Answer:
Infinity
Step-by-step explanation:
Since 
for all real numbers x, this property is also true for x=1, which tells us that
On the other hand, note that for all real numbers x, it holds that
Therefore, if
we have tat
The last reasoning tells us that the property holds for all real numbers x if an only if 
Therefore, we can choose arbitrary constants a and b as long as
We can choose a and b such that both positive, both negative or one of the two constants is equal two zero. In the first two cases
can get as big as we want, depending on the constants, and we are done.
Answer:
A, 11
Step-by-step explanation:
Answer:
infinitely many solutions
Step-by-step explanation:
Let's first eliminate y^2.
To accomplish this, divide the 2nd equation by 5, obtaining
y^2 = 5/2 - x^2. Now substitute this result for y in the first equation:
(-1/3)x^2 = -5/6 + (1/3)(5/2 - x^2), or
-x^2 -5 5 x^2
-------- = ------ + ------- - -------- and this simplifies to:
3 6 6 3
-x^2 x^2
------- = - ------- which is an identity and is thus always true.
3 3
Thus, any value of x will satisfy this equation; there are infinitely many solutions.
To solve this exercise you must apply the proccedure shown below:
1- You have the following numbers given in the problem above:
3/81, 3/4 and 1.25
2- Therefore, you have that 3/81 in decimal form, is:
3/81=0.03
3- 3/4 in decimal form is:
3/4=0.75
3- Keeping this on mind, you can draw the number line from 0 to 2 and write the numbers given above, as you can see in the figure attached.
Answer:
0.7
