Answer:
Step-by-step explanation:
5x + 2y = - 2
2y = - 5x - 2
y = x - 1
a) 4, b) 10
a)
1) - 7 + 3 = - 4
2) | - 4| = 4
b)
1) |- 7| = 7
2) 7+3 = 10
A≈28647.89m²
Circumference 600m
Using the formulas
A=πr2
C=2πr
Solving for A
A=C2
4π=6002
4·π≈28647.88976m²
28 dollars
$45+$5= $50 which is how much she spent it total
then she sells it for $78
so her profit would be $28
1012.5
