Combine like terms
1. Add 3b and 5b (combine like terms)
2. After adding you are supposed to get 8b
3. The -2 would stay as it is because we can't add it to 8b
4. So the answer would be 8b-2
The X coordinates are the bottom part of a graph and Y coordinates are at the up & down part of a graph. Hopefully that answers your question.
According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:
x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
Answer: 275$
I'm not entirely sure I did this right! But at least try!!!
Step-by-step explanation:
20/100 = 55/x (cross multiply)
20x = 5,500 (divide)
X = 275
