The straight line is perpendicular to y = -3x + 4.
Therefore, the gradient of the straight line must be 3.
The equation of the straight line is y = 3x + 2.
Simplify
f(x) = 3 + 11
Multiple
fx = 3x + 11
<span>Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 11x-1 + 3
Simplifying
f = 11x-1 + 3
Reorder the terms:
f = 3 + 11x<span>-1</span></span>
Answer: D) x>2.
This is because the slope of the exponential function is clearly greater than the linear function from 2 on the x=axis forward.
Where is the scale image?
You just have to multiply $8.50 by 1.065.
So, the answer is 9.0525 or about $9.05
