Tom is applying for a visa.
alexdok [17]

Answer:

£210

Step-by-step explanation:

Given that :

Visa cost = £2300

7% charge of visa price = (0.07 * £2300) = £161

Total cost = £(161 + 2300) = £2461

Amount to be saved per month = £2461 / 12 = £205.08333

= £210 (nearest £10)

PLZ ans have mocks plz
Yanka [14]

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

y=5-x^{2}

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

y(-2)=5-(-2)^{2}=5-4=1

Doing the same with the other x values we have:

y(-1)=5-(-1)^{2}=5-1=4

y(0)=5-(0)^{2}=5

y(1)=5-(1)^{2}=5-1=4

y(2)=5-(2)^{2}=5-4=1

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 1

I hope it helps you!
