Answer:
See attached picture.
Step-by-step explanation:
To graph the line, start at (0,-3) since b = -3 in the equation. This is the y-intercept. Mark this point. From this point, move down 2 units and to the right 1 unit. Mark this new point at (1,-1). Connect the points with a line. See attached picture.
The equation for surface area of a sphere is SA=4*pi*r^2
We can plug in what we know to solve for r
400=4*pi*r^2
100=pi*r^2 (divide out the 4)
100/pi=r^2 (divide out the pi)
√(100/pi)=r (square root of both sides)
r=5.6 rounded to the nearest tenth
Answer:
x = 26/15
Step-by-step explanation:
is means equals
52 / x = 30
Multiply each side by x
52 = 30x
Divide each side by 30
52/30 = x
26/15 = x
