Answer:
y=-1/2x+1
Step-by-step explanation:
We can use the points to find the slope of the line.
Equation: y₂-y₁/x₂-x₁
2-4/-2-(-6)
2-4/-2+6
-2/4
-1/2 is the slope of the line
So the equation is y=-1/2x+b
We can substitute one of the x-coordinates and the matching y-coordinate into this equation:
2=-1/2*(-2)+b
2=1+b
1=b
b=1
Therefore, the equation is y=-1/2x+1

Answer: there were 345 pieces of chocolate in the box.
Step-by-step explanation:
Let x represent the number of pieces of chocolate there in the box.
0.55 of a box of chocolate are dark chocolate. This means that the number of dark chocolate in the box is 0.55x
0.3 are milk chocolate. This means that the number of milk chocolate in the box is 0.3x
The rest are white chocolate. This means that the number of white chocolate in the box is x(1 - 0.55 - 0.3) = 0.15x
There are 138 pieces more dark chocolate than white chocolate. This means that
0.55x - 0.15x = 138
0.4x = 138
x = 138/0.4
x = 345
Answer:
2 meters
Step-by-step explanation:
The formula for finding the volume of a triangular prism is:
V = 1/2ba * h where b = base length, a = height of base and h = height of prism. In this case, we're solving for a. We know that V = 4.5, b = 1.5 and h = 3 so:
4.5 = 1/2 * 1.5 * a * 3
4.5 = 2.25a
a = 2 meters
