Answer:
sorry i didn't get it
Step-by-step explanation:
Given:
The equation of the curve is:

To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,

Differentiate the given equation with respect to x.


Now we need to find the value of this derivative at (2,7).




Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
Step-by-step explanation:
Linear equations. Make 2 new equations from the question. Name the first number as x and the second as y...
Answer:
-1.5
Step-by-step explanation:
The distance between S and T is
4 - -7
4+7 = 11
Divide this in half to find the midpoint
11/2 = 5.5
Add this to point S to get the point itself
-7 + 5.5 = -1.5
