How many solutions does the system: picture have?

Mathematics
1 answer:
joja [24]4 years ago
4 0

Answer:

The system has one solution

Step-by-step explanation:

we have

9x+y=3 ------> equation A

9x-y=7 ------> equation B

Adds equation A and equation B

9x+y=3\\9x-y=7\\-------\\9x+9x=3+7\\18x=10\\x=10/18\\x=5/9

find the value of y

9(5/9)-y=7

5-y=7

y=5-7=-2

The solution is the point (5/9,-2)

F(x)= 3x + 1
f(x)= 3(3) + 1
= 9 + 1
= 10

g(x)= 4x - 5
= 4(3) - 5
= 12 - 5
= 7

So... A. f(x) is greater when x=3

Which graph represents the following piecewise defined function?
kenny6666 [7]
The correct answer is shown in attached figure
To find the correct graph, we should study the continuity of the function

Check the continuity at x = -2
from the left ⇒⇒ f(-2) = 1/2 * -2 + 3 = 2
from the right ⇒⇒ f(-2) = 2
∴ The function is continuous at x = -2

Check the continuity at x = 3
from the left ⇒⇒ f(3) = 2
from the right ⇒⇒ f(3) = 2*3 - 3 = 3
∴ The function is jump discontinuous at x = 3


From the previous results the correct graph is the last as shown in attached graph.

Which description compares the vertical asymptote(s) of Function A and Function B correctly?
r-ruslan [8.4K]
Function A:  f(x)=\frac{1}{x}+4.  Vertical asymptotes are in the form x=, and they are a vertical line that the function approaches but never hits.  They can be easily found by looking for values of <em>x</em> that can not be graphed.  In this case, <em>x</em> cannot equal 0, as we cannot divide by 0.  Therefore <em>x</em>=0 is a vertical asymptote for this function.  The horizontal asymptote is in the form <em>y</em>=, and is a horizontal line that the function approaches but never hits.  It can be found by finding the limit of the function.  In this case, as <em>x</em> increases, 1/<em>x</em> gets closer and closer to 0.  As that part of the function gets closer to 0, the overall function gets closer to 0+4 or 4.  Thus y=4 would be the horizontal asymptote for function A.
Function B:  From the graph we can see that the function approaches the line x=2 but never hits.  This is the vertical asymptote.  We can also see from the graph that the function approaches the line x=1 but never hits.  This is the horizontal asymptote.
