Answer:
It's linear
Step-by-step explanation:
This is a slope intercept form.
Answer:
Step-by-step explanation:
Let the length and breadth of the rectangle be a,b units respectively.
Then the area will be ab square units.
Now if the length of the rectangle is reduced by 5 units and breadth is increased by 2 units then new length and breadth will be (a−5) units and (b+2) units.
Then new area will be (a−5)(b+2).
Then according to the problem,
(a−5)(b+2)−ab=−80
or, 2a−5b=−70.......(1).
Now if length of the rectangle is increased by 10 units and breadth is decreased by 5 units then new length and breadth will be (a+10) units and (b−5) units.
Then new area will be (a+10)(b−5).
Then according to the problem,
(a+10)(b−5)−ab=50
or, 10b−5a=100
or, 2b−a=20
or, 4b−2a=40......(2).
Now adding (1) and (2) we get
−b=−30
or, b=30.
Putting the value of b in (1) we get, a=40.
Now a+b=40+30=70.
Answer: y = -(2/3)x + 5
Step-by-step explanation:
The line has negative slope. So, option 2nd and 3rd can be eliminated.
y-intercept is at y = 5 when drawing line of best fit, so option 1st can be eliminated.
Answer:
<h2>5x^2 - 11</h2>
Step-by-step explanation:
We got to add these together so
2x^2-8x-9+3x^2+8x-2
the 2x^2 and 3x^2 add to 5x^2
the 8x and -8x cancel each other out
the -9 and -2 add to -11
so..
5x^2 - 11
I hope this helped :)
