Answer:
45
Step-by-step explanation:
(replace m with 7 and replace n with 3)
6 x 7 = 42 then you add 3 = 45
<span>Each piece length will be 1/8 part of the whole piece, so as the total length is 9 yards then we will have that the lengh of each piece is one and eighth yard.
The division expression is as follows:
Piece length = 9 * 1/8 = 9/8 = (8+1)/8 = 8/8+1/8 = 1 + 1/8 = 1 + 0.125 = 1.125 yards</span>
y = -1x + 2
Put the points in the slope equation to find (-1 as m, -2 as x, and 4 as y)
y = mx + b
4 = -1(-2) + b
4 = 2 + b
4 - 2 = b
2 = b
Final equation: y = -1x + 2
It would be .3 i think if you are talking about scientific notation :)
