Step-by-step explanation:
You will have to plug this into your graphing calculator.
In y=, type 5(1/2)^x in the Y1 and type 30 in Y2.

The answer is x = -2.585
Answer:
r - 12 = 74
Step-by-step explanation:
The difference between his height with 12 would signify subtraction with 12, and that difference is 74. Meaning, his height, minus 12, would equal 74.
They are perpendicular because when you change 2x+8y=16 to slope intercept form it becomes y= -1/4x+2 and the slope (-1/4) is the negative reciprocal of 4, which is the slope for your other equation.
Please comment if you have any questions :)
She would have rented it for 9 hours because you do 81 minus 9 for the kayak charge that with equal 72 then you divide 72 by 8 for the hourly charge and that will equal 9
