gradient = 9

Step-by-step explanation:

The gradient of the tangent at x = a is the derivative

Differentiate using the power rule on each term

(a ) = na and ( constant ) = 0

y = 2x² + 5x - 3

= 2.2 + 5 - 0

    = 4x + 5

( x = 1 ) = 4(1) + 5 = 4 + 5 = 9 ← gradient of tangent

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
