Step-by-step explanation:
R = 3x + 9y
When y = 6 and R = 7
7 = 3x + 9.6
7 = 3x + 54
7 - 54 = 3x
-47 = 3x
x = -47/3
7 2/5 is a mixed number for 37/5.
<h2>Question:- Area of the given diagram</h2>
<h2>Answer :- </h2>
Divide the diagram as shown in attachment.
Now first calculate the area of the rectangle having side 1 and 12
So area = length ×breadth
Area = 1× 12 = 12 unit²
Now find the Area of the remaining triangle with sides 12,13,5 units
So

Now put the value as -> base= 5 and height= 12

Now add both areas for your answer

Both number have filled circle meaning that t does contain -3 and 4.
t > equal to -3
t < equal to 4
Answer: B
First, find the slope between the two points.
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation.
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case.
y= 1/3x or in other words y= x/3
