Y = (x + 4)(x - 2)
The x-intercepts:
0 = x + 4
0 = x - 2
x = -4
x = 2
The vertex:
y = (x + 4)(x - 2)
y = x^2 + 2x - 8
x = -b/2a
If ax^2 + bx + c, then:
a = 1
b = 2
c - 8
x -2/2(1)
x = -1
y = (-1)^2 + 2(-1) - 8
y = -9
The vertex is (-1, -9)
The x-intercepts are -4 and 2
Answer:
Marisa has made 6 sandwiches.
Step-by-step explanation:
The pounds of roast beef required to make each sandwiches is
, and not
as erroneously typed in the question.
Given that each deli sandwiches made, uses
pounds of roast beef.
Marisa started with 5 pounds, and had 2
pounds left.
Thus,
pounds of roast beef used = 5 - 2
= 5 - 
= 
= 
= 2
Marisa had used 2
pounds of roast beef. So that;
the number of del sandwiches made = 2
÷ 
=
÷ 
= 6
Therefore, the number of sandwiches made by Marisa is 6.
