how to factor -9z^2 + 10z - 1 = 0 it’s been a while since i’ve been in school and i can’t seem to remember how please help

vichka [17]

Answer:

z = 1/9 and z = 1

Step-by-step explanation:

$-9 z^{2} + 10z - 1 = 0$

$(-9z+1)(z-1) = 0$

You can check the answer using foil method

Then,

$(-9z+1) = 0$

$-9z = -1$

$z = 1/9$

$(z-1) = 0$

$z = 1$

Answers:

$z = 1/9$

$z = 1$

How do you write an equation for (-5,-1), (0,-1)

lesya692 [45]

Both the points have a coordinate where y is -1, so the equation is simply -1

y=-1

however if you wanted to really show the working out, it looks like this:

y=mx+c

m=change in y/change in x

m=(-1-1)/(-5+0)=0

subsitute one of the coordinates into y=mx+c

-1=0+c

c=-1

so then y=-1
