Sue subtracted 2.9 from 20.9 and got 1.8. Explain why this is not reasonable

Answers

Answer 1

Answer: because it is way to low even looking at it u can tell that it will still be in double diets

Answer 2

Answer: -- 20.9 is roughly 30.

-- 2.9 is roughly 3.

-- If Sue started with 30 and subtracted 3 from it, she would have 27.

-- 1.8 is nowhere near 27. It's not a reasonable answer.

(Actually, 20.9 - 2.9 = 18 . So you can see where maybe she got her
digits from, but she made some kind of bad mistake in handling them.)

What is the equation of the line that passes through the points (–2, 2) and (0, 5)?

Answers

Answer:

The equation of line is given by

$y=(3)/(2)x+5$

Step-by-step explanation:

We have been given the points (–2, 2) and (0, 5) and we have to find the equation of the line.

Let us first find the slope of the line using the formula

$m=(y_2-y_1)/(x_2-x_2)$

On substituting the values, we get

$m=(5-2)/(0+2)$

$m=(3)/(2)$

Now, using the point slope form, the equation of line is given by

$y-y_1=m(x-x_1)\ny-2=(3)/(2) (x+2)\n\ny-2=(3)/(2)x+3\n\ny=(3)/(2)x+5$

Therefore, the equation of line is given by

$y=(3)/(2)x+5$

Hello,

The slope= (5-2)/(0+2)=3/2

Equation is y-2=3/2(x+2) or y=3x/2+5
