the slope is undefined
Step-by-step explanation:
(-8,2) and (-8,-7)
x1= -8
x2 = -8
y1=2
y2= -7
m=y2-y1/x2-x1
m= -7-2/-8-(-8)
m= -9/0 ,so the slope is undefined
Answer:
undefined
Step-by-step explanation:
In both point, y-coordinate are same. So, the line is parallel to y-axis.
The slope of the line parallel to y-axis is undefined.

Explanation:
We have n = 5 sides. This means the interior angles sum up to...
S = 180(n-2)
S = 180(5-2)
S = 180(3)
S = 540
All five interior angles of this pentagon add up to 540 degrees.
what is the solution set of the equation (x-a) (x+b)=0
Answer:
Would it be x (squared) -ax +bx -a(b)
Or is it ax(squared) +bx +c?
If it isn't those then I think we need more information.

9. Divide 15x^7-45x^5/3x^4
10. Divide (3x-2)(x-4)-(x-4)(6-5x)/(4-x)(8x-1)
The rational equations after division is
a) A = ( 5x³ - 15x )
b) B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )
What is rational function equation?
A rational equation can be defined as an equation that involves at least one rational expression
A rational function is a function of the form f( x )=P( x ) / Q( x ) ,
f( x ) = P( x ) / Q( x ) , where P( x ) and Q( x ) are both polynomials.
A rational function f ( x )=P( x ) / Q( x )
f( x ) = P( x ) / Q( x ) may have a vertical asymptote
The domain is the set of all real numbers for which Q( x ) ≠ 0
Given data ,
a)
Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )
Let the second function be Q ( x ) = 3x⁴
On simplifying , we get
A = P ( x ) / Q ( x )
A = ( 15x⁷ - 45x⁵ ) / 3x⁴
A = 3x⁴ ( 5x³ - 15x ) / 3x⁴
On further simplification , we get
A = ( 5x³ - 15x )
b)
Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )
Let the second function be Q ( x ) = 3x⁴
On simplifying , we get
B = P ( x ) / Q ( x )
B = ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( 4 - x ) ( 8x - 1 )
B = - ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( x - 4 ) ( 8x - 1 )
On further simplification , we get
B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )
Hence , the rational equations are solved

You buy items costing $1000 and finance the cost with a fixed installment loan for 30
months at 4% simple interest per year.
a. What is the finance charge?
b. What is your monthly payment?
Answer:
The monthly payments will be $ 36.66, and the finance charge will be $ 100.
Step-by-step explanation:
Since I buy items costing $ 1000 and finance the cost with a fixed installment loan for 30 months at 4% simple interest per year, to determine what is the finance charge and what is my monthly payment, the following calculations must be performed:
1 year = 12 months
30 months / 12 = 2.5 years
(1000 x (1 + (0.04 x 2.5))) / 30 = X
(1000 x (1 + 0.1) / 30 = X
(1000 x 1.1) / 30 = X
1100/30 = X
36,666 = X
Therefore, the monthly payments will be $ 36.66, and the finance charge will be $ 100.

Step-by-step explanation:
lim┬(x→0)〖(√(1+x+x^2 )-1)/tan5x 〗
Evaluting the limand directly at x = 0 yields the indeterminate form 0/0, so we have a candidate for L'Hopital's rule. We get
[tex]\displaystyle\lim_{x\to0}\frac{\sqrt{1+x+x^2}-1}{\tan(5x)} = \lim_{x\to0}\frac{\frac{1+2x}{2\sqrt{1+x+x^2}}}{5\sec^2(5x)} = \frac{1+2\times0}{2\sqrt{1+0+0^2}\times5\sec^2(5\times0)} = \boxed{\dfrac{1}{10}}[/tex]
If you don't know about L'Hopital's rule, or are otherwise not allowed to use it, you can instead rely on algebraic manipulation and a well-known limit,
[tex]\displaystyle\lim_{x\to0}\frac{\sin(ax)}{ax}=\lim_{x\to0}\frac{ax}{\sin(ax)}=1[/tex]
where a ≠ 0. We write
[tex]\displaystyle\frac{\sqrt{1+x+x^2}-1}{\tan(5x)} = \frac{5x}{\sin(5x)}\times\frac{\cos(5x)}5\times\frac{\sqrt{1+x+x^2}-1}x[/tex]
The limit of a product is equal to the product of limits:
[tex]\displaystyle\lim_{x\to0}\frac{\sqrt{1+x+x^2}-1}{\tan(5x)} = \left(\lim_{x\to0}\frac{5x}{\sin(5x)}\right)\times\left(\lim_{x\to0}\frac{\cos(5x)}5\right)\times\left(\lim_{x\to0}\frac{\sqrt{1+x+x^2}-1}x\right)[/tex]
The first limit is 1 and the second limit is 1/5. For the remaining limit, multiply through the fraction by the conjugate of the numerator:
[tex]\dfrac{\sqrt{1+x+x^2}-1}x\times\dfrac{\sqrt{1+x+x^2}+1}{\sqrt{1+x+x^2}+1} = \dfrac{\left(\sqrt{1+x+x^2}\right)^2-1^2}{x\left(\sqrt{1+x+x^2}+1\right)} \\\cdots= \dfrac{x+x^2}{x\left(\sqrt{1+x+x^2}+1\right)} \\\cdots= \dfrac{1+x}{\sqrt{1+x+x^2}+1}[/tex]
The remaining limand is continuous at x = 0, and its limit is
[tex]\displaystyle\lim_{x\to0}\frac{1+x}{\sqrt{1+x+x^2}+1}=\frac{1+0}{\sqrt{1+0+0^2}+1}=\frac12[/tex]
and hence the original limit is again 1 × 1/5 × 1/2 = 1/10.

Find the perimeter of this figure to
the nearest hundredth. Use 3.14 to
approximate a.
P = [?] ft
Answer:
P = 40.56 ft
Step-by-step explanation:
The figure is composed of a rectangle and half circle
The perimeter of the figure = the length of the borders round the figure
= W + 2L + ½(perimeter of full circle)
W = 8 ft
L = 10 ft
½(perimeter of circle) = ½(πd) = ½(3.14*8)
= 12.56 ft
Plug in the values
Perimeter of the figure = 8 + 2(10) + 12.56
= 8 + 20 + 12.56
= 40.56 ft
