To get it more clear let us assume that ax + by + c = 0 (b ≠ 0) be the equation of the given straight line. Therefore, the slope of the straight line ax + by + c = 0 is (- ab).
Answer: D
Step-by-step explanation: when you reflect across an axis, the axis that you are reflecting across doesn't change, the other one does. so in this case, the y axis doesn't change, but the x axis does, so we know that the y axis is being reflected.
Answer:
7
Step-by-step explanation;
Rewriting our equation with parts separated:
4+1/7+2+6/7
Solving the whole number parts:
4+2=6
Solving the fraction parts:
1/7+6/7=7/7 <em>(7/7 is a whole number) </em>But first before simplifing, reduce the fraction, 7/7=1/1. Then 1/1=1.
Combining the whole and fraction parts:
(Solving the whole number parts - 6)
(Solving fraction parts - 1)
<h2>6+1 = 7</h2>
Distance d is directly proportional to time t that he rides.
So d = kt where k is the constant of proportionality
Here k = his speed = 20 mph
So the required equation is d = 20t
