Consider this system of two linear equations.

katen-ka-za [31]

Answer:

Step-by-step explanation:

so these two lines cross at some point.. and they want to know the y point at which they cross... sooo..

solve them as a system to find the points that are common to both

Eq. 1) 5x -2y = 16

Eq. 2) -4x+6y=-15

i'll use the elimination method as these equations "lend" themselves to that way.. they are easy to solve that way .. in other words..

multiply Eq. 1 by 3 the add Eq. 2 .. to it... add the terms as columns....

15x-6y = 48

= 11x+ 0y =33

x=3

nice, now plug 3 in for x in one of the Eq. try Eq. 1

5(3)-2y=16

15-2y=16

-2y =1

y = $-\frac{1}{2}$

since we're looking for the y coordinate... that's your answer $-\frac{1}{2}$

Answer:

x = $\frac{\sqrt{22} }{2}$

Step-by-step explanation:

Using the Pythagorean Theorem we can solve this problem.

The legs of the triangle will be the same (the dashes in the middle of the line indicates they are the same).

The Pythagorean Theorem will look like this:

$a^{2}+a^{2} = (\sqrt {11})^{2}$

Now, let's find a:

$2a^{2} = 11$ The square of a radical will be whatever is under the arch

$a^{2}=\frac{11}{2}$ Divide 11 by 2

$\sqrt{a^{2} } = \sqrt{\frac{11}{2} }$ Square root both sides

a = $\frac{\sqrt{22} }{2}$

Therefore, the length of side x is equal to $\frac{\sqrt{22} }{2}$ .

Hope this helps!!
