Answer:
(5,1) is not a solution of the above system of equations.
Step-by-step explanation:
We are given a system of equations that are
- 5y = - 5 ......... (1) and
7x + 6y = 7 ........... (2)
So, solving equation (1) we get y = 1 and putting y = 1 in the equation (2) we get 7x = 7 - 6(1) = 1
⇒
So, it clear from the solution of the above equations i.e. (), we can say that (5,1) is not a solution of the above system of equations. (Answer)
Answer:
The x-intercept is (3,0).
The vertex of the function is (3,0).
Step-by-step explanation:
Given : Function
To find : What are the x-intercept and vertex of this quadratic function?
Solution :
Function
The x-intercept is when g(x)=0.
i.e.
Divide by -5 both side,
Taking root both side,
Add 3 both side,
The x-intercept is (3,0).
The general vertex form of the quadratic function is
where, (h,k) is the vertex
Compare the given function
a=-5 , h=3 and k=0
The vertex of the function is (3,0).
