Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(subtract like terms) (aka. 20c - 12c, 15r - 22r, 75p - 65p, 50e - 70e)
8c - 7r + 10p - 20e
Answer:
6+9=15
Step-by-step explanation:
Y = -2x + 5
That's the answer and you find it by finding the slope by using (4,-3) and (-2,9). You subtract -3 from 9 over 4 from -2. After you find the slope which would be -2 you use the equation y-y1 = slope(x - x1). You plug in any coordinates and find the answer.
