D = 5x - 3y <=ANSWER

8x + 4y - (3x + 7y) = 5x - 3y 
13x + y - (8x + 4y) = 5x - 3y 
18x - 2y - (13x + y) = 5x - 3y

Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the

irga5000 [103]

Hello,

Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3

Proof: a+b+c=15.9+5.3+31.8=53

The second number is 5.3

Use function notation to represent the average speed of the car on the interval from t = 2 to t = 7 .

Afina-wow [57]

Answer:

$Average\ Speed = \frac{s(7) - s(2)}{5}$

Step-by-step explanation:

Given

t = 2 to 7

Required

Find the average speed over these intervals

The function is not given; so, I'll represent the function as s(t)

When $t = 2;$

$s(t)= s(2)$

When $t = 7$

$s(t) = s(7)$

$Average\ Speed = \frac{Change\ in\ Distance}{Change\ in\ Time}$

This gives:

$Average\ Speed = \frac{s(7) - s(2)}{7 - 2}$

$Average\ Speed = \frac{s(7) - s(2)}{5}$
