Step-by-step explanation:
hope this will help you.
The four-fifths of a number, in this case, z is four times the number divided by z. That is 4z/5. When we add six to the product and equate the expression to 8, we get,
4z/5 = 8
The value of z from the equation is 10.
Hi there!

Evaluating f(x) at x = 9 means we must use the piecewise function where x = 9 is included.
f(x) = 12 includes 9 because a "≤" is inclusive of the interval. Thus:
f(9) = 12
Maybe 6 but I’m not sure.
Answer:
£300
Step-by-step explanation:
We apply the formula for Simple Interest:

where P = Principal
R = Rate of interest
T = Time elapsed (in years)
We are given that P = £5000, R = 3%, T = 2 years
The interest after 2 years will be:

I = £300
The interest Becky will get after 2 years will be £300.
