Answer:
5y3 without exponents would be 15.
the normal answer would be 15 y but they're no exponents.
A multiplication is zero if and only if at least one of the factors is zero. So, in this case, the multipications equals zero when
The first equation has no real solutions, because 
is a square, and thus it's positive. If you add 4 to a positive number, the result can't be zero.
The second equation has the solution
So, globally, the expression equals zero if and only if 
Answer:
x =2 x = -1
Step-by-step explanation:
|2x - 1| + 3 = 6.
Subtract 3 from each side
|2x - 1| + 3-3 = 6-3
|2x - 1|= 3
An absolute value has two solutions, one positive and one negative
2x-1 =3 2x -1 = -3
Add 1 to all sides
2x-1+1 =3+1 2x-1+1 = -3+1
2x = 4 2x =-2
Divide by 2
2x/2 = 4/2 2x/2 = -2/2
x =2 x = -1
Answer:
How much per a pencil and eraser? I'll help you out from there :)
Answer:
138,456
Step-by-step explanation:
Each year, the cost is multiplied by 1 +5% = 1.05. In 10 years, it will have been multiplied by that factor 10 times, so will be ...
85,000×1.05^10 ≈ 138,456
The cost of living in 10 years will be about 138,456 per year.
