Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50
x = 2
Ann: 21
Jim: 31
Miguel: 63
Let’s start by finding Ann’s number.
a + (a + 10) + 3a = 115
5a + 10 = 115
5a = 115 - 10
5a = 105
a = 105 / 5
a = 21
Now, just find the others’ numbers using Ann’s.
Jim sent ten more messages than Ann, and 21 + 10 = 31.
Miguel sent 3 times as many messages as Ann, and 21 * 3 = 63.

Step-by-step explanation:
Answer:
The graph of the function
has a minimum located at (4,-3)
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex of the parabola
If a > 0 the parabola open upward and the vertex is a minimum
If a < 0 the parabola open downward and the vertex is a maximum
In this problem
The coefficient a must be positive, because we need to find a minimum
therefore
Check the option C and the option D
Option C
we have

Convert to vertex form

Factor the leading coefficient





The vertex is the point (4,-3) ( is a minimum)
therefore
The graph of the function
has a minimum located at (4,-3)
