The answer is (7/9, -5/9)
(7 over 9 and negative 5 over 9)
The speed of the car per minute is 3,520 feet (choice c). This is because in order to solve the problem, you have to convert 40 mi/h into feet. Since there are 5,280 feet per mile, you have to do 5,280 x 40, which is 211,200, which is the number of feet per hour. But, the question is asking for ft/min. There are 60 minutes in an hour, so you divide 211,200 by 60, which is 3,520. So, the speed of the car per minute is 3,520 feet.
Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.
Answer:
speed = distance / time
At 96miles in 2 hours
the speed = 96miles/ 2hours = 48miles per hour
at 5 hours, Distance = speed x time
distance = 48 x 5 = 240miles
Step-by-step explanation:
step 1 : determine the speed per hour
speed = distance / time
step 2 : after getting the speed of the car per hour, the distance cover in 5hours can now be determine using
distance = speed x time
5 miles because 2 miles then add 3 miles equals 5 miles
