The amount that'll be saved if the television was bought for cash is $1600.
Cash price of television = $10000
Amount paid through hire purchase will be:
= (20% × $10000) + ($800 × 12)
= (0.2 × $10000) + $9600.
= $2000 + $9600.
= $11600
The amount that could have been saved will be:
= $11600 - $10000.
= $1600

Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point 
value of first point) divided by (x value of second point 
value of first point):
------------------------------------------------------------------------
The slope for a perpendicular line is 2.
Ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142
hope this helped
Answer:part a :yes it is a linear function because it is a straighten lined Part b : LINEAR FUNCTION Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. NONLINEAR FUNCTION An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.

Answer:
2d(d³-9d-30)
Step-by-step explanation:
2d⁴ - 6d - 18d² - 54d
= 2d⁴- 18d²-60d
=2d(d³-9d-30)
