Step-by-step explanation:
Factor 5 5 out of 25 x 2 25x2.
5 ( 5 x 2 ) − 20 x y + 180 y 2 5(5x2)-20xy+180y2
Factor 5 5 out of − 20 x y -20xy.
5 ( 5 x 2 ) + 5 ( − 4 x y ) + 180 y 2 5(5x2)+5(-4xy)+180y2
Factor 5 5 out of 180 y 2 180y2. 5 ( 5 x 2 ) + 5 ( − 4 x y ) + 5 ( 36 y 2 ) 5(5x2)+5(-4xy)+5(36y2)
Factor 5 5 out of 5 ( 5 x 2 ) + 5 ( − 4 x y ) 5(5x2)+5(-4xy). 5 ( 5 x 2 − 4 x y ) + 5 ( 36 y 2 ) 5(5x2-4xy)+5(36y2)
Factor 5 5 out of 5 ( 5 x 2 − 4 x y ) + 5 ( 36 y 2 ) 5(5x2-4xy)+5(36y2). 5 ( 5 x 2 − 4 x y + 36 y 2 )
Step-by-step explanation:
point-slope form is
y - y1 = a(x - x1)
with a being the slope, and (x1,y1) being a point on the line.
the general form is
y = ax + b
a is again the slope. and b is the y-intercept (the y value when x = 0).
the slope is the ratio "y coordinate change / x coordinate change".
so, we need to find the slope of the original line :
x - 7y - 9 = 0
x - 9 = 7y
y = 1/7 x - 9/7
so, the original slope is 1/7.
the perpendicular slope turns the original slope upside-down and flips the sign.
so, it is
-7/1 = -7
the point slope form is
y - -4 = -7(x - 6)
y + 4 = -7(x - 6)
for the standard form we only need to do the multiplications and transform the equation into the above form :
y + 4 = -7(x - 6)
y + 4 = -7x + 42
y = -7x + 38
Make 275 t0 200 and 180 to 100 and 120 to 100
200+100+100=300
now turn 75 to 70 and 80 will stay 80 and 20 will stay 20
70+80+20=170
now add the 5 to 170= 175
now add 300 to 175 to get 475 which is ya answer
