Solve for y please I have no clue I am so lost thank you
Inga [223]

In the Triangle ABD, Using Pythagoras theorem we can write

AB^2=BD^2+AD^2\\ \\ AB^2=9^2+y^2\\ \\ AB^2=81+y^2\\ \\

In the Triangle ACD using Pythagoras Theorem

AC^2=AD^2+CD^2\\ \\ AC^2=y^2+7^2\\ \\ AC^2=y^2+49\\

Now in the larger Triangle ABC, we can write

AB^2+AC^2=BC^2

Now substitute the values from the above equations we get

81+y^2+49+y^2=(9+7)^2\\ \\ 130+2y^2=16^2\\ \\ 130+2y^2=256\\ \\ 65+y^2=128\\ \\ y^2=128-65=63\\ \\ y=\sqrt{63} =3\sqrt{7} \\

If the value of x increases by 1, what happens to the value of y? y=8x+2
Nikitich [7]

Answer:

y will increase by 8

Step-by-step explanation:

y = 8x+2

We increase x by 1

Replace x with x+1

y = 8(x+1) +2

y = 8x+8+2

y = 8x+2   +8

y will increase by 8
