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

Answer: 120
Step-by-step explanation:
The total number of digits from 1 to 9 = 10
The number of digits from less than 5 (0,1,2,3,4)=5
Since repetition is not allowed so we use Permutations , then the number of 3-digit different codes will be formed :-
The number of digits from greater than 4 (5,6,7,8,9)=5
Similarly, Number of 3-digit different codes will be formed :-
Hence, the required number of 3-digit different codes = 60+60=120
