Hello,
answer D (-2,3)
Indeed
y=4x+11
y=-2x-1
==>4x+11=-2x-1
==>6x=-12
==>x=-2
And y=4*(-2)+11=3
Answer:
see below
Step-by-step explanation:
9 x 8 = (10 x 8) - ( blank x 8) =80 - blank = blank
We are replacing 9 with 10 minus something
9 = 10 -1
9 x 8 = (10 x 8) - ( 1 x 8)
80 - 8
72
-3x + 4y = -6
20x - 4y = 40
-----------------------
17x = 34
x = 2
5(2) - y = 10
10 - y = 10
y = 0
the correct answer is D. (2,0)
Each piece will be 26cm by 4cm.
Width is 26 cm.
Length is 36 cm. The problem states that the length is 10 cm longer than the width. Since width is 26 I just added 10 to arrive at 36 cm.
36 / 9 = 4 cm.
The width will still be 26 but the length is now 4 cm.
Area = length * width
Area = 4 * 26
Area = 104 cm
