The formula for the cost of buying a car is:
cost = 12 x monthly payment + deposit
a) Find the cost of a car when the monthly payment is £350 and
the deposit is £2 000.

£6200

Step-by-step explanation:

Given the formula for cost of a car = 12 x monthly payment + deposit,

where monthly payment = £350 and deposit = £2000

Insert the values into the formula:

Cost of the car= 12 (£350) + £2000

Multiply 12 by £350, then add £2000

= 12 x £350 + £2000

£4200 + £2000

=£6200

Therefore, Cost of the car is £6200

the answer is d

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
