write a system of equations for the problem, and then solve the system. if a plane can travel 340 miles per hour with the wind o
Dennis_Churaev [7]

Answer:

The speed of plane = 40 m/s

The speed of the wind = 300 m/s

Step-by-step explanation:

Let the speed of the plane = Y

And the speed of the wind = X

If the plane then travel 340 miles per hour with the wind, that means the plane and the wind are moving in the same direction. Therefore,

X + Y = 340 ..... ( 1 )

Also, 260 miles per hour against the wind. That is, the plane is moving opposite to the direction of the wind. Therefore,

X - Y = 260 ..... ( 2 )

Solve the two equations simultaneously by addition. That will eliminate Y

X + Y = 340

X - Y = 260

2X = 600

X = 600/2

X = 300 m/s

Substitutes X in equation (1)

300 + Y = 340

Make Y the subject of formula by collecting the like terms

Y = 340 - 300

Y = 40 m/s

Therefore, the speed of the plane is 40 m/s. While the speed of the wind is 300 m/s.

Trying to find the y-intercept and got -24. But the graph given doesn't have a number on the y-axis going all the way down to -2
mario62 [17]

Answer:

y = 6x - 24

Step-by-step explanation:

Slope intercept form: y = mx + b.

Fill in x, y, and the slope to solve for b as follows:

First find the slope.

60 - 6

14 - 5

54/9

Slope = 6

y = 6x + b

(6) = 6(5) + b

6 = 30 + b

Subtract 30 from both sides.

-24 = b

y = 6x - 24

Do 23 and 100 have a common denominater
musickatia [10]
No, 23 is a prime number. The only factors of 23 is 1 and 23. For two numbers to have a common denominator, they must have a similar factor.

Simplify the following rational expression. Use absolute value symbols when needed.<br> 3 √216/1728
bagirrra123 [75]

Answer:

1/2

Step-by-step explanation:

Absolute value symbols are only needed in certain cases when finding the nth root of a number when n is even. For example, the 4th root of (-2) ^ 20 is |(-2) ^ 5| or 32. To find a cube​ root, work backwards. Find a number whose cube is the radicand.  

Notice that the radical expression is of the form n√b​, where b is a real number and n is a positive integer. This expression can be written as an exponential equation of the form a^n = b​, where a is also a real number.

Write 3 √216/1728  as an exponential equation of the form a^n = b

a^3 = 216/1728

Because n is​ odd, there is only one value of a that makes the equation true. In this​ case, a will be a fraction.  Determine the numerator of a. Find the number​ that, when​ cubed, is 216.

(6)^3 = 216

Now determine the denominator of a. Find the number​ that, when​ cubed, is 1728.

(12)^3 = 1728

Use the numerator and denominator found above to complete the equation a^3 = 216/1728. . Since n is​ odd, absolute value symbols are not necessary.

(6/12)^3 = 216/1728

​Finally, simplify this value of a.

6/12 = 1/2

Therefore, 3 √216/1728 = 1/2
