Answer:
-2b+4
Step-by-step explanation:
we are multiplying by a negative 1 in the expression.
-1(2b-4)
-2b+4
*negative multiplied by a negative makes a positive
Hope this helps!
Answer:

Step-by-step explanation:
Given
See attachment for box plot
Required
The interquartile range (IQR)
This is calculated using:

On the second attachment, I identify the positions of Q1 and Q3 respectively;


So:


<em>The interquartile range is 38</em>
The coefficient of 9(14)p is 126p
Answer:
<u>First find the slope using the formula </u>
m = (Y2 - y1)/(x2 - x1)
(x1, y1) = (0,6)
(x2, y2) = (2,10)
m = (10-6)/(2-0)
m = 4/2
m = 2
<u>Now we need the y-intercept or b</u>
y = mx + b
y = 2x + b
<u>Use one of the coordinates for x and y. It doesn't matter which you choose</u>
6 = 2(0) + b
6 = 0 + b
6 = b
<u>Now let's put it together for the equation :</u>
y = 2x + 6
The answer is complementary angles since they add up to 90 degrees.
