Which statement is true about the solution to the set of equations? (5 points)
There are infinitely many solutions.
There are two solutions.
There is one solution.
There is no solution.
A linear
B quadratic
C exponential
D cubic
Answer:
(-3,-5) because the point satisfies both equations.
Step-by-step explanation:
We are given that two lines A and B
Line A:
Line B:
We have to find the solution of the given system of equation and explain .
Using elimination method
Eliminate y by subtracting equation first from equation second then, we get
Substitute x=-3 in equation first
Hence, the solution of given system of equation is (-3,-5).
Substitute x=-3 and y=-5 in first equation then , we get
LHS=RHS
Hence, (-3,-5) satisfies the the equation.
Substitute x=-3 and y=-5 in second equation
Then, we get
LHS=RHS
Hence, (-3,-5) satisfies the equation.
Hence, (-3,-5) is the solution of the system of equations because the point satisfies both equations.
Answer:(-3,-5) because the point satisfies both equations.
Answer:38.5
Step-by-step explanation:
The amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
It is given that:
An investment account earns 4% per year compounded annually if the initial investment was $4000.
P = 4000
r = 4% = 0.04
t = 3
n = 1
Plug all the values in the formula, and we get:
A = 4000(1 + 0.04)³
A = $4499.45
Thus, the amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.
