Answer:
-2
Step-by-step explanation:

the line is going down meaning its a negative and to find the slope do rise over run
Step-by-step explanation:
x+3=8
8-5=3 so x=5
7+5=12 / 12-7=5
12-5=7
You start with the basic y=x^2.
That’s the parabola with a vertex at (0,0), opening up, etc.
The transformation aspect is the “+7” portion. This “+7” shifts the entire graph of y=x^2 up by 7 units.
The vertex is now (0,7), it still opens up, etc.
It’s kind of a silly question for your teacher to ask when the graph given only goes up to 6.
Answer:
radius = 7 units
Step-by-step explanation:
Given:
Radius = 7 units
Find area of 4 circles:
1 circle = π (7)² = 49π units²
4 circles = 49π x 4 = 196π units²
Find radius of sphere:
4πr² = 196π
r² = 49
r = 7
