What is the equation, in slope-intercept form, of the line that is perpendicular to the line y – 4 = –2/3 (x – 6) and passes thr

Gre4nikov [31]

Y-4=-2/3(x-6)
(y-(-2))=(-3/2)(x-(-2))
(y+2)=(-3/2)(x+2)
y-4=(-2/3)x+4
y=(-2/3)x+8
y+2=(-3/2)x-3
y=(-3/2)x-5
m2=(-3/2), (-2,-2)
y=(-3/2)x+b
(-2)=(-3/2)(-2)+b
-2=-3+b
1=b
d.) y=x+1, as the y-intercept is positive

What is the factored form of x2 − 4x − 5?

exis [7]

Answer:

$\large\boxed{x^2-4x-5=(x+1)(x-5)}$

Step-by-step explanation:

$\text{The factored form:}\\\\ax^2+bx+c=a(x-x_1)(x-x_2)\\\\x_1,\ x_2-the\ zeros\\==============================\\\\\text{We have}\ x^2-4x-5:\\\\x^2-4x-5=x^2+x-5x-5=x(x+1)-5(x+1)\\\\x^2-4x-5=(x+1)(x-5)$
