Answer:
<u>{2, 4, 6, 8}</u>
Step-by-step explanation:
The domain refers to all the possible x values of a function.
Our ordered pairs :
As they are in the form (x, y), the domain is :
⇒ <u>{2, 4, 6, 8}</u>
You would have to find the surface areas of each box, which would be 8*4 *2, 8*3 *2, and 4*3 *2. That *3, would be the cost, and then surface area of 2 would be 12*4 *2, 12*2 *2, and 2*4 *2. That *3 would again be the cost to make the box. That all would be A=64 + 48 + 24, or 136*3 = $408 to make box A, and box B=96 + 48 + 16 = 160*3 = $480 to make box B. Therefore, box B, or $480 - $408 = $72 more.

Answer:
a) slope intercept form: y = -5/14 x + 7/2
b) point slope form: y - 1 = 3/2(x - 4)
Step-by-step explanation:
a) Line A: (4,1) and (0, 7/2)
Slope = (1 - 7/2)/(4 - 0)
Slope = - 5/2 * 1/4
Slope = - 5/14
Equation in slope intercept form:
y = -5/14 x + 7/2
b)
(4,1) and (0, -5)
Slope = (1 + 5)/(4 - 0) = 6/4 = 3/2
Equation in point slope form:
y - 1 = 3/2(x - 4)
The time it took to mow all the lawns including the break he took was 1 3/4+1 1/5+1 1/5+3/4=
2 1/2+2 2/5= 4 9/10 which is 4 hours and 54 minutes and if he got done at 4:15pm then he started 4 hours and 54 minutes before at
C. 11:21 A.M.
