Answer:
y=x+1
m=1
b=1
Step-by-step explanation:
-2x+2y=2
+2x +2x
2y=2+2x
divide by 2
y=1+x
rewrite
y=x+1
Since b is the y intercept, b would equal 1.
The slope of the line, or m, would be 1 as well.
Answer:
The time of a commercial airplane is 280 minutes
Step-by-step explanation:
Let
x -----> the speed of a commercial airplane
y ----> the speed of a jet plane
t -----> the time that a jet airplane takes from Vancouver to Regina
we know that
The speed is equal to divide the distance by the time
y=2x ----> equation A
<u><em>The speed of a commercial airplane is equal to</em></u>
x=1,730/(t+140) ----> equation B
<u><em>The speed of a jet airplane is equal to</em></u>
y=1,730/t -----> equation C
substitute equation B and equation C in equation A
1,730/t=2(1,730/(t+140))
Solve for t
1/t=(2/(t+140))
t+140=2t
2t-t=140
t=140 minutes
therefore
The time of a commercial airplane is
t+140=140+140=280 minutes
Remember that the degree measure of each exterior angle of a polygon can be found through the formula
where 
is the number of sides on the polygon.
Since a pentagon has five sides, the degree measures of each of its five sides would be:
Thus, our answer is Choice B, or 72 degrees.
The Median is 11, and it is shown by the line on the middle of the rectangle.
The range is 12, and you can find it by subtracting the highest data point (17) by the lowest data point (5).
The 25th percentile is 9, and it could be found by looking at the first line in the rectangle.
The 75th percentile is 14, and it could bee found by looking at the last line in the rectangle.
The inter-quartile range is 5, and it can be found by subtracting the upper quartile, or the 75th percentile (14) by the lower quartile, or the 25th percentile (9). 14-9=5
Hopefully this helps.
