The formula is A= 1/2b x h
Area = half of the base multiplied by the height of the triangle

Express the equation x = 10 and y = -3 as a linear equation in two variables

34kurt

Answer:

For x = 10:

$x + 0y - 10 = 0$

For y = - 3:

$0x + y + 3 = 0$

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

$ax + bx = c$

So first let's solve for x=10:

$x = 10$

Move 10 to the other side.

$x - 10 = 0$

As there is no y given we will simply write 0y.

$x + 0y - 10= 0$

Now let's solve for y=-3:

$y = - 3$

Move -3 to the other side.

$y + 3 = 0$

As there is no x given we will simply write 0x.

$0x + y + 3 = 0$

which linear system has been correctly solved for one of the variables from the following system? 2x - y = -1 2x y = -7 2x - y =

mr Goodwill [35]

If you would like to solve the system of linear equations, you can do this using the following steps:

2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x

The correct result would be: y = 2x + 1, 2x + y = -7.
