Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
The answer would be Undefined
Answer:
B. (10,4)
Step-by-step explanation:
Let x be the independent variable and y represents the dependent variable in the graph,
∵Graph represents the direct variation,
⇒ y ∝ x
⇒ y = kx
Where, k is the proportionality constant.
Here, k = 0.4,
⇒ Equation that shows in the graph would be,
y = 0.4x
At (4, 10),
10 = 0.4(4) ( False ),
⇒ (4, 10) is not in the graph.
At (10, 4),
4 = 0.4(10) ( True )
⇒ (10, 4) is on the graph.
At (0.04, 10),
10 = 0.4(0.04) ( false )
⇒ (0.04, 10) is not on the graph.
At (10, 0.04),
0.04 = 0.4(10) ( false )
⇒ (10, 0.04) is not on the graph.
The expression can be simplified as:
b-8
