Is f of x always equal to g of x

Mathematics

Mars2501 [29]3 years ago

Of course not. 

' f(x) ' is the description of a function,and ' g(x) ' is the description of
a function.  There are an infinite number of different possible functions,
so f(x) and g(x) are usually not the same one.

f(x) is equal to g(x) for any 'x' only when the two descriptions are the
same function.  Otherwise f(x) is equal to g(x) only at the points where
their graphs intersect.

The length of a rectangle is twice its width. if the area of the rectangle is 200 yd2 , find its perimeter.
Lorico [155]
Width: x
Length: 2x
Area=x(2x)=2x^2
2x^2=200
x^2=100
x=10 or -10(reject as x>0) [width cannot be less than 0, doesnt make sense]
Perimeter
=x+x+2x+2x
=6x
=6(10)
=60 yd

Point A (-6, 2) and B (4, k) lie on a line that has a slope of 3/5 Determine the value of K
____ [38]

Answer:

k=8

Step-by-step explanation:

We can solve using the slope formula

m= (y2-y1)/(x2-x1)

3/5 = (k-2)/(4- -6)

3/5 = (k-2)/(4+6)

3/5 = (k-2)/10

Multiply each side by 10

10*3/5 = (k-2)/10 *10

6 = k-2

Add 2 to each side

6+2 = k-2+2

8 = k

Karen's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 57 liters. What
guapka [62]

Answer:

Karen has to at least spend 11 minutes.

Step-by-step explanation:

This is because 57 - 13 = 44. 44 divided by 4 = 11. This means that in 11 minutes Karen will have a 57 liter tank. But she could keep going, but the least number of minutes would be 11 minutes, to get to 57 liters.

I hope this helps! Please mark me Brainliest if it did! Thank you and have a nice day!

How many solutions does the equation have?
SSSSS [86.1K]
Let's solve and find out.

4(2n - 4) + 3 = 8n - 19
8n - 16 + 3 = 8n - 19
8n - 13 = 8n - 19
-13 = -19

-13 and -19 are not equal, so the equation has no solutions.
