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.
12) LCM of 2 & 12 is 12
Answer: (F)
13) (25 x 8) x 4
Step 1: Order of operations do parenthesis first: (25 x 8) = 200
Step 2: Multiply: 200 x 4 = 800
Answer: 800
14) I would plug each value in to see which works
D) 10x + 5y = 10(6) + 5(9) = 60 + 45 = 105
Answer is (D)
15) 2 x 12 - 8 (divided by) 2^2
Exponent first: 2 x 12 - 8 divided by 4
Multiplication/ Division: 2 x 12 = 24 and -8 divided by 4 = -2
Add/Subtract: 24 - 2 = 22
Answer: (I)
<span>2x-4y=32
2x-8y=48
--------------subtract
4y = - 16
y = -4
</span>2x-4y=32
2x- 4(-4)=32
2x + 16 = 32
2x = 16
x = 8
answer
(8, -4)
Answer:
75%
Step-by-step explanation:
or since a percent is a decimal then 0.75
So 1/4
that measn that the scale wall is 6 inches while the real wall is 4 times 6=24 inches tall (logically, it would be something like 1in/4ft so it woul dbe 24 feet not 24 inches but ok)
so 1/4
6 inches scale drawing is 1/4 of real wall
6=1/4 real
multiply by 4
24=real
asnwer is 24 inches
