A. 7 miles per hour

B. 2 hours

C. 2 miles per hour

D. 7 miles

Answers

Answer 1

Answer:

The answer is A.

To find speed/rate of change, divide distance by time.

7 mi/ 1 hour= 7 mph

14 mi/2 hour= 7mph

Step-by-step explanation:

Answer: A.7 miles per hour

Step-by-step explanation:

Given: You run 7 miles in one hour and 14 miles in two hours.

We know that .. The rate of change of function= (change in distance)/(change in time)

Therefore, the rate of change of function for the given situation= (14-7)/(2-1)= (7)/(1)

Hence the rate of change of function for the given situation= 7 miles per hour.

Answer 2
The answer is A. 7 miles per hour

Answers

Answer: y=5x+4

Step-by-step explanation:

Remember this

Slope-Intercept form: y=mx+b

m is the slope (5)

b is the y-intercept (4)

So your equation is

y=5x+4

Answer:

y = 5x + 4  

Step-by-step explanation:

y - 4 = 5(x - 0)

That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -

y = 5x + 4

Calculate the sum of the first n terms of the arithmetic progression (an)
a) a, = -4; d = 2; n = 16
please help me

Answers

Answer:

n²-5n

Step-by-step explanation:

The sum of the nth term is expressed as;

Sn =n/2[2a+(n-1)d]

Given

a, = -4; d = 2; n = 16

Sn = n/2[2(-4)+(n-1)2]

Sn =n/2[-8+2n-2]

Sn = n/2[2n-10]

Hence the sum of the nth term is 2n²-10n/2

2n(n-5)/2

= n(n-5)

= n²-5n

The sum of the nth term is n²-5n
