Answer:

C infinitely many solutions

Step-by-step explanation:

multiply second equation by -3

-3 × (4x + 3y) = -12 ➡ -12x - 9y = 36 now add this to second equation

12x + 9y -12x -9y = -36 + 36 ➡0 = 0

we say there's infinite solutions because whatever value you write for x and/or y there will be a solution.

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>
