Answer:

(x-10) (x+1) =0

x=10 x=-1

Step-by-step explanation:

x^2 -9x-10 =0

Factor

What two numbers multiply to -10 and add to -9

-10*1 = -10

-10+1=-9

(x-10) (x+1) =0

Using the zero product property

x-10 = 0 x+1=0

x-10+10=0+10 x+1-1=0-1

x=10 x=-1

These are the x intercepts

23 > 4n + 11 two step inequality

drek231 [11]

Solving the inequality: $23>4n+11$ we get $n$

Step-by-step explanation:

We need to solve the inequality: $23>4n+11$

Solving the inequality:

Switch the sides and reverse the inequality:

$4n+11$

Subtract 11 from both sides

$4n+11-11$

$4n$

Divide both sides by 4

$n$

$n$

So, solving the inequality: $23>4n+11$ we get $n$
