2^2x+2 *5^x-1=8^x*5^2x

Liula [17]

Answer:

The solution will be "x = 2 and x = -1".

Step-by-step explanation:

The given equation is:

⇒ $2^{2x+2}\times 5^{x-1}=8^x\times 5^{2x}$

On solving " $8^x$ ", we get

⇒ $2^{2x+2}\times 5^{x-1}=(2^3)^x\times 5^{2x}$

As we know, if the base are same then their powers will be added together.

⇒ $2x+2=3x$ ...(equation 1)

⇒ $x-1=2x$ ...(equation 2)

From equation 1, we get

⇒ $2=3x-2x$

⇒ $2=x \ i.e., x =2$

From equation 2, we get

⇒ $-1=2x-x$

⇒ $-1=x \ i.e., x=-1$

So that the correct answer will be "x = 2" and "x = -1".

Can someone please help me with this statistics question?

stiks02 [169]

Probability of an event happening is given by:
probability of an event happening=number of ways it can happen/total number of outcomes
number of random selection=40
total number of patients who did not leave against medical advice=52,560
thus the probability that at random selection none of the 40 patients left the treatment center against medical advice will be:
40/52560
=0.00076

What is the inequality -3x + 1 < 7 look like on a number line.

grandymaker [24]

Step-by-step explanation:

First you must simplify the equation:

$-3x+1$

subtract 1 from both sides:

$-3x$

than divide both sides by -3, which switches the inequality sign:

$x>-2$

This inequality means that all values of x greater than -2 work for the equation. because it is not $\geq$ , -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.
