Answer:
3x^2+14x-5
Step-by-step explanation:
Use the foil method. Multiply 3x by (x+5) first, then multiply -1(x+5). This produces 3x^2+15x-x-5, reduce to get 3x^2+14x-5.
Answer:
x= 14 y= 13
Step-by-step explanation:
Use substitution or elimination
Answer:
The value of Liam's investment at the end of 4 years is £9069.764
Step-by-step explanation:
Compound interest is interest calculated on the initial principal, which also includes all of the accumulated interest of previous periods of an investment.
We multiply the principal amount by one plus the annual interest rate to the power of the number of compound periods to get a combined figure for principal and compound interest.
4.5% in the first year;
4.5/100 = 0.045
(1 + 0.045) × 8000 =
1.045 × 8000 = £8360.
2.75% for all subsequent year;
2.75/100 = 0.0275
1 + 0.0275=1.0275
Number of years is;
4-1=3years
Therefore,
8360 × (1.0275)^3 =
8360 × 1.0849 = £9069.764
Answer:
f(-2) = 2
Step-by-step explanation:
The question is asking you to find the y value when the x value is -2. When observing the graph, we can see when the x value is -2, the y value is 2. Therefore, f(-2) = 2.
