Answer:

Step-by-step explanation;

since they have something in common which is y,it is possible to subtract.we would be focusing more on the numbers than letters.The like term which is y just paves a way for these numbers to be subtracted.Hence, 6y -2y= 4y

or you can do it this way also

they have something in common which is y,so we factorise

y(6-2)

y(4)

hence y(4) also means 4 x y= 4y

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-7, x_2=-10,y_2=8$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )$
