(2, -5) and (7, -10)
x² – 3x – 3 = 0
First, add 3 to both sides
x² – 3x – 3 (+3)= 0 (+3)
x² – 3x = 3
Solve for a. 2ax = -3x; a = -3/2
x² - 3x + (-3/2)² = 3 + (-3/2)²
Simplify
x² - 3x + (-3/2)² = 21/4
Complete the square
(3 - 3/2)² = 21/4
solve:
x - 3/2 = √(21/4); x = (√21 + 3)/2
x - 3/2 = -√(21/4); x = ((-√21) + 3)/2
Answers:
x = ((√21) + 3)/2 & x = ((-√21) + 3)/2
hope this helps
Hello!
I believe the answer is X = -0.79, 3.79.( rounded to nearest hundredth )
I hope it helps!
Answer:
A and D would be the correct answers
Step-by-step explanation:
Answer:
If a set has 1,024 subsets,then it has 10 elements
Step-by-step explanation:
If A is a set containing n elements then total numbers of subsets of A are
Here, we are given that
We know that
i.e.
Hence, n=10
Hence, If a set has 1,024 subsets,then it has 10 elements
