Answer: # 15 is x=-12 and #16 is x=24
Step-by-step explanation:
Answer:
Both are similar by SAS similarity.
This SAS similarity is equivalent to the congruence.
Step-by-step explanation:
Step 1:
To prove that ACB and HIG as similar triangles.
We have to look upon the corresponding sides.
SAS= Side angle sides , there the angle must be in between two sides.
ACB =
HIG
Lets work on the corresponding sides.
IG/AC = IH/AC
= 
Reducing each to lowest form, we divide numerator and denominator by 3 for the 1st fraction and by 4 for the 2nd fraction.
We have
= 
Both sides are equal.
So its proved that both are similar with SAS similarity theorem.
-2(-2)+3=7
-2(0)+3=3
-2(4)+3=-5
22,189 - 16,789 = 5400....so she drove/rode 5400 miles in 15 days
5400/15 = 360 miles per day <==
Answer: f^-1(x)= 2-4x/3
This is because the power of f is -1
