11x10=110
110+40=150
150/6=25
25-8=17
17 is the number.
Undefined slope is rise/0
run is equal to 0
that means it doesn't go left or right
means it is vertcal
means it is x=somethig
(x,y)
(-6,4)
x=-6 is the equation
oh, forgot about standard form
standard form is
ax+by=c
so
x+0y=-6 would be the equation in standard form
36 hours use cross multiplication
Answer:
x^2 -2x + 1
Step-by-step explanation:
Think of a quadratic equation as
ax^2 + bx + c
x^2 -2x +
Comparing the two equations
a = 1 , b = -2, c = ?
c becomes the missing part
Divide b by 2
-2/2 = -1
square the result
-1^2
= 1 this is what to add to get a perfect square
x^2 -2x + 1
(x - 1)^2
Factor to find the roots.
(x+5)(x-1)=0
Proof:
5-1=4
5*-1=-5
Then apply the Zero Product Property.
(x+5)=0
x=-5
(x-1)=0
x=1
Roots: x=-5, x=1
