Answer:
A. Quartic
Step-by-step explanation:
I went to desmos graphing,
8x^2+1/9 (plug it in and looked at the line)
It shows a parabola,
y-intercept: (0,0.111)
"Cubic functions. Three points not in a line determine a parabola, a polynomial function of degree 2. Polynomials of degree 2 are quadratic functions. Their graphs are parabolas."
Therefore, this is a quadratic ( quartic) since the degree in this parabola is 2.
<span>a = 1/2 x b x h
h = 3b
so 1/2 x b x 3b = (1/2)(3b^2) = 150
(150 x 2)/3 = b^2
100 = b^2
b = square root of 100 = 10
h = 3b = 3 x 10 = 30</span>
The answer is -7
2x-3(x+4)=-5
Multiply by -3
2x-3x-12=-5
Collect like terms
-x-12=-5
Move constant to the right to change its sign
-x=-5+12
Add
-x=7
Change the signs
x=-7
Answer:
15$
Step-by-step explanation:
35-10=25$
25-5=20$
