Since the percent lost per hour is constant, this is a linear equation, and the slope-intercept form of a linear equation is:
Where <em>m</em> is the slope and <em>b</em> is the intercept.
In this case, we want to formulate how much percentage is left based on how many hours have passed, so the percent left is dependent upon the time passed. This means that the dependent quantity is the percent of battery life left, and this will be variable <em>y</em>.
Y = -8 because 1/2 * -4 is equivalent to -2 and then -2 minus 6 is negative 8 so your answer y=8
Answer: A and D are the correct statements.
1. In ΔBRS and ΔBDC
∠R=∠D and ∠S=∠C [∵ corresponding angles]
So by AA similarity criteria ,
△BCD is similar to △BSR.
2. As RS is parallel to DS then by basic proportionality theorem,
⇒ B is not true.
3. As we can see BC is greater than BS ,so it cannot possible.
If and
where BS=6 then .
4. As RS is parallel to DS then by basic proportionality theorem,
⇒BR×SC=RD×BS.
5. From 4 its not true that BR/RS = BS/SC.
