How to solve for elimination

1 answer:

5 0

In most cases, you can do the inverse (opposite) operation on both sides of an equation to cancel out a certain value.

For example:

2x + 3y = 20
-2x + y = 4

This is a system of equations, just combine them to give you:

4y = 24

and divide both sides by 4:

y = 6

Sorry if this isn't what you were asking for, but the question was so vague, and this is what I assumed you were asking about, hopefully this helps regardless.

The function f(x)=1+1.5ln(x+1) models the average number of free-throws a basketball player can make consecutively during practi

UNO [17]

Answer:

402 days.

Step-by-step explanation:

f(x)=1+1.5ln(x+1)

When f() = 10 we have:

10 = 1 + 1.5ln (x + 1)

ln (x + 1) = (10-1) / 1.5 = 6

x + 1 = e^6

x = e^6 - 1 = 402.4.
