Answer:
Step-by-step explanation:
P=2l+2w
28=2l+2w
2l=2w-28
l = (2w-28)/2
l =2(w-14)/2
l = w-14
1/2
1/2*1*1= 1/2
Different costs:
70+25+30+60 = 185
70+70+30+50 = 220
60+70+25+50 = 205
Least cost is $185
1. B-uford
2. C-umming
3. D-acula
4. $185
(1,-2) and (0,-5) (There are an infinite amount more)
The easiest way to find solutions is to plug in an x value. Let's try 1:
y = 3(1) - 5⇒y = 3 - 5⇒y = -2
(1,-2)
Let's try 0:
y = 3(0) - 5⇒y = 0 - 5 ⇒y = -5
(0,-5)
414
87+41=128
542-128=414
