Answer:
20a (less than or equal to) 28a
Step-by-step explanation:
PEMDAS
2a + 3= 5a
4*5a=20a
2. a+1=1a
-3*1a=-3a
-3a+31= 28a
Answer: y = -35x + 105
Step-by-step explanation:
The graph represents a function that is between hours and miles and to determine the equation which belong to this graph, we need to find the slope first by using two points from the graph which are (0, 105) and (3, 0).
The definition of slope is
m = (y2 - y1)/(x2 - x1)
= (0-105)/3-0
= -105/3
= -35
The slope is -35 and remember that the slope is the coefficient of the variable x. Therefore, the answer is:
y = -35x + 105
