Step-by-step explanation:
First find the gradient. Then, find out the y-intercept then substitute into y=mx+c
Answer: 15%
Step-by-step explanation:
% change = change/ actual value x 100
Change = 11 .50 - 10 = 1.5
Therefore % change = 1.5/10 x 100
= 15%
Answer:
No solution
Step-by-step explanation:
2x+20-2x=2x-4-2x
20= -4
answer is No Solution
-4= Contraction
2.5=Expansion
2/3= Contraction
-3/4= Contraction
Best way to solve this, if the scale factor is less than one, is a contraction. If it is greater than one, than it is an expansion.
