A,C,D

"B" is definitely not the answer because the fraction isn't negative but the decimal is negative which isn't right.

Please answer the question from the attachment.

There's a 8ft. long board and the carpenter cut off 3 1/2 and 2 1/3.

So first we need to add 3 1/2 and 2 1/3 because the carpenter cut them off the 8ft. long board.

3+2=5 because it's a whole number. 1/2+1/3= 2/6+3/6= 5/6
5 5/6

Now we subtract
8-5 5/6=
7 6/6- 5 5/6= 2 1/6ft.
2 1/6ft. is what remains of the 8ft. board.

Factor this expression completely.

Orlov [11]

Answer:

Step-by-step explanation:

5 and 7 are both common factors of 35 and 40

Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.

This leaves A and B. Looking at the equation the difference between the two are the + and -

Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer

Which equation of a line contains the points (-10,15) and (8, -3) and is parallel to y +4= -(x - 1)?

JulijaS [17]

Answer:

y= -x+5

Step-by-step explanation:

The slope of the two parallel lines is equal

so, the slope of

y=-x-3 is -1

slope=y2-y1/x2-x1=-3-15/8--10=-1

the equation of the line is

y-15= -1(x--10)

y= -x-10+15

y= -x+5
