Answer:
y = x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y-intercept )
to calculate m use the gradient formula
y = (y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 3)
m = =
the line crosses the y-axis at (0, 3) ⇒ c = 3
y = x + 3
49/7 = 7 as a whole number
The answer is 15 which is letter D
Answer:
83.33333333333333
Step-by-step explanation:
I think this is answer.
Step-by-step explanation:
Since we have given that
Time taken by steamboat makes the trip=5 hours
Time taken by yacht makes the trip =2.5 hours
Since we have also given that
the yacht is 20 knots faster than the steamboat,
So let the speed of steamboat be x
Let the speed of yacht be x+20
Now, we have given that both boats will travel the same distance ,
So,
Hence,
