A, C. A is obviously correct because it’s the e same thing and C you combine like terms (2n+n=3n,2+4=6,=3n+6) it’s not B because it’s not 18, it’s not D because you’d get 3n+18 and it’s not E because you’d get 3n+12, meaning the only correct answers are A and C

Write the equation of a line in standard form that has x-intercept (P,0) and y-intercept (0,R).

ExtremeBDS [4]

Answer:

$Rx+Py=RP$

Step-by-step explanation:

The points on the straight line are (P, 0) and (0, R).

The slope would be

$m=\frac{R-0}{0-P}=-\frac{R}{P}$

And $b=R$ , because the y-intercept is at (0, R).

So, the equation of this line would be

$y=-\frac{R}{P} x+R$

Where we multiply the equation by $P$

$Py=-Rx+RP$

Therefore, the equation that represents this line is

$Rx+Py=RP$

<h2>So, the right answer is B.</h2>
