just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
Percent equal to 31.43 percent.
Its multiplication so you divide both sides by 3.25 and that leaves u with N=100 because 325.00 divide by 3.25 is 100
Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.
Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2 Which means triangle is obtuse triangle.
Answer: Obtuse Triangle
