How to simplify -6k +7k 12r -8 -12 n -10 +9n -3 -4x-10x -r -10r

Mathematics

Semmy [17]3 years ago

Answer:

Solve by adding or subtracting like terms. (Ex. 2k + 4k = 6k; 9 + 7 = 16)

- 6k + 7k = 1k = k

(7 - 6 = 1)

12r - 8 - 12 = 12r - 20

(8 + 12 = 20 but sign is negative) 12r will stay the same because there are no terms with a letter r.

n - 10 + 9n - 3 = 9n + n - 10 - 3 = 10n - 10 - 3 = 10n - 13

(n = 1 so 9 + 1 = 10; 10 + 3 = 13 but negative sign)

- 4x - 10x = 14x

(10 + 4 = 14)

- r - 10r = 11r

(r = 1 so 10 + 1 = 11)

The answer would be 65.9%. Add both paper numbers together (26.5+51.3) which is to 77.8.. to find paper not recycled just put 51.3/77.8 which would be 0.659 as a decimal.. move the decimal over to the right twice and that'd be your percentage.

In the equation f(x) = (3x + 5) (x2 - 6x + 9)2 = 0, 3 has a multiplicity of ______.
Svetradugi [14.3K]
Multiplicity is how many times the root (or zero) is repeated

example, in f(x)=a(x-b)^n(x-d)^m... the root b has a multiplicity of n and the root d has a multiplicity of m

first we need to get the roots into f(x)=a(x-b)^n(x-d)^m
for (3x+5), we need to force factor out the 3 to get
3(x+\frac{5/3})

factor the other one
(x^2-6x+9)=(x-3)(x-3)=(x-3)^2
but it is (x^2-6x+9)^2 which is equivilent to ((x-3)^2)^2 which simplifies to (x-3)^4

so we get
f(x)=3(x+\frac{5}{3})(x-3)^4
so the roots are -5/3 multiplicity 1 and 3 multiplicity 4


3 has a multilicity of 4
