So you first need to make both equivalent fractions. You do that by making the denominator the same so you need to find a common multiple between both which is 12 so you multiply 2/3 by 4 on the top and bottom to get something equivalent to 7/12. 7/12 +8/12=15/12 now you divide 15 and 12 to have it in fraction mode you’ll be getting that Judy and her sister studied for 1 hour and 25 minutes

Answer: $g(x)=\frac{1}{2}f(x)$

Step-by-step explanation:

We see that g(x) is a straight line that passes through the origin, just like f(x), so g(x)=kx for some constant k.

Since g(x) passes through (4,2), we know that 2=4k, and thus k=1/2.

So, $\boxed{g(x)=\frac{1}{2}f(x)}$

Which of the following expressions are equivalent to 2/x^6-y^6? Choose all that apply.

enot [183]

Answer:

A and C

Step-by-step explanation:

Equivalent expressions are expression which when simplified to lowest terms are equal.

Simplify each answer choice to find the expression which simplifies to $\frac{2}{x^6-y^6}$ .

A. Multiply the exponents 3*2 = 6. This is equal.

B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.

C. Here the numerator does equal 2. The denominator multiplies to $(x^3 - y^3)(x^3+y^3)\\x^6 -x^3y^3 + x^3y^3 -y^6\\x^6 - y^6$

This is equal.

D. The denominator will have three terms here when simplified. This will not be equal.

What are the steps to simplify 1-2/x-2=x+1/x+2?<br>Plz help ASAP!!!

vichka [17]

Answer:

$-x^3+x^2+x-6=0$

Step-by-step explanation:

Algebra

The equation is shown without proper format, we'll assume the correct equation is like

$\displaystyle 1-\frac{2}{x-2}=x+\frac{1}{x+2}$

Multiplying all the equation by (x-2)(x+2)

$(x-2)(x+2)-2(x+2)=x(x-2)(x+2)+(x-2)$

Operating

$x^2-4-2x-4=x^3-4x+x-2$

Rearranging and simplifying

$\boxed{-x^3+x^2+x-6=0}$
