Answer:
Step-by-step explanation:
38
Ans: B
The method (a^2-b^2) is considered as one of the many ways of factorisation.
Hope this can help.
5+2(6)-6/35+12-6/35+12-217-215
Multiply through by 7:-
3x - 14 = 105
3x = 119
x =119/3 = 39 2/3
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
