C. By three feet 7x5=35 area 7x10=70 area 7+3=10
(50,45)(125,37.50)
slope(m) = (37.50 - 45) / (125 - 50) = -7.5/75 = -0.1
y = mx + b
slope(m) = -0.1
(50,45)...x = 50 and y = 45
now we sub and find b, the y int
45 = -0.1(50) + b
45 = - 5 + b
45 + 5 = b
50 = b
so ur equation is : y = -0.1x + 50
so it the staff sells 150 yearbooks...
y = -0.1x + 50
y = -0.1(150) + 50
y = -15 + 50
y = 35 <== price per yearbook
Answer:
25 degrees
Step-by-step explanation:
![2x + 100 = 150 \\ 2x = 150 - 100 \\ 2x = 50 \\ x = \frac{50}{2} \\ x = 25](https://tex.z-dn.net/?f=2x%20%2B%20100%20%3D%20150%20%5C%5C%202x%20%3D%20150%20-%20100%20%5C%5C%202x%20%3D%2050%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B50%7D%7B2%7D%20%20%5C%5C%20x%20%3D%2025)
