Bella: y = 25x + 60 = 25(10) + 60 = 250 + 60 = 310
Heather: y = 30x + 10 = 30(10) + 10 = 300 + 10 = 310

Answer:
Brian will have £817.8
Step-by-step explanation:
Principal = £4700
interest = 5.5% = 0.055
n = 3 years
Amount = [(Principal * (1 + interest)ⁿ) - Principal]
Amount = [(4,700 * (1 + 0.055)³) - 4,700]
Amount = [(4,700 * (1.055)³) - 4,700]
Amount = [(4,700 * 1.174) - 4,700]
Amount = [5,517.8 - 4,700]
Amount = £817.8
Hope i am not wrong
f(x)=4x+1
g(x)=x^2-5
(f-g)(x)=f(x)-g(x)
(f-g)(x) =4x+1-x^2+5
-(x^2-6-4x)
solve it for x
