Answer:
x=3
Step-by-step explanation:
axis of symmetry always pass through X coordinate of vertex.
here vertex is (h,k)= (3,5)
so x coordinate is 3.
so the equation of the axis of the symmetry is X=3
The value is 22 because I took the test
Since it is perpendicular to y=3x-1, the slope must be a negative reciprocal.
there the slope of the perpendicular line is

So now we have,

To find b, we use the point that the line passes through and substitute it to the y and x values.

which would give us b=5/3
Therefore, the equation of the line is
6 is 75% of 8. 6/8 can be simplified to 3/4, which is easier to see as 75%.
See this solution/explanation (answer is '7 meters'):
1. According to the condition 'y' means the height, and 'x' - the length from the start of the lift hill.
2. The phrase 'height of 343 meters' means y=343.
3. From the another side y=x³. If to substitute 343 instead of 'y': 343=x³, - it is possible to find the value of 'x'.
x=<u>7 [m]</u> - how far from the start of the lift hill...
