Answer:

Step-by-step explanation:

The systems of linear equations can have:

1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.

2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system

3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.

Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.

A certain forest covers an area of 2600 km2. Suppose that each year this area decreases by 7.75%. What will the area be like aft

kakasveta [241]

Answer:

After 15 years, the area will be of 775.3 km²

Step-by-step explanation:

The equation for the area of the forest after t years has the following format.

$A(t) = A(0)(1-r)^{t}$

In which A(0) is the initial area and r is the yearly decrease rate.

A certain forest covers an area of 2600 km2.

This means that $A(0) = 2600$

Suppose that each year this area decreases by 7.75%.

This means that $r = 0.0775$

So

$A(t) = 2600(1-0.0775)^{t}$

$A(t) = 2600(0.9225)^{t}$

What will the area be like after 15 years?

This is $A(15)$

$A(t) = 2600(0.9225)^{t}$

$A(15) = 2600(0.9225)^{15} = 775.3$

After 15 years, the area will be of 775.3 km²

Answer:

See below in bold.

Step-by-step explanation:

10.

m < N = 180 - 53 - 44

= 83 degrees.

Using the Law of Sines:

LM / sin 83 = 14 / sin 44

LM = 14 sin 83 / sin 44

LM = 20.

11.

m < ABC = 1/2 * 192 = 96 degrees.
