Length of a spoon (cm)
Thinkness of envelope (mm)
Hight of building (m)
Answer:
-8b^3ax^2
Step-by-step explanation:
Between -0.56 and -0.65 : -0.560000000001 and -0.649999999999
Between -5.76 and -5.77 : -5.7601 and -5.7602
Between 3.64 and 3.46 : 3.639 and 3.63900001
The slope of the line is: m=(5-0)/(-3-2)=-1
y=-x+b
find out b by using a point: 0=-2+b, b=2
so the equation of the line is y=-x+2
it is dotted, so they should be an equal sign.
the shaded part is to the right, above the line, so it is a >
the inequality is y>-x+2
5x + 3y = 7> (4) 5x + (4) 3y = (4) 7
4x + 5y = 3> (-5) 4x + (-5) 5y = (-5) 3
20y + 12y = 28
-20x -25y = -15
(X's cross out) 12y - 25y = 28 -15
-13y = 13
Y = -1
(Plug in for y) 5x + 3(-1) = 7
5x -3 =7 (add 3 to 7)
5x = 10 (divide by 5)
X= 2
Ordered Pair= (2, -1)
