can you tell me the order pairs?

(-1,0)...
Mehek14
  • Mehek14
correct that's one of them what's the x value in (-1,0)?
anonymous
  • anonymous
-1
Mehek14
  • Mehek14
that's your answer
Mehek14
  • Mehek14
the other solutions are x = -2.5 and x = 1.5 however, they aren't in your choices the only one that is is x = -1

(-3.75,-2.75) is the second coordinate and the third is around (2.5,3)

Oh ok thank you! I get it now

your welcome ^_^

Can you help me on one more? @Mehek14

Ok so I know you told me when the two lines intersect, you get the coordinates and the x value to find the solution...so would the answer to the question I am about to put be A.

For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at x = 5. What is definitely true about x = 5? A. Both f(x) and g(x) cross the x-axis at 5. B. Both f(x) and g(x) cross the y-axis at 5. C. Both f(x) and g(x) have a maximum or minimum value at x = 5. D. Both f(x) and g(x) have the same output value at x = 5

is this with the same graph?
anonymous
  • anonymous
No
anonymous
  • anonymous
There is no graph for this question
Mehek14
  • Mehek14
ok so if they are equal, that means they are the same number
Mehek14
  • Mehek14
when x = 5 \(f(5) = g(5)\)
Mehek14
  • Mehek14
meaning their outputs are the same
anonymous
  • anonymous
Oh ok
Mehek14
  • Mehek14
you want an example?
anonymous
  • anonymous
yes please
Mehek14
  • Mehek14
ok let's say your equations are \(f(x)=2x+11\\g(x)=3x+6\)
Mehek14
  • Mehek14
and they say x = 5
Mehek14
  • Mehek14
\(f(x) = 2*5+11\\2*5=10\\10+11=21\\f(x)=21\)
anonymous
  • anonymous
oh i see...
Mehek14
  • Mehek14
\(g(x)=3*5+6\\3*5=15\\15+6=21\\g(x)=21\)
Mehek14
  • Mehek14
so \(f(x)=g(x)\) because when you put x = 5 for both equations, they both have the same answer = 21

Omg i get it! Thank you so much!!!!!!!
