Answer:
x = 3 & y = 6
Step-by-step explanation:
4x = 12
12/4 = 3
x = 3
2y + 10 = 22
22 - 10 = 12
12/2 = 6
y = 6
Yes because your basically doing it the same way
Answer:
original price =54
change=68-54= 14
increse percentage= change/orginal x 100
=14/54 x100
=25.9%
Answer:
1.) 7th degree trinomial
2.) 5th degree binomial
Step-by-step explanation:
The degree of a term of a polynomial is the sum of the exponents of all the variables of that term. The degree of a polynomial is the same as the term with highest degree. Remember that a plain variable has degree 1. FOr example, 5x is a term of first degree because x is the same as x^1, so its degree is 1.
1.) m^5n^2 +mn^2 + n^6
Look at each term:
m^5n^2: degree = 5 + 2 = 7
mn^2: degree = 1 + 2 = 3
n^6: degree = 6
The highest degree of any term is 7, so the degree of the polynomial is 7.
The polynomial has 3 terms, so it's a trinomial.
Answer: 7th degree trinomial
2.) 12a^3b + 9a^2bc^2
Look at each term:
12a^3b: degree = 3 + 1 = 4
9a^2bc^2: degree = 2 + 1 + 2 = 5
The highest degree of any term is 5,so this is a 5th degree polynomial.
The polynomial has two terms, so it's a binomial.
Answer: 5th degree binomial
Answer:
0.000000049.
Step-by-step explanation:
This will have 7 zeros after the decimal point followed by 49:
4.9 × 10^–8 = 0.000000049.
If we imagine the decimal point making jumps to the right over the digits it takes 8 jumps till it gets to 4.9. that's where the -8 comes in.
