Answer:
Step-by-step explanation:
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.Understand what multi-variable equations are. Two or more linear equations that are grouped together are called a system. That means that a system of linear equations is when two or more linear equations are being solved at the same time.[1] For example:
8x - 3y = -3
5x - 2y = -1
These are two linear equations that you must solve at the same time, meaning you must use both equations to solve both equations.
Answer:
$557.51
Step-by-step explanation:
A financial calculator tells you the payments are ...
on $80,000 at 4.75%: $417.32
on $20,000 at 7.525%: $140.19
Then the total monthly payment is ...
$417.32 +140.19 = $557.51
_____
You can use the amortization formula to find the payment (A) on principal P at interest rate r for t years to be ...
A = P(r/12)/(1 -(1+r/12)^(-12t))
I find it takes fewer keystrokes to enter the numbers into a financial calculator. Both give the same result.
Answer:
The answer is 8.
Step-by-step explanation:
Area = Length times width. Since division and multiplcation are inverse operations, we can do 24 divided by 3 to get 8, so to get the area of 24, you would do 8 x 3.
The graph of a single linear inequality splits the coordinate plane<span> into two regions. On one side lie all the solutions to the inequality. On the other side, there are no solutions. Consider the graph of the inequality </span>y<span> < 2</span>x<span> + 5.
</span>
Answer:
B
Step-by-step explanation:
The vertex of the parabola is (-1,-4)
So the axis of symetry is x=-1
