Answer:
t=5.20s
Step-by-step explanation:
I think that is the expression because it say he purchases two bags, all the bags are 5.20 so he brought two bags which are school bag and one hand bag the formula I used was y=mx+b but in these case I had to put t=5.20x. I hope this really helped you..

Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept of the line. I will calculate the slope using the points (0, 3) and (1,6)
Slope = 
= 
= 3
The y-intercept, based on the graph, is 3. Thus, the equation is: y = 3x + 3.
The kinetic energy is calculated through the equation,
KE = mc²
where KE is kinetic energy, m is mass, and c is the masses. Substituting the known values,
KE = (5 kg)(3 x 10^8)²
KE = 4.5 x 10^17 J
