Answer: The answer would be 1/2
Step-by-step explanation:
<em>Y varies DIRECTLY as x. Find the constant of variation, k, if y = -5x </em>
<em>The first sentence is there for information, the constant is a number( 1,2,3...so on) , so the only number is -5 </em>
<em>It is a linear equation meaning equation of a straight line. </em>
<em>its form is y= mx+b, where m is the slope of the line, b is the y intercept when x=0. these info you have to memorize like your life depend on it. </em>
<em>next, y varies directly as x. If y = 15 when x = 60, find y when x = 100 </em>
<em>if y= 15, when x=60, then there is a number m such that m*y= 60 </em>
<em>or m= 60/y= 60/15 =4 </em>
<em>so the equation is y=4x. in this cause, the b=0 </em>
<em>so when x=0, y=0 </em>
<em>The distance a car travels at a constant speed varies directly as the time the car spends traveling. If a car traveled 105 miles in 3 hours, how far could the car travel in 5 hours? </em>
<em>remember that distance = speed times time. </em>
<em>or d=Vt </em>
<em>so car goes 105 miles on 3 hours </em>
<em>how far it goes in one hour? </em>
<em>if you know that, then you can tell how far it goes in 5 hours.</em>
