Answer:
x=0.8
Step-by-step explanation:
-5x + 4= 0
-4 -4
-5x=-4
÷5
-x=-0.8
x=0.8
Answer:
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,
![{x}^{3} - y^{3}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B3%7D%20-%20y%5E%7B3%7D%20)
![= {8}^{3} - {2}^{3}](https://tex.z-dn.net/?f=%20%3D%20%20%7B8%7D%5E%7B3%7D%20%20-%20%20%7B2%7D%5E%7B3%7D%20)
=512-8
=504
Hope this helps!
