1-4y^2 in factored form
Anastasy [175]

Answer:

(1 -2y)(1 +2y)

Step-by-step explanation:

The difference of squares is factored as ...

... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy

Here, you have a=1, b=2y, so your factored form is ...

... 1 -4y² = (1 -2y)(1 +2y)

Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed
swat32

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

h=\frac{1.150}{60} \\h=2.5

Now we determine the distance Michael traversed during those 2.5 hours:

d_{1} =2.5.75 \\d_{1} =187.5\\

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

d_{2} =2.81 \\d_{2} =162

He also traveled 162 miles

Finally we add both traversed distances:

d_{t}=187.5+162 \\d_{t}  =349.5\\

So , he traveled a total of 349.5 miles.

Which graph shows a function whose inverse is also a function?
-BARSIC- [3]

Answer:

<u>Option C.</u>

Step-by-step explanation:

See the attached figure which represents the graph of the given options.

To determine if a line represents a valid function, we may use the vertical line test.

If it is touching more than one point on the line at a time, the line is not a valid function.

So, according to the previous rule, the function of figure C is a function and its inverse is also a function.

<u>The answer is option C.</u>

There are a total of 122 countries in Africa, Europe, and North America (as of 2003). Europe has twice as many countries as Nort
Eddi Din [679]
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N

(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America

E = 2N
E = 2(23)
E = 46 <== Europe

A = 7 + E
A = 7 + 46
A = 53 <=== Africa
