X + 19 + 7x + 9 = 180
8x + 28 = 180
8x = 180 - 28
8x = 152
X = 152 : 8
X = 19
I would say Tuesday, since it’s the only part that decreases on the whole graph.
Answer:
(-3,0)
Step-by-step explanation:
the vertex is where the quadratic function reaches its maximum or minimum height and as you can see on this graph the maximum height of this equation is at the (-3,0) point meaning that (-3,0) is the vertex
12x+7+6x-7=90
12x+6x=90
18x=90
x=5
6(5)-7=
30-7=23
Q=23
Change in y over change in x is key
(4-1)/(5-6)=3/-1
13. -3
(9-4)/(2-0)=5/2
14. 5/2
(1-(-2))/(-6-4)=3/-10
15. -3/10
