Answer:
20%
Step-by-step explanation:
Calculate percentage change
from V1 = 15 to V2 = 18
(V2−V1)|V1|×100
=(18−15)|15|×100
=315×100
=0.2×100
=20%change
=20%increase

Step-by-step explanation:
3 hours and 45 minutes = 3
Speed = 80 km per hour.
80 × 3 = 240 km
80 ×
= 60
240 + 60 = 300
Answer:
y =-2x+5.
Step-by-step explanation:
lines that are parallel have the same slopes. Let us plug in our slope and given point into the slope-intercept form y = mx + b. Remember, (1, 3) = (x, y)
3 = (-2) × 1 + b. Let us solve for b ,the y-intercept.
3 = -2 + b.
b = 2 + 3
b = 5.
Thus, the equation would be
y = -2x + 5
