Answer:
The answer would be D, -(-4)
Step-by-step explanation:
This is because two negatives equal a positive.
Answer:
a = - 1
Step-by-step explanation:
given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Then the x-coordinate of the vertex is
• 
= - 
The line of symmetry passes through the parabola, hence x-coordinate is 4
y = ax² + 8x - 3 is in standard form
with a = a, b = 8 and c = - 3, hence
- 
= 4 ( multiply both sides by 2a
- 8 = 8a ( divide both sides by 8 )
a = - 1
Answer:
you would distribute the 10 to the 2 so 20x + 80y - 60
Step-by-step explanation:
you distribute the 10 to each of the numbers
Answer: 8 quartets can be formed.
1 singer will be left over.
Step-by-step explanation:
A quartet is a group of 4 members.
Given: The women'schorus has 33 members.
The number of quartets can be formed = (Total members) divided by (4)
= 33 ÷ 4
By solving 33 ÷ 4 we get 8 as quotient and remainder as 1 such that
33 = 4 x 8 +1
Hence, 8 quartets can be formed.
1 singer will be left over.
