Answer:

if y=mx+b then y=-4-2

Step-by-step explanation:

y-y1=m(x-x1) (point slope formula)

y-(-1)=-4(x-1)

turns into

y+1=-4x-1

move the 1 from the left to the right

y=-4x-2

What is the value of the expression 9+4n-1 when n = 3?

dangina [55]

Answer: 9+4n-1 = 20

We can solve this by substitution.
Replace n with the value given, 3 (remember 4n means 4 times n):
9 + 4*3 - 1
Then work it out using arithmetic
9+12-1
=20

(x + 1)^2 = 3x – 1 solving Quadratics ?

Deffense [45]

Step-by-step explanation:

$(x + 1)^{2} = 3x - 1 \\ \\ \therefore \: {x }^{2} + 2x + 1 = 3x - 1 \\ \\ \therefore \: {x }^{2} + 2x + 1 - 3x + 1 = 0\\ \\ \therefore \: {x }^{2} + 2x - 3x + 1 - 1 = 0 \\ \\ \therefore \: {x }^{2} - x = 0 \\ \\ \therefore \: x(x - 1) = 0 \\ \\ \therefore \: x = 0 \: \: or \: \: x - 1 = 0 \\ \\ \therefore \: x = 0 \: \: or \: \: x = 1 \\ \\ \huge{ \red{ \boxed{\therefore \: x = \{0, \: \: 1 \}}}}$
