This is really hard to explain but i will try. The easiest one i see is 24 x 12, a good way to do it is by adding 12 to its self 24 times. the answer to that is 288.

Find the x- and y-intercepts of the following line: 4x − 3y = 12

Slav-nsk [51]

Answer:

x-intercept: (3,0)

y-intercept: (0,-4)

Step-by-step explanation:

To find the x and y-intercepts, we first need to understand what they are. X and y-intercepts are points on the line that passes through the x-axis and y-axis. When a point is an x-intercept, it passes through the x-axis. This means the x-coordinate is an integer, while the y-coordinate is always 0. This can be denoted by (x,0). When a point is a y-intercept, it passes through the y-axis. This means the y-coordinate is an integer, while the x-coordinate is always 0. This can be denoted by (0,y).

Now that we know what x and y-intercepts are, we can plug in x=0 and y=0 to find the intercepts.

x-intercept

4x-3y=12 [plug in y=0]

4x-3(0)=12 [multiply]

4x-0=12 [add both sides by 0]

4x=12 [divide both sides by 4]

x=3

---------------------------------------------------------------------------------------------------------

y-intercept

4x-3y=12 [plug in x=0]

4(0)-3y=12 [multiply]

0-3y=12 [subtract both sides by 0]

-3y=12 [divide both sides by -3]

y=-4

Therefore, the x-intercept is (3,0) and y-intercept is (0,-4).
