Step-by-step explanation:

= x^2+6x+9-8=0

=x^2+6x+1=0

D=b^2-4ac

D= 36-4

D=32

x=-b±root D/2a

x=-6+4root2/2 , x = -6-4root2/2

simplify you get the least form...

Question is in picture below

klasskru [66]

Answer:

$\frac{y - 18}{x - 1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10 \\ y - 18 = 10(x - 1) = 10x - 10 \\ y = 10x + 18 - 10 = 10x + 8 \\ \boxed{f(x) = 10x + 8}$

<h2>A. is the right answer.</h2>

Help meeee<br> 16 and 17

Elanso [62]

For number 16
2x+6+x=180
3x+6=180
3x=180-6
3x=174
x=58

2(58)+6 =122

Linear pairs are 180 degree angles
Angle 1 = 58
Angle 2 = 122

If p(x) = x + 3, then what is the value of p(x) + p( - x)?

garik1379 [7]

Answer:

p(x) + p(-x) = 6 is

Step-by-step explanation:

In this question, we are tasked with calculating what p(x) + p(-x) will be

From the question, we know that p(x) = x + 3

Then p(-x) will be p(-x) = -x + 3

Thus p(x) + p(-x) = x + 3 -x + 3

p(x) + p(-x) = 3 + 3 = 6
