The table shows the wavelength of the sound produced by keys on a piano x keys away from the a above middle c.
using the exponential regression model, which is the best prediction of the wavelength of the key that is 8 above the a above middle c?

49.3149.4449.7349.78

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
