Answer:
y = x - 8
Step-by-step explanation:
There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!
Looking at inputs 20 and 21, the outputs are 8 less than the inputs. Check the other inputs and notice that the same pattern holds up.
Answer:
The numbers are -21 and 21
Step-by-step explanation:
Let
x ----> one number
y ----> another number
S----> the sum of their squares
we know that
----> equation A
----> equation B
substitute equation A in equation B
This is the equation of a vertical parabola open upward
The vertex is a minimum
Find the coordinates of the vertex
Using a graphing tool
The vertex is the point (21,882) ----> see the attached figure
we have
x=21
<em>Find the value of y</em>
therefore
The numbers are -21 and 21
Answer:
Square pyramid
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
The line parallel to x=8 is another vertical line:
x = constant
To make it go through a point with an x-coordinate of -3, the constant must be -3.
Your line is ...
x = -3
