Answer:
y = -1/5x + 6.4
Step-by-step explanation:
Use the point-slope formula.
y-y₁ = m(x -x₁)
so...
y-7 = -1/5(x - (-3))
y = -1/5x+ 32/5
and you need you can change 32/5 to 6.4
Hope this helps!
Answer:
The first one
Step-by-step explanation:
The order of operations is PEMDAS. You would work on multiplying the -6 and 3.
Answer:
V =65416.666666 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The diameter is 50 so the radius is 1/2 of the diameter
r = 1/2 (50) = 25
V = 4/3 ( pi) (25)^3
V = 4/3 (pi) 15625
V =20833.3333 pi
Using 3.14 for pi
V =65416.666666 cm^3
