Answer:
F(x)=(x-3)(x+8)(x-11)=0
(x-3)=0, (x+8)=0, (x-11)=0
X=3
X=-8
X=11
Answer:
Top and Bottom angle: Obtuse
Right and Left angle: Acute
There are 2 acute angles, 0 right angles, and 2 obtuse angles in this figure.
It is an irrational number.
As a decimal, it equals 1.414235... This is a nonrepeating and nonterminating decimal, which makes it an irrational number, It also cannot be represented as a ratio of two integers.
The change in x between the two is 3 and the change in y is -9.
Divide -9 by 3 to get -3 using the rise over run slope formula.
The equation is y = -8 + -3x because the -8 in the second set of coordinates is the y-intercept of the equation.
Hope this helps!
67.50 + 12.50 = 80
80/100 = 0,8 x 3 = 2.4
so, the total bill was 80 + 2.4 = 82.4
