Rise over run: I counted 3 units up and then 2 times to the right which makes the slope 3/2.
Answer:
the answer should be 2.04
Step-by-step explanation:
Answer:
C, (12, -1)
Step-by-step explanation:
x - 2y = 14
x + 3y =9
Add 2y to both sides
x = 14 +2y
Substitute this into the second equation and solve
14 + 2y + 3y = 9
5y = 9 - 14 = -5
5y = -5
y = - 1
(you don't need to do this step because there is only one equation with y=-1, but just in case...)
Plug y into the first equation:
x - 2(-1) = 14
x - (-2)= x+2
x + 2 =14
x =12
Therefore, the answer is (12, -1)
The answer is C
Answer:
B) 4 miles
Step-by-step explanation:
the big triangle CAB and small triangle CED are simular (given)
this means the ratio between their corresponding sides will be the same.
find corresponding sides with alternate interior angle theorem
m CDE= m CBA
vertical angles theorem
m ACB = m DCE
therefore, AC corresponds to CE
find ratio of sides
7 miles = 36960 feet
36960/ corresponding side 21 ft
36960/ 21= 1780 ft
multiply by 1780 to get from small side to big side
small side CE = 12 ft
12*1780
=21120 ft =AC (in ft)
convert to miles (ft to miles is ft/5280)
21120/5280
=4 miles
hope this helps
