Answer:
please check explanation
Step-by-step explanation:
Here, we want to do a matching.
We shall be matching the given statements with the features we have on the graph
Hence we shall be looking closely at the graph to answer the questions.
The y-intercept is the point at which the graph touches the y-axis
And it was at -3 degrees celsius at the beginning of the day.
The temperature was above zero between 8am and 8pm. The matching statement is that it is increasing or decreasing interval
We can see that the graph rose from 8am before it finally comes to zero at 8pm
Positive or negative interval matches with it was getting warmer between 2am and 2pm.
While temperature was lowest at 2am, we can see a peak at 2pm.
Answer:
<em>m = 1 </em>
Step-by-step explanation:
Slope =
-4 - 1 = -5
3 - (-2) = 5
5/5 = 1
Slope is 1

Answer: A. -0.25
<em><u>Hope it helps :)</u></em>
Step-by-step explanation:
So since 0.75 and -1.25 are in parenthesis, u have to multiply them.
-1 (0.75 - 1.25) = 0.5
-3/4 - 0.5 = -0.25
So the answer is -0.25
Answer:
The number of the television sets that is model p is 12
Step-by-step explanation:
Here we have total number of television sold = 40
The model p televisions sold for $30 less than the model q televisions
That is $P = $q - $30
Therefore
Let the quantity of the model p sold be X
Let the quantity of the model q sold be X
Therefore
x + y = 40
Total cost of the television = 40 * 141 = $5640
Therefore, 120*x + 90*y = 5640
Plugging in x = 40 - y in the above equation we get
4800 - 30y = 5640 or
y = -28 and
x = 68
If we put y = 40 - x we get
30x + 3600 = 5640
If we put
120*x + 150*y = 5640.........(3)
we get
x = 12 and y = 28
Therefore, since the model p sold for $30 less than the model q, from the solution of equation (3) the number of the television sets that is model p = 12
