-6x-6=x²-5x-6
x²+x=0
x(x+1)=0
x=0, x=-1
x=0, y=-6x-6=-6*0-6=-6 (0,-6)
x=-1, y=-6x-6=-6*(-1)-6=0 (-1,0)

Answer (-1.0) and (0,-6) . The last one.

Check
(0,-6), y=-6-x, -6=-6-0, -6=-6 True
y=x²-5x-6, -6=0+0-6, -6=-6, True
(-1,0),y=-6-x, 0=-6-(-6), 0=0 True
y=x²-5x-6, 0=1²-5(-1)-6=1+5-6=6-6=0, 0=0 True,

So,
Answer (-1.0) and (0,-6) . The last one.

How do you do inequalities

fgiga [73]

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!

Simplify the expression below. Then classify the resulting expression

evablogger [386]

Answer:

Simplified = 5

Classification = Monomial

Step-by-step explanation:

<h2>PART I: Simplify the expression</h2>

<u>Given expression:</u>

3x² + 6x + 5 - 3x (2 + x)

<u>Expand parenthesis by distributive property:</u>

= 3x² + 6x + 5 - 3x (2) - 3x (x)

= 3x² +6x + 5 - 6x - 3x²

<u>Put like terms together:</u>

= 3x² - 3x² + 6x - 6x + 5

= 0 + 0 + 5

= $\boxed{5}$

<h2>PART II: Classify polynomial</h2>

<u>Concept:</u>

Polynomial is classified by the number of terms a polynomial has.

Monomial: a polynomial with only one term
Binomial: a polynomial with two terms
...

<u>Classify the given expression:</u>

Original = 3x² + 6x + 5 - 3x (2 + x)

Simplified = 5

5 is a constant and it has only one term

Therefore, it is a <u>monomial</u>.

Hope this helps!! :)

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:

lisabon 2012 [21]

Answer: The speed of the motorboat is 70 miles per hour

Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.

For example, at 2 hours, the distance shown on the graph is 175 miles

Subtract: 175 -35 = 140. Then divide 140/2 = 70

At 4 hours, the distance shown is 315 miles.

Subtract: 315 - 35 = 280. Then divide 280/4 = 70

70 mph is the speed.
