C. The vertexes are the same. The functions' vertex (h,k) values were not altered, just a (stretch/compress).
Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5
Answer:6.774 gallons
Explanation: They drove 210 miles with 31 miles per gallon. So you divide 220/31=x
X=6.774 gallons
M=Y2-Y1/X2-X1
M= 1250-1625/4-2.5
M=841.25
But I have no clue how you would graph that
He could have 30 dimes and 13 quartars
