A frozen pizza is stored in a grocery store's freezer at - 6°C. During its transport home, its temperature rises 13°C. When the

Rasek [7]

At the start pizza has -6
the temperature rises 13 during the transport, so it should have -6+13=7
because the temperature goes down 19 when pizza is put in the home freezer, the final temperature should be 7-19=-12
so b is the correct answer
if the temperature rises -> +
if the temperature goes down -> -

BRAINLEST FOR RIGHT ANSWER<br><br><br><br> 6. Which rule matches the function shown in the graph?

svetlana [45]

For this case we have a function of the form:

$y = mx + b$

Where,

m: slope of the line

b: cutting point with the y axis.

The line cuts to the y-axis at the point:

$(x, y) = (0, 0)$

Therefore, the value of b is given by:

$b = 0$

We now look for the slope of the line.

For this, we use the following equation:

$m=\frac{y2-y1}{x2-x1}$

Substituting values we have:

$m=\frac{1-0}{3-0}$

Rewriting:

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

Then, the equation of the line is:

$y=\frac{1}{3}x$

Answer:

the rule that matches the function shown in the graph is:

$y=\frac{1}{3}x$

Find the perimeter of the rectrangle with vertices at R(-2, 3), S(4, 3), T(4, -1) and U(-2, -1).

mylen [45]

I attached a photo where I graphed these vertices in order to count the length and width. After counting the number of units between R & U I got a width of 4. And then I counted the units between S & T to get a width of 6. Using the formula to calculate the perimeter of a rectangle, P = 2(l+w). The perimeter is 20.

First I added the length plus the width, 4 + 6 and got 10. Then I did 10 x 2 which is how I got a perimeter of 20.
