Find the length of the unknown side. round your answer to the nearest tenth. 14.0 13.0 12.5 11.5

The correct option is:  11.5

Step-by-step explanation:

Suppose, the length of the unknown side is  

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and .

So, the length of the unknown side is 11.5

The correct option is:  11.5

Step-by-step explanation:

Suppose, the length of the unknown side is  

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and .

As the given triangle is right angle triangle, so using Pythagorean theorem, we will get.........

(Rounded to the nearest tenth)

So, the length of the unknown side is 11.5

where's the diagrams?

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
