N = 22b+34
Plug in.
n = 22(2)+34=44+34=78
n = 22(3)+34=66+34=100
n = 22(5)+34=110+34=144
n = 22(7)+34=154+34=189
-10(x-7) -3x
= -10x + 70 - 3x
= -13x + 70
The answr is A
Answer:
22
Step-by-step explanation:
For this case we have the following function:

we have:

Where:

By definition, the discriminant of a quadratic equation is given by:

Two different real roots
Two equal real roots
: Two different complex roots
Substituting the values we have:


We have two equal real roots.
To find the intersections with the x axis, we do 

We apply the quadratic formula:

Substituting the values we have:

The intersection with the x axis is
Answer:

The intersection with the x axis is
