Alenkinab [10]

$\text {Hello! Let's Solve this Equation!}$

$\text {\underline {The First Step is to Subtract 3p}}$

$\text {24p-66-3p=3p+43-3p}$

$\text {Your New Problem Is: 21p-66=43}$

$\text {\underline {The Next Step Is to Add 66}}$

$\text {21p-66+66=43+66}$

$\text {Your New Problem Is: 21p=109}$

$\text {\underline {The Final Step is to Divide 21}}$

$\text {21p/21=109/21}$

$\text {Your Answer Would Be:}$

$\fbox {p=109/21}$

$\text {Best of Luck!}$

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.

The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?

luda_lava [24]

<h3>Answer: Choice C. (-1, -5)</h3>

Explanation:

The reflection rule we use is

$(x,y) \to (-x, y)$

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore, $(1, -5) \to (-1, -5)$

Expand and simplify x(x+2)x+(x+3)

Natasha_Volkova [10]

To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
