Answer:
The answer is B
Step-by-step explanation:
plug 2 into x to see
A.
x^2 + 8
2^2 + 8
4 + 8 = 12
B.
3x^2 + 1
3(2)^2 + 1
3(4) + 1
12 + 1 = 13
C.
2x^3 + 5
2(2)^3 + 5
2(8) + 5
16 + 5 = 21
D.
x^2 + x
2^2 + 2
4 + 2 = 6
0 or if maybe another 0 for two ZER0s
Step-by-step explanation:
step 1. when you graph 2 lines they must intersect unless they are parallel (same slope)
step 2. if they intersect then they have one point in common
step 3. that point in common solves both equations
step 4. when a point solves both equations it is called the solution.
24. 8x3=24
12x2=24
It would be 6/24 (3/12) and 9/24 (3/8)
With these, always write out the multiples first.
Start like this:
(assume one of the factors is negative)
1 and 1120
2 and 560
4 and 280
5 and 224
7 and 160
8 and 140
10 and 112
14 and 80
16 and 70
20 and 56
28 and 40
32 and 35
from those, the obvious choice is the one with a difference of three. In this case, 32 and 35, because -32 + 35 equals 3.
