Acandle that is 13 inches tall is lit. as the candle burns, its height decreases at a rate of 0.5 inches per hour. let t t represent the varying number of hours that have elapsed since the candle started burning. write an expression to represent the varying value of the quantity described in each part. each expression should be written in terms of the appropriate variable.

the answer to the question is a  

it has the same slope and the same y-intercept.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

it would rotate about 180 degrees.
