Answer:
x=0.5×1±√33
Step-by-step explanation:
x+8=x² and 2(x+8)=2x²
x²-x-8=0
Answer:
It will be at 33.3333 repeating so if you estimate the answer is y = 33
Step-by-step explanation:
The change in the X values is in multiples of 2.
The change in the h(x) values need to be: -0.3 x 2 = -0.6
Now find the h(x) values that have a difference of -0.6
A negative value is a decrease.
2 to 4 is an increase.
4 to 6 is an increase.
6 to 8 is an increase.
8 to 10 is an increase.
10 to 12 = 20-19.8 = 0.2
12 to 14 = 19.8 - 19.2 = 0.6
The two columns are 12 and 14
Answer:
1. -2+2x=y
Step-by-step explanation:
You only need to try the first two lines of the table to determine which equation works.
Only equations 1 and 4 work for the first line of the table (x=0).
- 1. -2 +2·0 = -2 . . . . . . . this works
- 2. 2 -2·0 = 2 ≠ -2
- 3. 2 +2·0 = 2 ≠ -2
- 4. -2 +0 = -2 . . . . . . . this works
Of those, only equation 1 works for the second line of the table (x=1).
- 1. -2 +2·1 = 0 . . . . . . . this works
- 4. -2 +1 = -1 ≠ 0
The equation that is true for the table values is ...
-2 +2x = y
