A. There is a positive correlation between the temperature and the amount of ice cream sold. This means that as the temperature increases the amount of ice cream also increases.

B. For the best fit you must calculate the slope between two points that are more-or-less representative of the entire graph. In this case it seems to have already done this with certain points so if you take the points (15,35) and (0,5) you can calculate the slope between these two points which is m=(35-5)/(15-0)=30/15=2. So the best fit slope for this particular case would be two and you would just draw a line through the graph at approximately the middle of the dots to best represent all of the data.

and the y-intercept is 5 so the approximate equation for the graph would be y=2x+5

Answer:

C) (-6,0)(2,0)

For x-intercept, f(x) = 0:

${ \tt{ {x}^{2} + 4x - 12 = 0 }} \\ { \tt{(x - 2)(x + 6) = 0}}$

What two number that are the same have the product of 0.2 and the quotient of 0.8

Pie

Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>

Use long division to find the quotient below. (2x^3+x2+25)/(2x+5)

Contact [7]

Answer:

x^2 -2x +5

Step-by-step explanation:

x^2 -2x +5

----------------------------------------------------------

2x + 5 / 2x^3 + x^2 + 0x + 25

-(2x^3 + 5x^2)

----------------------------

-4x^2 + 0x

-( -4x^2 - 10x )

-----------------------------------------

10x + 25

-(10x + 25)

---------------------------

The desired quotient is x^2 -2x +5
