Find the slopes of the asymptotes of the hyperbola with the following equation.
frosja888 [35]
You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36

36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3

To find the slope, divide a/b and you will get 2/3.

Determine which system below will produce infinitely many solutions.
vesna_86 [32]
First task:
To determine this we need to make difference between system that doesn't have solution and system that has infinite number of solution. If when solving equations we get   0 = 0 that means system has infinite number of equations.
If we get 0 = some number that means that system doesn't have solution.

Multiplying first equation of second system by 2 and adding it to second equation we get 0=0 which means that this system has infinite number of solutions.

Answer is second system

Second task:
For this we need to set a system of equations and solve it. System looks like this:
x + y = 224
x*12 + y*8=2520
-------------------------
x represents older than 18 and "y" 18 and younger than that.
first equation we multiply with -12 and sum it with second.
-4y = -168
y=168/4 = 42

Answer is 42.

jekas [21]

Answer:

144 inches

Step-by-step explanation:

If they are moving at the same speed and start at the same time, they have to go the same distance

That means they will meet in the middle

If they are 72 inches from the right side that means the middle is 72 inches from the right side

The road is 2 times 72 inches

2*72 = 144

144 inches
