Time = t = ?
Distance 1 = d1 = 224 miles
Distance 2 = d2 = 175 miles
speed1 = v1 = d1/t
speed2 = v2 = d2/t
Also, speed 1 = 14 + v2 (Given in the data)
OR speed 1 = 14 + d2/t
speed 1 = 14 + 175/t
224/t = 14 + 175/t
multiplying both sides (each term) by "t" we get
224 = 14t +175
OR 14t = 49
t = 3.5 hours
now, speed of 1st car = 224 miles / 3.5 hours
= 64 miles / hour
and speed of 2nd car = 175 miles / 3.5 hours
= 50 miles/ hour

Determine g(x+a)−g(x) for the following function.<br> g(x)=4x2−6x
Ilia_Sergeevich [38]

Answer:

8ax + (4a²- 6a)

Step-by-step explanation:

g(x)=4x²−6x

g(x+a)

= 4(x+a)² - 6(x+a)

= 4( x² + 2ax + a²) - 6x - 6a

= 4x² + (4)2ax + (4)a² - 6x - 6a

= 4x² + 8ax + 4a² - 6x - 6a

= 4x² + 8ax  - 6x + 4a²- 6a

= 4x² + (8a  - 6)x + (4a²- 6a)

g(x+a) - g(x)

= [4x² + (8a  - 6)x + (4a²- 6a)] - (4x²−6x)

=  4x² + (8a  - 6)x + (4a²- 6a) - 4x² + 6x

= (8a  - 6)x + (4a²- 6a) + 6x

= (8a  - 6 + 6)x + (4a²- 6a)

= 8ax + (4a²- 6a)
