I think that it’s 24 as I can see by the form it’s a Microsoft teams test form lol
Answer:
Option A.
Step-by-step explanation:
see the attached figure with letters to better understand the problem
In this problem we have a triangle with a circle inscribed in it
so
step 1
Find the length side B.C
substitute the given values
step 2
Find the length side C.D
Remember that
therefore
step 3
Find the length side E.D
we know that
substitute the given values
step 4
Find the length side E.F
Remember that
therefore
step 5
Find the length side A.F
Remember that
therefore
step 6
Find the perimeter
y = 6/5x -5
6/5 is your slope. Slope is always rise over run or y over x. -5 is the y- intercept. What is y when x is zero.

Answer:
<h2> 1) y = - 9</h2><h2> 2) y = -3x + 4</h2>
Step-by-step explanation:
<u><em>NUMBER ONE</em></u>
The slope of tghe line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (- 9 - (-9)) ÷ ( 5 - (-3))
= 0
The slope is zero because the y values of the line remain the same which means the line doesn't slope or rise.
We can now use the point-slope form to write the equation for this line:
y - y₁ = m(x - x₁)
y - (-9) = 0 (x - (-3))
y + 9 = 0
y = - 9
<em><u>NUMBER TWO</u></em>
For the slope-intercept form ( y = mx + c ) we need two main things: the slope (m) and the y-intercept (c)
slope = (y₂ - y₁) ÷ (x₂ - x₁) = (10 - (-11)) ÷ (-2 - 5)
= 21 ÷ (-7)
= - 3
Let's write the equation without the value of c. This will help us solve for it.
y = -3x + c
if we substitute in a point give (-2 , 10) we can find c
10 = -3 (-2) + c
10 = 6 + c
c = 10 -6
c = 4
⇒ the equation of the line is y = -3x + 4
