Answer:
x = 14 and x = - 7
Step-by-step explanation:
Not that + (- ) = -
(a)
x + (- 4) = 10, that is
x - 4 = 10 ( add 4 to both sides )
x = 14
(b)
2x - 10 = - 24 ( add 10 to both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7
Answer:
dy/dx = 9x²+2
dy = (9x²+2) dx
dy/dt = (9x²+2) dx/dt
if x = 2 and dx/dt=5 then
dy/dt = (9*2²+2)*5 = 38*5 = 190
68.82-5.32(sales tax)-3.00=60.5
60.5 divided by 2= 30.25
