Hey I have posted a picture the method I use to solve simultaneous equations is change the sign and follow the new sign.
This involves changing the sign for the second equation and solving it
Answer:
-63
Step-by-step explanation:
Write the problem as a mathematical expression.

Simplify 4−4−8 to substitute in f(x)=−x^2+1
Subtract 4 from 4

Subtract 8 from 0

Replace the variable x with −
8 in the expression

Simplify


Answer = -63
Plz give me Brainliest if you can, hope this helps.
Answer:
The other endpoint would be (-13, -11)
Step-by-step explanation:
In order to find the coordinates of an end point, we need to note that the midpoint would be the average of the two values. We'll call the unknown point P and we'll start by looking at the x values only.
(1 + Px)/2 = -6 ----> multiply by 2
1 + Px = -12 -----> subtract 1
Px = -13
Now we can do the same with the y values.
(7 + Py)/2 = -2 ----> multiply by 2
7 + Py = -4 ------> subtract 7
Py = -11
