F(b)=7b+8
you just need to change the x variable. make y into f(x) or in this case f(b)
Answer:
B
Step-by-step explanation:
Answer:
The point of intersection of these two equation is 1 , 6
Step-by-step explanation:
Given as :
The two equation of line are
y = 4 x + 2 ........1
y = - x + 7 ........2
Let The point of intersection of these two equation = p (
)
Now, solving the equation 1 and 2
So, 4 x + 2 = - x + 7
Or, 4 x + x = 7 - 2
Or, 5 x = 5
∴ x = 
i.e x = 1
Again
put the value of x in eq 2 , we get
∵ y = - x + 7
Or, y = - 1 + 7
Or, y = 6
so, The point of intersection of these two equation = p (
) = 1 , 6
Hence. The point of intersection of these two equation is 1 , 6 Answer
If its m-4 + 1/5-4, it's b
if you meant m^-4 + (1/5)^-4, it should be a
