1. A. y and 1.2y are like terms. c they both contain the same term (y) and can therefore be combined.
2. B. 12x+11 (you have to combine the like terms)
3. 15y+18-4
C. 15y+14 (you must distribute the 3 to inside the parentheses, so 3×5y and 3×6)
4. 9(9-3p) (you have to find a common factor between the terms, in this case 9, and you place it on the outside of the parentheses, while dividing that factor from those terms, which are placed in parentheses.
This is just like an exponential growth equation...
Final=initial*rate^periods
25000=12500(1.0525)^t
2=1.0525^t
ln2=t ln1.0525
t=ln2/ln1.0525
t=13.55
t=14 yrs
Answer:
m = 6
Step-by-step explanation:
Here, we want to find the value of m
To do this, we use the indices addition property for multiplication
On the left hand side;
5^(2 + m + 7) = 5^15
5^(m + 9) = 5^15
since the bases are equal, we equate the powers
m + 9 = 15
m = 15-9
m = 6
Answer:
2^3 or 8
Step-by-step explanation:
when you divide an exponent by an exponent, you subtract the 2 exponents
For example, 2^6/2^3=2^(6-3)=2^3
If you want to simplify 2^3, it is equal to 8
