A + B
Klio2033 [76]

Answer:

A= 0.5 and B= 4040

Step-by-step explanation:

If you write out the equation and rearrange a little it gets easier to understand.

( a + b) + (a*b) + (a - b)  you can rewrite this as

a + b + a - b + (a*b)  this is the same as 2a + ab = 2021

The way I looked at it is to figure out how to get that number 1 at the end.

The number 2020 is easy to get to.  How can you get the number 1 using either 2a or ab.

I looked at a = 0.5.   2 times 0.5 would be 1.

So now what would b have to be?  We can get the 1 at the end with the 2a part of the equation so now we have to get ab = 2020.

b = 2020/a  which using our a = 0.5, you can see that b would have to equal 4040.  Test it all out in your equation.

0.5 + 4040 + (0.5 * 4040) + 0.5 - 4040

4040.5 + (2020) - 4039.5 = 2021

So A = 0.5  and B = 4040

Compare how you would model And récord finding the sum And difference of two rocks weighing 2/8 pound And 3/8 pound .
-Dominant- [34]
To find the sum and difference of the two rocks, you would do:

\frac{3}{8} + \frac{2}{8} =  \frac{3+2}{8} =\boxed{\bf{\frac{5}{8}}}\\\\\\ \frac{3}{8} - \frac{2}{8} =  \frac{3-2}{8} =\boxed{\bf{\frac{1}{8}}}

Geometry page 1 help please !
victus00 [196]

Answer:

16) y=\frac{1}{4}x +5

17) y = -x - 4

18) y = -2x - 1

19) y = -2x

20)y=\frac{-5}{3} -3

Step-by-step explanation:

With the two points you find the slope using \frac{y_{2}-y_{1}  }{x_{2}-x_{1} }

Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
