Solve the equation for Y<br> 2x + y = -9

Westkost [7]

Alright, so first we'll have to get y on the other side

2x+y=-9

-y -y

+9 +9

2x+9=-y

Then divide is all by -1 so y is positive

-2x-9=y

Answer: -2x + 5y = 8

Step-by-step explanation:

Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y

Substitute the values of x and y from the given coordinate (6,4) to find the new constant, b, the y-intercept.

-2x + 5y = b

-2(6) + 5(4) = b

-12 + 20 = b

8 = b

Rewrite the original equation substituting the new b for the original -15

-2x + 5y = 8

An airplane heading due east has a velocity of 210 miles per hour. A wind is blowing from the north at 38 miles per hour. What i

Nimfa-mama [501]

Answer:

The resultant velocity of the airplane is 213.41 m/s.

Step-by-step explanation:

Given that,

Velocity of an airplane in east direction, $v_1=210\ mph$

Velocity of wind from the north, $v_2=38\ mph$

Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.

We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :

$v=\sqrt{v_1^2+v_2^2}$

$v=\sqrt{(210)^2+(38)^2}$

v = 213.41 m/s

So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.
