Here is the answer
10+1/7/2
remember if a fraction has 3 levels figure out two of them first: 10+1/7÷2
10+1/3.5
multiply both sides of the fraction by 2 to make the denominator a whole number
10+2/7
answer 10 2/7

Flying with the wind a plane went 198 mph. Flying into the same wind the plane only went 162 mph. Find the speed of the plane in

olganol [36]

Answer: speed of plane in still air is 180 miles per hour

speed of the wind is 18 miles per hour

Step-by-step explanation:

Flying with the wind, the plane went 198 miles per hour. This means if was flying in the same direction with the wind. This is same as the speed in still air because there was no opposition from the wind.

Flying into the same wind the plane only went 162 mph. This means that the plane flew against the wind

Let x = the speed of the plane

Let y = the speed of the wind

when flying with the wind,

x + y = 198 - - - - - - -1

When flying against the wind,

x - y = 162 - - - - - - - -2

Subtracting equation 2 from equation 1,

y - - y = 198 - 162

2y = 36

y = 36/2 = 18 miles per hour

x = 198 - y = 198 -18

x = 180 miles per hour

Anyone good with algebra 2??

A discontinuity is a point that cannot exist because the x-coordinate would cause a problem in the equation. If you have a polynomial in the denominator, you must find which values of x would cause the polynomial in the denominator to evaluate to zero. Since division by zero is undefined, that would cause a discontinuity.

Let's look at your function.

$f(x) = \dfrac{x^2 - 16}{6x - 24}$

$x^2 - 16$ is in the numerator. It is defined for every value of x. There is no problem there.

$6x - 24$ is in the denominator. This is a function defined for every value of x, but since it is in the denominator, we must exclude the x-value that would cause this polynomial to evaluate to zero.

We set it equal to zero and solve the equation for x.

$6x - 24 = 0$

$6x = 24$

$x = 4$

For x = 0, the denominator has a value of zero, so at this point there is a discontinuity in function f(x).

The answer is:

$x \ne 4$
