1 answer:
Answer:
The solution is x=2
Step-by-step explanation:
<u><em>The correct question is</em></u>
Graph f(x) = 2x +1 and g(x)=-x+7 on the same coordinate plane.
What is the solution to the equation f(x) = g(x)?
we have
we know that
The solution for the equation f(x)=g(x) is the x-coordinate of the intersection point both graphs
using a graphing tool
The intersection point is (2,5)
The x-coordinate of the intersection point is 2
therefore
The solution is x=2

Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:
First, let's isolate x in equation A:
Now, we will replace where's x by 11-y in equation B:
As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
