Answer:
1st one 6x is greater than or equal to 120
Step-by-step explanation:
because it sys she needs to read 120 so it cant be 6x is less than or equal to 120
(x-y) ² - x+y
x ² - 2xy + y ² - x + y
or
x(x-1) + y(y+1) - 2xy
no
cant explain jus nonono
21+10.5
=31.5 ²

Vertex form
You convert to vertex form a(x - b)^2 + c . The coordinates of the maxm/minm will be (b, c).
For example find minimum value of x^2 + 5x - 6:-
x^2 + 5x - 6
= (x + 2.5)^2 - 6.25 - 6
= (x + 2.5)^2 - 12.25
The coordinates of minimumm will be (-2.5, -12.25) The values of the minimum of the function is -12.25
Answer:it's C!!
