First, recall that the equation of a line is
y = mx+b
where
m = slope
b = y-int
The key to this question is the details :
Horizontal line ---> This tells you that your slope is 0
y-int = 3.5 -----> In the equation above, b=3.5
Therefore,
y = 0x + 3.5
y = 0 + 3.5
y = 3.5
Answer:
TRUE
Step-by-step explanation:
Answer:
I believe the answer is x=7
Step-by-step explanation:
<em>3x</em> and<em> 4x-1 </em> are corresponding sides and so are <em>14</em> and <em>18</em>.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7
Answer:
Step-by-step explanation:
I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
= 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
= 30 minutes
So it will take 30 minutes to finish a 5 kilometer race.
I hope the procedure is clear to you.
