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.
Answer:
length is 8
width is 12
Step-by-step explanation:
the equation to solve this would be
x*(x+4)=96
you isolate the variable by dividing each side by factors that doesn't contain the variable
X would then equal 8
length is 8
width is 8+4= 12
It's 3.2 units
hope it's helps
Answer:
50? or together will be 90?
Answer:
11x + 12
Step-by-step explanation:
( 4x + 12 ) + 7x
Remove parentheses.
= 4x + 12 + 7x
Group like terms.
= 4x + 7x + 12
Add similar elements: 4x + 7x = 11x
= 11x + 12
