Answer:10x^2 -18
Step-by-step explanation:since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
Answer:True
Step-by-step explanation:
Average speed refers to the total distance covered in a specific time . it also a scalar quantity (has magnitude but no direction)
Average speed=distance / time
-Speed is in kilometers/hours or meter/seconds
-distance is in kilometers or meters
-time is in hours or seconds
Answer:
I = (2,000) (0.08) (6)
I = (160) (6)

Step-by-step explanation:
I completed the quiz :)
The type of variation between the speed and time is inverse.
The equation is r = d / t
The number of miles travelled is 102 miles.
<h3>What is the type of variation?</h3>
When the speed a person is driving at increases, the time it takes to travel would decrease. On the hand, speed a person is driving at decreases, the time it takes to travel would increase. This means that there is an inverse relationship.
The equation that represents an inverse relationship is
r = d / t
Where d is the distance
Distance = t x r
51 x 2 = 102 miles
