Find the x- and y-intercepts of the equation 7x + 14y = 28.

The -intercept of the given equation is and the -intercept is .

Given:

The equation is:

To find:

The -intercept and -intercept of the given equation.

Explanation:

We have,

         ...(i)

Substitute in (i) to find the -intercept.

Substitute in (i) to find the -intercept.

Therefore, the -intercept of the given equation is and the -intercept is .

The x-intercept is  4  and the y-intercept is 2.

Step-by-step explanation:

The x is intercept is when y is 0 and the y intercept is when x is 0.So using this information you can put in 0 for x and another 0 for y and solve for the x and y intercepts.

7(0) + 14y = 28

0    + 14y = 28

   14y = 28

  y =  2

7x + 14(0) = 28

7x + 0 = 28

  7x = 28

x =  4

x+y = 29, 5x + 2y = 100

i'm guessing it was a multiple first option was the correct answer

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
