No. The line just has to go below ' 1 '.
Money : price = quantity
1) 3 : 0.5 = 6 Kg
2) 3 : 1 = 3 Kg
3) 3 : 1.5 = 2 Kg
4) 3 : 2 = 1.5 Kg
5) 3 : 3 = 1 Kg
Answer:
An optical prism is a transparent optical element with flat, polished surfaces that refract light. ... A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow).
Step-by-step explanation:
The histogram depicts that the number shipments that had more than 20 light bulbs broken is D. 12.
<h3>What is a histogram?</h3>
A histogram simply means a graphical representation that is used to organize a group of data points into ranges.
From the complete question, the histogram shows that the number shipments that had more than 20 light bulbs broken is 12. This can be interpreted based on the ranges shown in the histogram.

The solutions to the given system of equations is (0, -6) and (1, -5)
<h3>Simultaneous equations</h3>
From the question, we are to determine the solutions to the given system of equations
The equations are
x − y = 6 --------- (1)
y = x² −6 ---------- (2)
From equation (1)
x - y = 6
∴ x = 6 + y ------- (3)
Substitute into equation (2)
y = x² −6
y = (6+y)² −6
y = (6+y)(6+y) -6
y = 36 + 6y + 6y +y² -6
y = 36 + 12y + y² - 6
Simplifying
y² + 12y - y + 30 = 0
y² + 11y + 30 = 0
Solve quadratically
y² + 11y + 30 = 0
y² + 6y + 5y + 30 = 0
y(y +6) +5 (y +6) = 0
(y + 5)(y + 6) = 0
y + 5 = 0 OR y + 6 = 0
y = -5 OR y = -6
Substitute the values of y into equation (3)
x = 6 + y
When y = -5
x = 6 + (-5)
x = 6 -5
x = 1
When y = -6
x = 6 + (-6)
x = 6 -6
x = 0
∴ When x = 0, y = -6 and when x = 1, y = -5
Hence, the solutions to the given system of equations is (0, -6) and (1, -5)
