The inverse of the equation y = x² - 4, x≤ 0 is 
<h3>How to determine the inverse of the equation?</h3>
The equation is given as:
y = x² - 4, x≤ 0
Swap the x and y values
x = y² - 4
Add 4 to both sides
y² = x + 4
Take the square root of both sides
Hence, the inverse of the equation y = x² - 4, x≤ 0 is

Answer:
First term a = 3
Sum of first 20 term = 440
Step-by-step explanation:
Given:
8th term of AP = 17
12th term of AP = 25
Find:
First term a
Sum of first 20 term
Computation:
8th term of AP = 17
a + 7d = 17 ....... EQ1
12th term of AP = 25
a + 11d = 25 ...... EQ2
From EQ1 and EQ2
4d = 8
d = 2
a + 7d = 17
a + 7(2) = 17
First term a = 3
Sum of first 20 term
Sn = [n/2][2a + (n-1)d]
S20 = [20/2][(2)(3) + (20-1)2]
S20 = [10][(6) + 38]
S20 = [10][44]
S20 = 440
Sum of first 20 term = 440
Answer:
i think it's C.
Step-by-step explanation:
i really hope I'm right :/
1. given
2. corresponding parts theorem
- segments AB and DB are similar
and segments BC and BE are also similar. lastly the circle at angles C and E indicate that they are congruent
3. SSA similarly theorem
AB and BC are similar and BC and BE are similar and angle C and E are congruent. also the triangles are not congruent in length so that makes them similar.
i apologize if i am incorrect i like just learned this. have a great day and good luck on your studies
