Mr torres tells his class of 24 that when they have completed their assignment they may read at the end of class 40% of the class is reading how many students still need to complete their assignment

14

Step-by-step explanation:

Given : Mr.  Torres tells his class of 24 that when they have completed their assignment they may read at the end of class.

40% of the class is reading , i.e. 40% of the class has completed their assignment.

We can rewrite 40% as 0.40  [We divide percent by 100 to convert into decimal]

Now, the number of students completed their assignment =

Now, the number of  students still need to complete their assignment will be :-

Hence, 14  students still need to complete their assignment.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
