Y=mx+c
m1 x m2 = - 1 for perpendicular lines
m= -1/5
so now y= - 1/5x + c
Substitute given coordinate
3= (-1/5 × 3) +c
3= -3/5 + c
add 3/5 to both sides
2.6 (a.k.a 18/5) = y
So therefore:
y=(-x+18)/5
I think this is correct
Answer:
Solve it
Step-by-step explanation:
When you're asked to simplify an expression it means to solve it.
Hello There!
I got x/2 + 19 = 43
Hope This Helps You!
Good Luck :)

For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
