20*3/4 = 60/4....and 60/4 = 15
The answer is -9 because you have to multiply the two numbers.
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%
Answer:
c-10
Step-by-step explanation:
point slope form
y-y1 = m(x-x1)
y-1 = 6(x-(-2))
y-1 = 6(x+2)
to change it into slope intercept form
distribute
y-1 = 6x+12
add 1 to each side
y = 6x+13
the y intercept is 13
