answer:
slope: -2/3
step-by-step explanation:
y=mx+b
m represents the slope, and b the y-intercept.
rearrange: 9x= -6y+18
---> -6y= -9x-18
divide all terms by -6.
-6y/-6= -9/-6x-18/-6
y= 3/2x+3 (slope/intercept form)
m= 3/2
---> 1/3/2= -2/3
Ok let's understand the question.
We want to know what values we get when n is positive in 1/n.
We get the values
0<1/n≤1
If we plug in 1: 1/1 = 1
2: 1/2 = .5
100: 1/100 = .01
10000000 = 1/10000000 = Small number close to 0.
n will always be more than 1 by the given (n>0).
Answer:
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
Step-by-step explanation:
Given;
Cost of car insurance last year C1 = £256
Cost of car insurance this year C2 = £894
Percentage increase = change in cost/initial cost × 100%
%∆C = ∆C/C1 × 100%
%∆C = (C2-C1)/C1 × 100%
Substituting the given values;
%∆C = (894-256)/256 × 100%
%∆C = 249.21875%
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
