Answer:

x = 4

Step-by-step explanation:

4x + y = 10

They are telling you that y = - 6 so you put that into the equation and solve for x.

4x + (- 6 ) = 10   or 4x - 6 = 10

Add 6 to both sides

4x - 6 + 6 = 10 + 6

4x = 16

Divide both sides by 4

4x / 4 = 16 / 4

x = 4

You can check your answer by put you x value into the same equation and solve for y.  It should equal - 6.

4(4) + y = 10

16 + y = 10

y = - 6

Graph the solution to the following linear inequality in the coordinate plane 5x-y>-3
Irina18 [472]

Answer:

Here's one way to do it

Step-by-step explanation:

1. Solve the inequality for y

5x - y > -3

      -y > -5x  -  3

       y < 5x + 3

2. Plot a few points for the "y =" line

I chose

\begin{array}{rr}\mathbf{x} & \mathbf{y} \\-2 & -7 \\-1 & -2 \\0 & 3 \\1 & 8 \\2 & 13 \\\end{array}

You should get a graph like Fig 1.

3. Draw a straight line through the points

Make it a dashed line because the inequality is "<",  to show that points on the line do not satisfy the inequality.

See Fig. 2.

4. Test a point to see if it satisfies the inequality

I like to use the origin,(0,0), for easy calculating.

y < 5x + 3

0 < 0 + 3

0 < 3. TRUE.

The condition is TRUE.

Shade the side of the line that contains the point (the bottom side).

And you're done (See Fig. 3).

You have the side opposite the angle and the Hypotenuse so use soh

Sine(x) = opposite/Hypotenuse

Sine(x) = 9/19

X = sin-1(9/19) - - - - - here the - 1 is to the power of
