Answer:
dy/dx= 7- 3x^-1/2
when X=1
dy/dx = 4
as it is a tangent M1=M2=4
now,
at gradient 4 and point (1,1)
equation of curve is ,
y-y1= m(x-x1)
or, y-1=4(x-1)
or, y-1=4x-4
or, y-4x= -3
or, 4x-y=3

Answer:
m = 16
Step-by-step explanation:
Given expression 2m−13 and m+3.
We have to find value of m for which both the expression are equal.
To find that value we will equate both the expression and solve as given below
2m−13 = m+3
adding 13 on both LHS and RHS
2m−13 + 13 = m+3 + 13
=> 2m = m +16
subtracting m from LHS and RHS
2m - m = m +16 - m
=> m = 16
Thus, value of m will be 16.
to validate this lets put value of m as 16 in both the equation
2m - 13 = 2*16 - 13 = 32-13 = 19
m+3 = 16+3 = 19.
Thus, we see for m = 16 , both expression has equal value which is equal to 19.
