Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus

Where

By substituting values for x1,x2,y1 and y2; the gradient becomes




Hence, the constant of variation is $1.50
Answer:
its very blury im sooooo sorry
Step-by-step explanation:
Other number: x
one number: 5x - 2
x (5x - 2)=72
5x^2 - 2x = 72
Answer:
10x+2
Step-by-step explanation:
First we work on the paranthesis. We will times 5 and 2x to get 10x
and then we times 5 and 3/4 to get 3
So now we have 10x+3
-1.75
Next, we subtract 3
-1.75 which is 2
Lastly we look at the equation as a whole!
10x+2
Answer:
x = 12
Step-by-step explanation:
6x - 4 and 112 are same- side interior angles and sum to 180° , that is
6x - 4 + 112 = 180
6x + 108 = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
