Answer:
x= -2 and y= 8
Step-by-step explanation:
8x+5y=24-------A
y=-4x---------B
Putting the value of y from B in A
8x+5(-4x)=24
8x +(-20x)= 24
8x-20x=24
-12x=24
x= -24/12
x=-2--------C y =-4(-2)=8
N^2.....because this is the product of n and itself, not the sum

Simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.




(good luck :) and mark me brainliest if you're satisfied with my answer)
