p(1) = 1

Let p(x) = x2 + bx = c

then, p(p(x)) = (x2 + bx + c)² + b(x2 + bx + c) + c

Sum of roots of p(p(x)) is given by = - (coefficient of x3/constant term)

= -2b/c2+bc+c = f(a,b) (say)

For critical points,

∂f/∂c = 0 and ∂f/∂b = 0

= 2b(2c+b+1)/c2+bc+c = 0 and - {( c2+bc+c)²- 2b (c)/ ( c2+bc+c)²}= 0

= b(2c+b+1) =0

= b= 0 or b= - (1+2c) = -(2c(c+1))/c2+bc+c = 0

If c=0 , b= -1 => c= 0 or c=-1

If c = -1 ,b = 1

thus we have the following possibility for (b,c)

(0,0) , (0,-1) , (-1,0) ,(1,-1).

At (0,0) f(0,0) = not defined

(0,-1) f(0,-1) = 0

(1,-1) f(1,-1) = 2

(-1,0) is not possible.

p(x) = (x2 +x-1)² + (x2 +x-1) -1

= p(1) = (1+1-1)² + (1+1-1) -1

= 1

Hence, p(1) = 1

Solve the equation.<br> \qquad r - 14 = 23r−14=23

Nesterboy [21]

Answer: $r=37$

Step-by-step explanation:

For this exercise it is important to remember that:

1. The Addition property of equality states that:

If $a=b$ , then $a+c=b+c$

2. The Subtraction property of equality states the following:

If $a=b$ , then $a-c=b-c$

3. The Division property of equality states that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

4. The Multiplication property of equality states the following:

If $a=b$ , then $a*c=b*c$

Then, having the following equation given in the exercise:

$r-14=23$

You need to solve for the variable "r" in order to find its value.

In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.

Therefore, you get the following solution:

$r-14+(14)=23+(14)\\\\r=37$

Type the equation that shows the pattern among this set of ordered pairs.

stich3 [128]

First find the slope between any two points:

$\sf Slope=\frac{y_2-y_1}{x_2-x_1}$

Where $\sf (x_1,y_1),(x_2,y_2)$ are the two points

So calculating the slope:

$\sf Slope=\frac{5-0}{2-1}=\frac{5}{1}=5$

So the slope is $\boxed{5}$

And our equation will be in the format of $\sf y=mx+b$
where $\sf m~ is~ the ~slope$ and $\sf b ~is~the~y-intercept$

So, now we have half of the equation:

$\sf y= 5x+b$

Now to calculate b, we can plug in a point $\sf (x,y)$ and solve for b.

So

$\sf y= 5x+b$

Lets use the point
$\sf (1,0) which ~is~in~the~form ~of ~(x,y)$

So:
$\sf 0=5(1)+b$

And then:
$\sf b=-5$

So our final equation is $\sf \boxed{y=5x-5}$
