8x + 34. What does X equal

rosijanka [135]

Answer: $x=-4.25$

Step-by-step explanation:

First you put it in to y= mx+b form.

$0=8x+34$

Then you subtract 34 from both sides

$-34=8x$

Then you divide 8 from both sides

Leaving you with

$x=-4.25$

4. Error Analysis Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her

Vinvika [58]

Answer:

She did not consider the multiplicative inverse property of a real number

Step-by-step explanation:

Jacinta in her conclusion did not consider the Multiplicative Inverse property of real numbers.

Let x be an irrational number.

So, $x.\frac{1}{x}= 1$

If x is an irrational number, then its reverse is also an irrational number. So by the Multiplicative Inverse property their product is 1 and 1 is a rational number. Thus, Jacinta was incorrect.

The radius of one sphere is twice as great as the radius of a second sphere. Find the ratio of their volumes.

Juliette [100K]

The ratio of the radii is 2:1, so the ratio of their surface areas is 4:1. The area of a sphere is defined by 4 * pi * r^2 

So if the radius of the first sphere is 2r, then it would be (2r)^2 = 4r^2 

The rest is the same. So the ratio of their surface areas would be 

4 * pi * 4r^2 divided by 
4 * pi * r^2 

or 4.
