Answer:
See explanation
Step-by-step explanation:
A candle 6 inches high burns at a rate of 1 inch every 2 hours for 5 hours. The candles burning rate is 0.5 inch per hour).
Then
- a cnadle height after first hour is 6 - 0.5 = 5.5 inches;
- a candle height after first two hours is 5.5 - 0.5 = 5 inches;
- a candle height after first three hours is 5 - 0.5 = 4.5 inches;
- a candle height after first 4 hours is 4.5 - 0.5 = 4 inches;
- a candle height after first 5 hours is 4 - 0.5 = 3.5 inches.
The candles height h (in inches) at any time t (in hours) is modeled by

Answer:
y = -5x + 1
Step-by-step explanation:
When the equation is written in slope-intercept form, as these are, then the slope is the coefficient of x. Here, the only equation that has -5 as the coefficient of x is ...
y = -5x +1
Answer:
y=2x
Step-by-step explanation:
The line passes through the origin, so the y-intercept = 0
the slope m can be found with
m = (y2-y1)/(x2-x1) = (8-2)/(2-1) = 2
Therefore the equation of the line is
y = 2x + 0 = 2x
You can open the brackets because it is addition
x+5+2x+3
after rearranging
x+2x+5+3
=3x+8
