perpendicular lines have a slope that is a negative reciprocal
A) 4x-5y=5
subtract 4x
solve for y
-5y = -4x+5
divide by -5
y = 4/5 x+5 slope is 4/5 perpendicular slope is -5/4
y -y1 =m(x-x1) point slope form of a line
y-3 = -5/4 (x-5)
B) 5x+4y = 37
subtract 5x
4y =-5x +37
divide by 4
y =-5/4 x +37/4 slope is -5/4 perpendicular slope is 4/5
y -y1 =m(x-x1) point slope form of a line
y-3 = 4/5 (x-5)
C)4x+5y=5
subtract 4x
5y = -4x +5
divide by 5
y = -4/5 x +1
y =-4/5 x +1 slope is -4/5 perpendicular slope is 5/4
y -y1 =m(x-x1) point slope form of a line
y-3 = 5/4 (x-5)
D)5x-4y=8
subtract 5x
-4y = -5x+8
divide by -4
y = 5/4 x-2
y =5/4 x +-2 slope is 5/4 perpendicular slope is -4/5
y -y1 =m(x-x1) point slope form of a line
y-3 = -4/5 (x-5)
Answer:
2d-388 or 2(d-194)
Step-by-step explanation:
25(d-10)-23(d+6)
25d-250-23d-138
25d-23d-250-138
2d-250-138
2d-388
factor out or simplify,
you get 2(d-194)

Answer:

Step-by-step explanation:
1) Divide both sides by 2.

2) Simplify 4/2 to 2.

3) Add 4 to both sides.

4) Simplify 2 + 4 to 6.

5) Divide both sides by 2.

6) Simplify 6/2 to 3.

Answer:
x^2 -12x+36
Step-by-step explanation:
x^2 – 12x
Take the coefficient of x
-12
Divide by 2
-12/2 = 6
Square it
6^2 = 36
We need to add 36 to make x^2 -12x a perfect square trinomial
x^2 -12x+36
