Yolanda bought 12 pounds of rice for $5 . How many pounds of rice did she get per dollar?

defon

<h3>Answer: 2.4 pounds per dollar</h3>

Explanation:

We can set up the ratio

12 pounds : 5 dollars

Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"

12/5 = 2.4
5/5 = 1

The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar

The cooler measurement should be measured in cm cubed, because you are finding the volume, which is three dimensional. The volume of the figure is 180 cm cubed. If you multiply the width, length, and height of the top object you get 36. When you add that to the volume of the bottom one (144) you get 180 cm cubed.

Find an equation (in term of x) of line through the points (-1,3) and (1,4)

Serjik [45]

ANSWER

The equation is
$2y - x = 7$

EXPLANATION

The equation of the line that passes through the point (-1,3) and (1,4) can be found using the formula,

$y-y_1=m(x-x_1)$

where

$m = \frac{4 - 3}{1 - - 1}$

$m = \frac{1}{2}$
is the slope and

$(x_1,y_1)$
is a point on the line.

The equation of the line becomes,

$y - 4 = \frac{1}{2} (x - 1)$

Multiply through by 2 to get,.

$2y - 8 = x - 1$

Or

$2y - x = 7$

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x)=x^2 to the number of x-intercepts in

Ahat [919]

The graph of g(x) = -x^2 is a reflection in the x-axis of the graph of f(x) = x^2. Both graphs have one x-intercept as both graphs have their vertices at the origin, (0,0).
