Apply fraction rule to flip the second fraction to times the two fractions...

< x^2+8 / 2x^2+x-3 * x-1 / x+2 >

Then you can multiply the fractions:
< (x^2+8)(x-1) / (2x^2+x-3)(x+2) >

Factor (2x^2+x-3) as (x-1)(2x+3) so we can cancel out (x-1) from the denominator and numerator < (x^2+8)(x-1) / (x-1)(2x+3)(x+2) >
< = x^2+8 / (2x+3)(x+2) >

Expand denominator (2x+3)(x+2) with foil method shown in image:

Therefore the answer is < = x^2+8 / 2x^2+7x+6 >

How do you do equations and equalities on a number line
castortr0y [4]
To graph an equation on a number line, You place a point at where the number lies. For example, x=5 would mean that you place a point on 5 and not draw a line.

To graph an inequality on a number line, if depends if it is <, >, ≤, or ≥ . If it is ≤, it is a closed point on the number and a line moving to the left of the number. If it is a ≥, then it is a closed point on the number with a continuous line to the right. If it is a <, it is an open point on the number with a line going to the left. If it is a >, then it is an open point going to the right.

I'll attach a photo to show you what it looks like! :) Hope this helps! :)

Dy/dx when y=x^2e^5x
vekshin1
I believe the problem asks for the slope. This problem can be done by putting <span>y=x^2e^5x into slope intercept form. However, the issue is that there is the variable "e", which does not match the slope intercept formula, y=mx+b. Long explanation short, the slope is </span>3e^5x^2

TIME REMAINING
Leya [2.2K]

Answer:

w=-7/2z

Step-by-step explanation:

to solve for w you firstly have to group the like terms

5w-3w=2z-9z

2w=-7z

then you have to divide both sides by 2 inorder to remain with w on one side.

2w/2=-7/2

w=-7/2

I hope this helps
