9

The simplified expression after applying the property is 8x^9
