Answer:
Option (4)
Step-by-step explanation:
Given system of equations is,
y = -x²- 4x - 3
y = 2x + 5
To get the solution of the system of equations algebraically,
2x + 5 = -x²- 4x - 3
Now combine like terms onto one side of the equation.
-x² - (4x + 2x) - (3 + 5) = 0
x² + 6x + 8 = 0
Then factorize the equation,
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) =0
(x + 2) (x + 4) = 0
x = -2, 4
Option (4) is the answer.
Answer:
$23,700
Step-by-step explanation:
The compound interest formula can be helpful for this. Fill in the given values and solve for the unknown.
FV = P(1 +r/n)^(nt)
where r is the annual interest rate, n is the number of times interest is compounded in a year, t is the number of years, P is the amount invested, and FV is the future value of that investment.
$27,000 = P(1 +0.022/365)^(365·6) = 1.1411037P
P ≈ $23,700

The y intercept is simple <u>where the line touches the Y-Axis</u> (the one going up and down ↑↓)
In this case the y intercept is (+3)
Answer:
9/2
Step-by-step explanation:
9-3=6 and (1/3+1)=4/3
