Answer:
true
Step-by-step explanation:
Using the order of operations to evaluate the expressions, we have ...
8 + 5(8) ≥ 9(5)
8 +40 ≥ 45
48 ≥ 45 . . . . . true
80% of quizzes + 20% of final = final grade
80% * 73 + 20% * x = 70
0.8 * 73 + 0.2x = 70
58.4 + 0.2x = 70
0.2x = 11.6
x = 58
Answer:
y = -0.25x - 6
Step-by-step explanation:
You can either just read off the slope m = -0.25 and the intersection with the vertical n = -6 or you form a system of equations from points you choose on the graph. For example:
(0,-6);(4,-7)
The general equation for a line:
y = m*x + n
The two points on the graph form a system of two equations:
1. -6 = m*0 + n
2. -7 = m*4 + n
You can read off n right away fro equation 1:
n = -6
Plugging n into equation 2:
-7 = m*4 - 6 => -1 = m*4 => m = -1/4
Answer: 
Step-by-step explanation:
Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
Therefore, the slope is .
