Answer:
P = -0.004Q + 149
Step-by-step explanation:
The general form of the linear equation is:
The slope of the equation (a) can be found by using the two given points (4,000; $133) and (27,000; $41)
Applying the point (4,000; $133) to the equation below yields in the linear equation for Price as a function of the number of shirts:
The linear equation is:
P = -0.004Q + 149

... 11.4 = what number . . . . . . . . carry out the multiplication
_____
If you're asked to write this as a proportion, you can write it like this:
You can solve this proportion by multiplying by 57 (the denominator under "what number"). Doing so gives you the same arithmetic sentence as shown above.
Answer:
Step-by-step explanation:
The reference angle is the angle that the given angle makes with the x-axis.
For an ordered pair to share the same reference angle, the x and y coordinates must be the same or a factor of each other.
From the given options:
We observe that only the pair in option C has the same x and y coordinate with the second set of points being a negative factor of the first term. Therefore, they have the same reference angle.
