Each numbers (except 0) to zero power are equal 1. So $(-5a^5b^4c^3)^0=1$ assuming $abc \neq 0$

What is the difference between the fractions? Use the number line to help find the answer.

NNADVOKAT [17]

Answer:

The difference is $\frac{3}{10}$

Step-by-step explanation:

We must find the common denominator of the fractions.

The common denominator of $\frac{1}{2}$ and $\frac{1}{5}$ is $2*5=10$ ; therefore we have

$\frac{1}{2}=\frac{5}{10}$

$\frac{1}{5} =\frac{2}{10}$

now it is easy to subtract $\frac{5}{10} -\frac{2}{10}$ using the number line: we have to move $\frac{3}{10}$ units to the left in order to get to $\frac{2}{10}$ .

Thus our answer is

$\boxed{\frac{1}{2} -\frac{1}{5}=\frac{3}{10} }$

Simplify completely 10x6y3+20x3y2/5x3y

Kryger [21]

Answer:

$\large\boxed{\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=2x^3y^2+4y}$

Step-by-step explanation:

$\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=\dfrac{(5x^3y)(2x^3y^2)+(5x^3y)(4y)}{5x^3y}\\\\=\dfrac{5x^3y(2x^3y^2+4y)}{5x^3y}\qquad\text{cancel}\ 5x^3y\\\\=2x^3y^2+4y$

What is the rule for Aaliyah’s machine? Try to write the rule as an equation.

Eva8 [605]

Answer:

f(x) = 2x +1

Step-by-step explanation:

Apparently the ordered pairs are ...

(x, f(x)) = (1, 3), (2, 5), (3, 7), (4, 9)

We note that as x increases by 1, the value of f(x) increases by 2. The difference between f(x) and 2x is 3-2·1 = 1, so we have ...

f(x) -2x = 1

f(x) = 2x +1 . . . . . . add 2x
