Answer:
no solution
Step-by-step explanation:
3(x+5) +2x=10x-5(x+1)
Distribute
3x+15 +2x = 10x-5x-5
Combine like terms
5x+15 = 5x -5
Subtract 5x from each side
5x-5x+15 = 5x-5x-5
15 = -5
This is never true so there is no solution
(E)
Step-by-step explanation:
Note that the point at x = 1 has an open circle which that it's not part of the domain. Speaking of which, the domain only covers between -2 and 1 (but not including 1). The graph has a positive slope and when x = 0, y = 1 which the equation and domain in (E) satisfy.
Answer:
4*10^18
Step-by-step explanation:
Easier to think of it as the factors out front (8 / 2) = 4
and subtract the exponents 30 - 12 = 18
= 4*10 ^18
