Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
Equation of straight line is y=mx+c ,here m is slope in given question m is 1/4.
Hope it helps you.
I'm sorry I would help but I'm going to have to say b sorry for not being able to show

Answer: the number of possible values of a are 3 and 6
Explanation:
Since a is a divisor of 12
Then let’s see what are the divisor for 12
12= 6 x 2
12= 3 x 4
And we know that 3 is a factor of a
So if a was 3 then 3/3 is exactly 1
And if a was 6 then 6/3 is exactly 2 with no remainder
And 3 and 6 are also the divisor of 12
12/6=2
12/3=4
So a should be 3 and 6
