Find the length of the third side to the nearest 10th

katovenus [111]

Answer:

9.5

Step-by-step explanation:

Using the pythagorean theorem a^2+b^2=c^2, we can say that 3^2+b^2=10^2.

Simplify and you get 9+b^2=100. Subtract 9 from both sides and you get b^2=91. When you take the square root you get 9.53939... round to the nearest tenth and the missing side is 9.5.

Y = –1/2x + 4

torisob [31]

Y = -1/2x + 4....sub in -1/2x + 4 in for y in the other equation

x + 2y = -8
x + 2(-1/2x + 4) = -8
x - x + 8 = -8
x - x = -8 -8
0 = -16...incorrect....NO SOLUTIONS
