Answer:
- x = 1
Step-by-step explanation:
<u>Given equation</u>
2^x = -2x + 4
To solve graphically, following steps required
1.<u> Graph the function</u>
- y = 2^x
2. <u>Graph the function</u>
- y = -2x + 4
3. <u>Identify any intersection of the lines</u>
4. <u>Take the x-coordinates of the intersection points and record as solution</u>
<em>See attached, the answer and the solution of the given equation</em>
<u>The solution is </u>
- x = 1
Answer:
see explanation
Step-by-step explanation:
The bar above the 3 indicates the 3 is being repeated, that is
0.13333....
We require to make 2 equations with the repeating 3 after the decimal point.
let x = 0.13333... , then multiply both sides by 10 then 100
10x = 1.3333 ← equation with repeating 3 after the decimal point
100x = 13.3333 ← second equation with repeated 3 after the decimal point
Subtracting the equations eliminates the repeated 3, that is
100x - 10x = 13.333 - 1.333
90x = 12 ( divide both sides by 90 )
x = ← divide numerator/denominator by 6, hence
0.1333... =
