Answer:
• The system of lines 6x+By=24 have x-intercepts of (4,0).
,
• The system of lines Ax-7y=21 have x-intercepts of (21/A,0).
Step-by-step explanation:
Part B
Given the equation:
Comparing with the general form of a straight line: Ax+By=C
The x-intercept is found using the formula below:
The system of lines 6x+By=24 have x-intercepts of (4,0).
Part C
Given the equation:
Comparing with the general form of a straight line: Ax+By=C
The x-intercept is found using the formula below:
The system of lines Ax-7y=21 have x-intercepts of (21/A,0).
