Scale factor is defined as
s=size of image / size of preimage.
Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.
So scale factor = B'O'/BO = 9/27 = 1/3.
Range = <span>{f(x) | f(x) ≥ –4}</span>
Answer:
the slope is -2/7
Step-by-step explanation:
<u>-5+1= -4</u>
21-7= 14
-4/14 = -2/7
Answer:
x ≤ 
Step-by-step explanation:
multipy both sides by twelve
move the variable to the left side and change the sign
collect like terms
divide both sides by -17 and flip the inequality sign
Answer: for 3) 427 hikers
Step-by-step explanation: b + 178 + b = 676
2b + 178 = 676
2b = 498
b = 249 bikers
h = 249 + 178 = 427 hikers
