How do you do inequalities

1 answer:

8 0

So some quick tips for inequalities:
**What you do to one side you HAVE TO do it to the other 2**
**If you ever divide a negative number past the inequality signs, the signs FLIP!!**
(e.g. 2>-5x>25)
-2/5 <x < -5

I hope that this has helped!

Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = 2x - 7

y = -x + 5

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y</em>: 2x - 7 = -x + 5
[Addition Property of Equality] Isolate <em>x</em> terms: 3x - 7 = 5
[Addition Property of Equality] Isolate <em>x</em> term: 3x = 12
[Division Property of Equality] Isolate <em>x</em>: x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

Define original equation: y = -x + 5
Substitute in <em>x</em>: y = -4 + 5
Add: y = 1

Find the volume of a cylinder with height 6.3 m and diameter 4 m. Use pi = 3.14

telo118 [61]

$volume \: of \: cylinder \: = \pi {r}^{2} h$
diameter = 4m
radius = 4/2
= 2m

volume = (3.14)(2^2)(6.3)
= 79.128m^3
