Answer:
2x + 2y = 4 does not belong
Step-by-step explanation:
2x + y = 4 → y = -2x + 4
y = -2x + 4 → y = -2x + 4
f(x) = -2x + 4 → y = -2x + 4
2x + 2y = 4 → y = -x + 2

The area of the table should be
10 ft2. You want the length of the table to be 1 ft shorter than twice its width.
What should the dimensions of the table be?
Answer: width : 2.5 ft. and length : 4 ft.
Step-by-step explanation:
The area = W × L
[tex]10=W(2W-1)[/tex]
[tex]10=2W^{2} -W[/tex]
[tex]0 = 2W^{2}-W-10[/tex]
[tex]0=(2W-5)(W+2)[/tex]
W = 2.5 and -2
You can't use -2 so
[tex]L = 2(2.5)-1[/tex]
[tex]L = 4[/tex]

-3/4
-2/3
3/8
-1/5
Answer:
b
Step-by-step explanation:
y2-y1/x2-x1
memorize this formula so you always know slope for 2 points given.
y is the second number in parentheses.
whichever you choose as y2 or y1, the x values will match those numbers as well.
(y2-y1) = (1-5)
(x2-x1) = (2+4)
