Hatshy [7]

Answer:

$\boxed{ \text{B. 10 weeks, \$310 }}\\$

Step-by-step explanation:

We have two conditions:

$\begin{array}{lrcll}(1) & y & = & 25x + 60 & \\(2) & y & = & 30x + 10 & \\ & 25x + 60 & = & 30 x + 10 & \text {Set (1) = (2)} \\ & 50 & = & 5x & \text{Subtracted 25x from each side} \\& x & = & 10 &\text{Divided each side by 5} \\\end{array}\\$ $\\\boxed{ \textbf{The number of weeks is }x = 10}\\$

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

Heather: y = 30x + 10 = 30(10) + 10 = 300 + 10 = 310

brian invests £4700 into his bank account he recieves 5.5% compound intrest how much will brian have after 3 years?

alexandr1967 [171]

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

For f(x)= 4x+1 and g(x) = x squared -5 , find (f-g)(x)

makvit [3.9K]

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
