Answer:
m = 4
Step-by-step explanation:
Substitute x = 1, y = 1 , that is(1,1) into the equation
1 - 5 = m(1 - 2)
- 4 = - m ( multiply both sides by - 1 )
m = 4
1092 divided by 28 and you will get 42
And 1092 divided by 130 you will get 8.4
Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus
9 is the blank.
(a+b)^2 = a^2 + 2ab + b^2
a = x
b = 3
(x+3)^2 = x^2 + 6x + 9
