You have to derive for a multiplication in both terms:
=e^x+xe^x-(e^x-1 + (x-2)e^x-1) now apply distributive property in the last term:
=e^x+xe^x+e^x-1-xe^x-1   now replace each x by 0 (x=0)
=1 + 0 + e^-1 + 0 = 1+ e^-1 = 1.3679

Give the values of a, b, and c needed to write the equation's standard form. 1/4x^2+5=0
Pavel [41]
The equation in its standard form is written as followsax ^ 2 + bx + c = 0
 To find the values of a, b, c we must compare the given equation with the standard equation. Comparing we have:
 ax ^ 2 + bx + c = 0
 1 / 4x ^ 2 + 5 = 0
 Therefore the values of a, b, c are
 a = 1/4
 b = 0
 c = 5

12 more than the difference of<br> half a number and 3 is 45.<br> Plz answer
son4ous [18]

Answer:

x=18

Step-by-step explanation:

the result of 12 added to the difference of half a number and 3 is 45.

that looks something like this

12+\frac{1}{2}x= 45

which can be solved as such

\frac{1}{1} x+(12-3)=45\\\frac{1}{2}x+9=45\\\frac{1}{2}x=45-9\\ \frac{1}{2}x=36\\\frac{2}{1}*\frac{1}{2}x=36*\frac{2}{1} \\  x=36*2\\x=72

What are the terms in the expression 2x−4y+8 ?
vazorg [7]

Answer:

A. 2x, -4y, and 8

Step-by-step explanation:

If there is a minus sign in front of the 4 (-), add that to the expression. What you are just simply doing is separating the numbers up. For example:

12x - 8y + 4x

Now here, you have two of the same variables (x, y, etc). So, what you do is look at the last number that has the same variables, which is 4, and look at what the problem you will be solving, which is addition. So, very simply, you add then together!

12× + 4× = 16×

As you can see I kept the same variable. This is because, well, it is the same! Simply, just substitute in the 16× with the 8y. Now here is the tricky part, for some people. Do you see that there is a negative sign in front of the 8 (-)? Well! You have to substitute that in with the expression. No adding this or anything, just simply slide it next to the 16× because, we can not add nor subtract it with the 8y just because it has a different variable.

Your example answer would be: 16× - 8y

Hope this helps!

P.S. if you think this helped you at all, Brainliest me if ya want to. Have a great day!
