Answer:

I know it's hard right?

4y^{6}

Step-by-step explanation:

This is very simplistic, but this works(gets more complicated later)

Take the factors of both:

\frac{4*4*y*y*y*y*y*y*y*y}{4*y*y}

Next, cross out the common factors to get:

4*y*y*y*y*y*y

Simplifying, you get:

4y^{6}

Hope this helps!

Don't use it consistently, and instead assemble the factors in your head and cross them out, as this method takes a LOT of time compared to what I do know!

Solve the equation for all values of x.<br> (8x+9)(49x^2-100)=0
Liono4ka [1.6K]

Answer:

x = \frac{-9}{8} , \frac{-10}{7} , \frac{10}{7}

Step-by-step explanation:

8x+9=0

8x=-9

x = \frac{-9}{8}

or

49x^{2}-100 = 0

(7x)^{2} -10^{2} =0,

(7x+10)(7x-10)=0

7x+10=0, 7x-10=0

7x=-10, 7x=10

x=-\frac{-10}{7}, x = \frac{10}{7}

What is the domain for each function below? Choose the correct inequality symbol from the drop down menu and fill in the blank w
erik [133]

Answer:

x \le 3

x \ge 0

Step-by-step explanation:

The functions, missing from the question are:

f(x) = \sqrt{3 - x

f(x) = \sqrt{3 x

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

f(x) = \sqrt{3 - x

Equate 3 - x to 0

3 - x = 0

Solve for x

-x = -3

x = 3

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

x \le 3

(b)

f(x) = \sqrt{3x

Equate 3x to 0

3x = 0

Solve for x

x = 0

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

x \ge 0
