Answer:

1 person ordered chicken and 5 people ordered steak

Step-by-step explanation:

Since we have equations already given, lets solve to get the answer.

First, substitution

x=6-y

Then, as per the second equation.

14(6-y) + 17y = 99

84-14y + 17y = 99

3y=99-84

3y= 15

y= 15/3

y= 5

Then

x=6-y

x=6-5

x=1

We got 1 chicken and 5 steak orders

If the slope of a line is -1/4, find x when (x,2) and (1/2,6)

Alecsey [184]

Use slope formula:
m = (y2-y1) / (x2-x1)
-1/4 = 6-2 / 1/2 - x
-1/4 = 4 / 1/2 - x
-1(1/2 - x) = 4(4)
-1/2 + x = 16

x = 16 1/2 or 33/2

5c³(5c^5 + 60c^4 + 180c^3/ 5c^3)

5c³(c² + 12c + 36)

5c³(c² + 2(c)(6) + 6²)

5c³(c + 6)² <<< the answer.
