Answer:
(- 4, - 12 ) , (4, 12 )
Step-by-step explanation:
Given the 2 equations
y = 3x → (1)
y = x² + 3x - 16 → (2)
Substitute y = x² + 3x - 16 into (1)
x² + 3x - 16 = 3x ( subtract 3x from both sides )
x² - 16 = 0 ( add 16 to both sides )
x² = 16 ( take the square root of both sides )
x = ± = ± 4
Substitute these values into (1) for corresponding values of y
x = - 4 : y = 3 × - 4 = - 12 ⇒ (- 4, - 12 )
x = 4 : y = 3 × 4 = 12 ⇒ (4, 12 )

Answer:
Camels has to pay $42 more as interest
Step-by-step explanation:
We are given that Carmela borrows $400 and will pay 5.25% yearly simple interest.
Principal = $400
Rate of interest = 5.25%
Time = 2 years
Formula :
So,
SI=42
She borrows the money for 4 years instead of 2 years,
So,
SI=84
Difference in interests = 84-42 = 42
Hence Camels has to pay $42 more as interest

Answer:
I think its D
Step-by-step explanation:
7x8x9 would equally 504 and 9x8x7 would also equall 504.So therefore your answer if I'm not mistaken would be D.
