Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 9-3) / ( 2-2)
= 6/0
When we divide by zero, the result is undefined
This means the slope is undefined
Answer: 88
Step-by-step explanation:
Given
The first row has 16 seats
then there are 3 more seats in each row
this follows an AP with the first term 
and common difference 
So, no of seats in the 25 th row is
Thus, there are 88 seats in the 25 th row
Answer:
x=9
Step-by-step explanation:
First, distribute the 2 and each value in the parentheses.
2*x+2*5. This is the first half of the equation.
2*x+2*5= 3x+1 You can then simplify
2x+10=3x+1 Subtract 3x from both sides
(2x-3x)+10=(3x-3x[cancels out])+1
-x+10=1 Now subtract 10 from both sides
-x(10-10[cancels out to 0])=(1-10)
-x=-9 Since x is negative we need to solve for positive
x=9

Answer:
(2) 72°
Step-by-step explanation:
In this geometry, the angle at the tangent is half the measure of the intercepted arc.
∠CBD = (arc BD)/2 = 144°/2
∠CBD = 72°
__
<em>Additional comment</em>
Consider a point X anywhere on long arc BD. The inscribed angle at X will have half the measure of short arc BD, so will be 144°/2 = 72°. This is true regardless of the position of X on long arc BD. Now, consider that X might be arbitrarily close to point B. The angle at X is still 72°.
As X approaches B, the chord XB approaches a tangent to the circle at B. Effectively, this tangent geometry is a limiting case of inscribed angle geometry.
Two column proof is a logical argument arranged with a statement or reason
<u>Explanation:</u>
A logical argument in which each statement you make is supported by a statement that is accepted as correct or which is said to be true. They are said to be known as the two column proof.
A two-column proof comprises of a rundown of articulations, and the reasons why those announcements are valid. The announcements are in the left section and the reasons are in the correct segment. The announcements comprises of steps toward taking care of the issue.
