Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
3rd option.
at least shows that the number can be equal to 2, and also that 2 should be the smallest possible value of the number.
Plug in e for 3.
10(3+7)
Use the distributive property. a(b+c)= ab+ac
10*3= 30, 10*7=70
30+70=100
The expression equals 100.
I hope this helps!

Answer:
Given Equation: y=5x-1
as we know that the y intercept have, x coordinate(absicasse) equal to 0
so,put x=0 to get y intercept
i.e, y =5×0 -1
i.e, y= <em><u>-</u></em><em><u>1</u></em>
