Answer:
The point for the given linear equations is (
,
)
Step-by-step explanation:
Given as :
The two linear equations are
First equation
y =
x + 5
Or,
y +
x + 5 = 0
Taking LCM we get
y + x + 10 = 0 .......1
Second equation
y = 2 x + 2 ........2
Now solving both equation
Putting the value of y from eq 2 into eq 1
(2 x + 2) + x + 10 = 0
Or, 3 x + 12 = 10
Or, 3 x = 10 - 12
Or, 3 x = - 2
∴ x = 
Now putting the value of x into eq 2
∵ y = 2 x + 2
Or, y = 2 ×
+ 2
Or, y =
+ 2
Or, y = 
∴ y = 
So, The points are (x , y ) = (
,
)
Now, plotting the points on x-y coordinate graph
Hence, The point for the given linear equations is (
,
) Answer
Answer:
-5
Step-by-step explanation:
Given the functions
f(x) = 2x - 20
g(x) = x - 1
f(x)/g(x) = 2x - 20/x-1
f/g(x) = 2x - 20/x-1
Substituting x = -5 int the result
f/g(5) = 2(5) - 20/5-1
f/g(5) = 10 - 20/4
f/g(5) = -10/4
f/g(5) = -5
Hence the result is -5
