Answer:
Step-by-step explanation:
I say seven...
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)
-b/2a would be 2/2 = 1 ... so find the y value at x = 1
12 - 2(1) - 15 = 1-17 = -16
So the vertex is at (1,-16)
Since the parabola opens upward from that point the minimum value of the range is y = -16
The range would include the point -16 so it is actually
R = [-16,infinity)

Step-by-step explanation:
Given
Two similar quadrilaterals
To determine
x, y, and z
Given that the two quadrilaterals are similar,
so their corresponding ratios will be:
x/10 = 5/4
x = 5/4 × 10
x = 50/4
x = 25/2
x = 12.5
Thus, the value of x = 12.5
To determine the value of y, the corresponding ratio such as
y/4 = 8/10
y = 8/10 × 4
y = 32/10
y = 16/5
y = 3.2
Thus, the value of y = 3.2
To determine the value of z, the corresponding ratio such as
z/5 = 15/x
as x = 12.5, so substitute x = 12.5
z/5 = 15/12.5
z = 15/12.5 × 5
z = 75/12.5
z = 6
Therefore, the value of z = 6
Conclusion:
