Answer:
(D)On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Step-by-step explanation:
For a parabola 
to have a minimum vertex, it must open upward. (a>0).
In the given options, the parabola which opens upward is option D.
On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Therefore, it has a minimum vertex with coordinates (0,-4).
The slope of a horizontal line =0 not undefined the slope of a vertical line= undefined
Answer:
174.25
Step-by-step explanation:
To solve this equation I will assume you are 15 as this is a High School level problem.
1. Plug in 15 for x
-.85*15+187
2. Solve
-.85*15=-12.75
-12.75+187=174.25
To make a LINE that is 12 cm long, you'd need (12 / .75) cubes or sixteen cubes.
To make a CUBE you'd need 16^3 cubes or 16*16*16 cubes or 4,096 three quarter centimeter cubes.
It will take her 45 minutes to run 5 miles,because 27/3=9 and 9•5=45
