Answer:
m = -1, b = -4
Step-by-step explanation:
Since the line is already in slope-intercept form, we can clearly see the slope and y-intercept. The slope is -1, and the y-intercept is -4. To graph this line, you can first plot the y-intercept, (-4,0) and then plot another point by substituting a value of x into the equation. Hope this helps!
Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours
Since adjacent angles in a parallelogram are supplementary (they add up to 180°), and ∠B is double as ∠A, you have this equation:
∠A + 2·∠A = 180°
From that you can find: 3·∠A = 180° ⇒ ∠A = 60°.
The second one, and the two last should be the right answer,
Hope this helped:)
