How would I solve this?? 5p-8(p+1)>16
alexandr402 [8]

<em>*To solve inequalities is similar to solving equations: isolate the desired variable to one side.</em>

So firstly, distribute -8 to (p + 1):

5p-8p-8>16

Next, combine like terms:

-3p-8>16

Next, add 8 to both sides:

-3p>24

Lastly, divide both sides by -3. Now since you are dividing by a <u>negative</u>, you will be flipping the inequality symbol as well.<u> Your final answer will be p</u>

What two positive real numbers whose product is 50 have the smallest possible sum?
Llana [10]
X * y = 50
y = 50 / x
S = x + y = x + 50 / x
S` = 1 - 50 / x²
1 - 50 / x² = 0
50 / x² = 1
x² = 50
x = √ 50 = 5 √2
y = 50 / 5√2 = 5 √2
Answer:
Those numbers are: x = 5√2 and y = 5√2.

2x+3y=6 fins the slope of the line
klasskru [66]
2x + 3y = 6

Put this into y=mx+b form (which is also called slope-intercept form)

Where m=slope and b=y-intercept

In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s

3y = 6 - 2x

Then, divide both sides by 3 so that we fully isolate y.

3y ÷ 3 = (6 - 2x) ÷ 3

Simplify.

y = 2 - 2/3x

Put this into order by moving "x" onto the correct place.

y = -2/3x + 2

Therefore -2/3 is the slope, as it is in the "m" spot.

Hope I helped! :)
