Answer:
a₆ = 972
Step-by-step explanation:
Given a₁ = 4 and 
= 3
, then
a₂ = 3a₁ = 3 × 4 = 12
a₃ = 3a₂ = 3 × 12 = 36
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
a₆ = 3a₅ = 3 × 324 = 972
The x-coordinates need to be subtracted and the y-coordinates need to be subtracted.
The x-coordinates are 6 and 2.
Their subtraction is 6 - 2.
Kendra did this correctly.
The y-coordinates are 8 and -3.
Their subtraction is 8 - (-3) = 8 + 3 = 11.
Kendra did this incorrectly. She should have had 8 - (-3) = 8 + 3 = 11.
Then she'd square 11.
Instead, she subtracted 8 and -3 incorrectly and got 8 - 3 = 5.
Then she squared 5 when she should have squared 11.
When the discriminatn is negative, then there aer no real roots
answer is A and D
Answer:
x = 10
Step-by-step explanation:
-1/2x+2=-x+7
Add x to each side
-1/2x+x+2=-x+x+7
Combine like terms
1/2x +2 = 7
Subtract 2 from each side
1/2x+2-2 = 7-2
1/2x =5
2*1/2x = 5*2
x = 10
