Answer:
7) a = 60; b = 100
8) c = 20
9) d = 45
Step-by-step explanation:
7)
a + 120 = 180
a = 60
b + 80 = 180
b = 100
8)
5c + 4c = 180
9c = 180
c = 20
9)
3d + d = 180
4d = 180
d = 45
If you times 39.99 by 0.20 (20%) then you get your answer of $7.99
To solve:
Simplify 128x^5/8x first
16x^4
then divide by 1/4
16x^4•4/1=64x^4
Answer: 64x^4
Answer:
B) Yes, because the slope is
and the zero is (12, 0)
Step-by-step explanation:
From inspection of the graph:
- y-intercept = (0, 100)
- Two points: (3, 75) and (6, 50)

Therefore, the equation of the line in slope-intercept form y = mx + b
(where m is the slope and b is the y-intercept) is:

To find the zero (when y = 0), set the equation to zero and solve for x:




Therefore, the zero is at (12, 0)
Therefore, the graph does represent the function because the slope is
and the zero is at (12, 0)
X would be -5
Hope this helps :)
