Yeah, these are tough.

When the plane is flying in the same direction as the wind,
the wind helps it cover ground faster.

Plane + Wind = 460 mph

When the plane is flying opposite to the wind, the wind makes it
cover ground slower.

Plane - Wind = 400 mph

================================

OK.  So far we have

Plane + Wind = 460 mph
Plane - Wind = 400 mph

Add the two equations, and you get

2 Plane + zero = 860 mph

Divide each side by 2:  Plane = 430 mph

Plug that into the first equation:     430mph + Wind = 460 mph

Subtract 430 mph from each side:  Wind = 30 mph

If (12m,m) and (18m,6m) are two points on the graph of a line and m is not equal to zero what is the slope of a line?
tresset_1 [31]

Answer:

Option H. \frac{5}{6}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(12m,m)\ B(18m,6m)

Substitute the values

m=\frac{6m-m}{18m--12m}

m=\frac{5m}{6m}

Simplify

m=\frac{5}{6}

-9x = 5 - 2y. 15x = -11 + 2y <br>HELP ​
I am Lyosha [343]

Answer:

(-1, -2)

Step-by-step explanation:

-9x= 5 - 2y

15x = -11 + 2y => 2y = -11 - 15x

Plug the value for 2y into the first equation.

-9x = 5 - 15x - 11. Solve for x.

-9x = -6 - 15x.

-9x + 15x = -6.

6x = -6.

x = -1.

Now that we found x, we will solve for y.

2y = -11 - 15(-1)

2y = -11 + 15

2y = -4

y = -2.

Thus, our solution set is (-1, -2).

Hope this helps!

Solve 4x + 2 = 20 klkllk
Archy [21]

Answer:

x = 4.5

Step-by-step explanation:

First, we can subtract 2 from 20 (20 - 2) to get 18.

Now we know that x has to be multiplied by 4 and have a product of 18.

We can divide 18 by 4 to figure out what x is.

18 ÷ 4 = 4.5

We can check our answer by solving the equation:

4(4.5) + 2 = 20

18 + 2 = 20

20 = 20

(sorry if this is confusing but I hope it helped)
