1 answer:

4 0

√72 can be written as 3√8 , √128 as 4√8.. Here, we have to solve √72 -√8 +√128 .. i.e, 3√8 - √8 + 4√8.. which is equal to 6√8 or can be written as 12√2 //

2. What is the slope of the graph of 4x + 5y = 10?

Temka [501]

Answer:

-0.8 or -4/5

Step-by-step explanation:

You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:

4x + 5y = 10

5y = -4x + 10

y = -4/5x + 2

So your slope is -4/5.

Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.
