Answer:
(8,-1)
Step-by-step explanation:
Given :
To Find: solution of given system of equations.
Solution:
Equation a :
Equation b :
Substitute the value of y from equation b in equation a
y from equation b : y = 7-x
Now substitute value of y in equation a
Thus equation a becomes:
⇒ x= -1 and x = 8
Now substitute values of x in equation b to obtains values of y
⇒
for x = -1
⇒
⇒
⇒
Thus (x,y)=(-1,8)
For x =8
⇒
⇒
⇒
Thus (x,y)=(8,-1)
Hence Option A is the correct solution .
Answer:
Graph (2).
Step-by-step explanation:
Given question is incomplete: Find the complete question in the attachment.
Given : f(x) = -
g(x) = - 1
To find : The graph showing f(x) = g(x)
If the given functions f(x) = g(x)
= 1
x = -2
That means both the functions have the same value at x = -2
f(-2) = g(-2) = -1
In other words, both the lines will intersect at a point (-2, -1).
From the given graphs,
Graph number (2) shows the required results.
A straight line g(x) = -1 parallel to x- axis and another straight line f(x) = , intersect each other at (-2, -1).
Therefore, Graph (2) will be the answer.
