When determining intercepts algebraically and you get an imaginary solution, this would mean that the graph of the function does not pass through the x or the y axis. X-intercept is the value of x when y would be equal is zero or the value x when the graph passes/ intersects the x-axis. On the other hand, the y-intercept is the value of y when x is zero or the value of y when the plot intersects the y-axis. Therefore, the value of these intercepts should be real values and not imaginary numbers or else these intercepts do not exist. The plot of the equation would not cross any of the axes in the coordinate.
Answer: 0.5 < x < 16.5.
Step-by-step explanation:
Given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
- Sum of any two sides > third side. (i)
- Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
Answer: n = 160
Step-by-step explanation: Solve for n by simplifying both sides of the equation, then isolate the variable.
Hope this helps you out! ☺

Answer:
A regression coefficient is the same thing as the slope of the line of the regression equation.
Step-by-step explanation:
The equation for the regression coefficient that you'll find on the AP Statistics test is: B1 = b1 = Σ [ (xi – x)(yi – y) ] / Σ [ (xi – x)2].
