If 3(y-1) = y -5. y = ____________.

Mathematics

Answer:

-1 is the answer

Step-by-step explanation:

the question is 3(y-1)=y-5

so, we open the bracets and multiply

so it becomes 3y-3 = y-5

now, we transpose

3y-y =-5+3

2y = -2

y= -2/2 = -1

Answer:

y = -1

Step-by-step explanation:

3(y-1)=y-5\\\\3y-3=y-5\\\\3y-3+3=y-5+3\\\\3y=y-2\\\\3y-y=y-y-2\\\\2y=-2\\\\\frac{2y=-2}{2}\\\\\boxed{y=-1}

Hope this helps.

On a cube, what proportion of the surface area is on each face, to the nearest percent?
Nookie1986 [14]
Cubes have 6 equal faces, and the surface area is the sum of all of these faces. Thus, one face would be 1/6 of the cube's surface area, or about 17%.

Question 5: prove that it’s =0
mamaluj [8]

Answer:

Proof in explanation.

Step-by-step explanation:

I'm going to attempt this by squeeze theorem.

We know that \cos(\frac{2}{x}) is a variable number between -1 and 1 (inclusive).

This means that -1 \le \cos(\frac{2}{x}) \le 1.

x^4 \ge 0 for all value x. So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.

-x^4 \le x^4 \cos(\frac{2}{x}) \le x^4

By squeeze theorem, if  -x^4 \le x^4 \cos(\frac{2}{x}) \le x^4

and \lim_{x \rightarrow 0}-x^4=\lim_{x \rightarrow 0}x^4=L, then we can also conclude that \im_{x \rightarrow} x^4\cos(\frac{2}{x})=L.

So we can actually evaluate the "if" limits pretty easily since both are continuous  and exist at x=0.

\lim_{x \rightarrow 0}x^4=0^4=0

\lim_{x \rightarrow 0}-x^4=-0^4=-0=0.

We can finally conclude that \lim_{\rightarrow 0}x^4\cos(\frac{2}{x})=0 by squeeze theorem.

Some people call this sandwich theorem.

Is 70 thousand written in standard form or word form explain
sladkih [1.3K]
It is actually written as a mixture of the two. The standard form would be 70,000, while the word form would be writing seventy thousand. Both are equally valid but the mixture found here is avoided in literary writing. Standard form is just a weird way of saying numeral form or Arabic numerals form or anything similar.
