Well I think I can help you out ...
if you assume input x=2
the output will be as following :
y= -1/3(2)+2
=-2/3+2
=-2/3+6/3
=(-2+6)/3
=4/3
=1.333
Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is <em>x</em> percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is <em>discounted. </em>If it's now selling for 70%, it has been discounted 30%. So the answer is 30%
The equation of a straight line with gradient m passing through the origin is:
The line passes through the origin, so the y-intercept is

scale factor is the ratio of two similar geometric figures of their
corresponding sides. The scale factor is calculated by locating the
corresponding sides on each figure. We do as follows:
256/x = 4/9
x = 576 m^2
side length = 24 m
Hope this answers the question. Have a nice day. </span>
