Answer:
= x² + 7x + 70
Step-by-step explanation:
-7x - 60 = x² + 10
= -x² - 7x - 60 - 10
= -x² - 7x - 70
= x² + 7x + 70
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
Explanation:
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
Answer:
315881.53
Step-by-step explanation:
We first need to figure out how long it takes for the money to triple
let x= number of years it takes for the money to tirple
Now plug that value into the continously compounding formula
Which rounds to
315881.53
