Answer:
A)
p1 (0,0) p2 (1,2) given from the graph
slope = (y2-y1)/ (x2-x1 )
slope (m) = 2
y = mx+ b
b =0
y = 2x
b)
x = 0
y = 5
(0,5)
C)
gradient = slope
y = 3x + b
point given (0,12)
y = 3x + 12
Answer:
(x+7)(x-7)
Step-by-step explanation:
x²-49
=x²-7²
=(x+7)(x-7)
Answer:
13-0.75w+8x
13-0.75(12)+8(1/2)
13-9+4
4+4

1 sandwich cut into 8 pieces then eats 1 pieces,
then had 7/8 lefts means that 7 pieces left, if he put each mean put 1 pieces in a plate, than he need 7 plates.
When he ate 1 piece, it means that he ate 1/8 or 1 out of 8 pieces.
he put 1/8 part of the sandwich on each plate.
10mm to cm
1mm is 0.1cm
So 10 MN is 1cm
