What is the solution of sqrtx^2+49 = x+5?​
Lady_Fox [76]

Answer:

<h2>x = 12/5</h2>

Step-by-step explanation:

√x² + 49 = x + 5

Square both sides

(√x² + 49)² = ( x + 5)²

x² + 49 = x² + 10x + 25

Simplify

10x = 49 - 25

10x = 24

Divide both sides by 10

<h3>x = 12/5</h3>

Hope this helps you

PLS HELP <br><br> What is the correct graph for 3y-2x=6
VikaD [51]
Y = MX + B

You have to get Y by itself:

3y - 2x = 6

Add 2x to both sides
3y = 2x + 6

Now divide both sides by 3

Y = 2/3x + 2
----------------------------
So to find out which graph it represents

The Y interval (2) is where the line passes through on the Y axis

It seems like both lines pass through 2 (the first answer is not very clear)

So the slope is 2/3
For every "dot" or where a dot would be, you have to go up 2 and go right 3
----------------------------

it seems like the top one is the answer but I'm not sure, since its not clear. Hope this helps!

(Discrete Mathematics) If m and n are nonzero integers, show that (2m+3n)/5mn is a rational number.
Aloiza [94]

Answer:

\frac{(2m+3n)}{5mn}=\frac{2}{5n}+\frac{3}{5m} is a rational number for any m and n; nonzero integers.

Step-by-step explanation:

We have been given that 'm' and 'n' are nonzero integers. We are asked to show that \frac{(2m+3n)}{5mn} is a rational number.

We can rewrite our given number as:

\frac{2m}{5mn}+\frac{3n}{5mn}

Cancelling out common terms:

\frac{2}{5n}+\frac{3}{5m}

Since 'm' and 'n' are nonzero integers, so each part will be a rational number.

We know that sum of two rational numbers is always rational, therefore, our given number is a rational number.
