saw5 [17]

Answer:

Bobby is correct

Step-by-step explanation:

Acute angles are classified as angles with a measurement of greater than 0° but less than 90°. If you add two acute angles, each as large as possible, the total will be less than 180 degrees.

Answer:

n = (-1000/3)p + (97000)/3)

Step-by-step explanation:

The data given says, in effect, that the linear equation based on price passes through 2 points (82, 5000) and (91, 2000), given two points on a line, we'll use the point-slope form to start.  To use this we must first find the slope

m = (y2 - y1) / (x2 - x1) = (2000 - 5000) / (91 - 82) = -3000 / 9 = -1000/3

(I like to leave slopes as fractions <rather than decimal> since fractions are more accurate)

point-slope form

y - y0 = m(x - x0) at some point (x0, y0) with slope m, we'll use (91, 2000)

y - 2000 = (-1000/3)(x - 91), distribute

y - 2000 = (-1000/3)x + 91000/3, add 2000 to each side

y = (-1000/3)x +97000/3

oops, substitute p for x and n for y

n = (-1000/3)p + (97000)/3)
