where do they intersect?
they intersect at 3 different places
can you tell me the order pairs?
Ok one second
correct that's one of them what's the x value in (-1,0)?
that's your answer
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 ^_^
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?
There is no graph for this question
ok so if they are equal, that means they are the same number
when x = 5 \(f(5) = g(5)\)
meaning their outputs are the same
you want an example?
ok let's say your equations are \(f(x)=2x+11\\g(x)=3x+6\)
and they say x = 5
\(f(x) = 2*5+11\\2*5=10\\10+11=21\\f(x)=21\)
oh i see...
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!!!!!!!
