Y = 75 x (4x3)
y = 75 x 12
y = 900

A commercial jet can fly 868 miles in 2 hours with a tailwind but only 792 miles in 2 hours into a headwind. Find the speed of t

erik [133]

Answer:

The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the speed of the wind in miles per hour

y ----> the speed of the jet in still air in miles per hour

we know that

<em>With a tailwind</em>

$y+x=\frac{868}{2}$

$y+x=434$ ----> equation A

<em>With a headwind</em>

$y-x=\frac{792}{2}$

$y-x=396$ ----> equation B

solve the system of equations A and B by elimination

Adds equation A and equation B

$y+x=434\\y-x=396\\------\\y+y=434+396\\2y=830\\y=415$

<em>Find the value of x</em>

$y+x=434$

$415+x=434$

$x=434-415$

$x=19$

therefore

The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph

Which orderd pair is a solution to this equation? -2x-y=4

nevsk [136]

To find the ordered pair solution, you need to find the zero(s) (which are the x-values for which y is equal to zero). This is called the Zero Product Property. Here's the math:

-2x-y=4 convert the equation into slope form

-y=2x+4 multiply both sides by -1

y=-2x-4 convert into factored form

y=-2(x+2) now, we need to find what x equals that makes y equal zero

0=-2(x+2) replace y with zero

0/-2=x+2 divide both sides by -2

-2=x x=-2 when y=0

Therefore, the zero of the equation (aka the solution) is the ordered pair (-2,0).

Answer: (-2,0)

If you have access to a graphing calculator, you can just convert the equation to y=mx+b form and enter it as a function. The solution is wherever the graph intercepts the x-axis. Hope this helps!

An art project has an area of 63.6 square inches. What is the width, in inches, of the project?

Flura [38]

Answer:

The width of the art projects of area 63.6 square inches is 7.97 inches .

Step-by-step explanation:

Given as :

The area of the square art project = 63.6 square inches

Since The shape of the art project is square

So, The Area of square = A = side × side = side²

Now, let the measure of the width of art project = w inches

I.e side = w inches

or , A = side²

Or , A = w²

Or, 63.6 = w²

So, w = $\sqrt{63.6}$

I.e w = 7.97 inches

So, the width of the projects = w = 7.97 inches

Hence The width of the art projects of area 63.6 square inches is 7.97 inches . Answer
