Answer: 17-3.99a
Step-by-step explanation:
Remove parentheses.
17- 0.07a- 3.92a17−0.07a− 3.92a
Collect like terms.
17+(−0.07a−3.92a)
Simplify.
17−3.99a
Answer:
4
Step-by-step explanation:
t = d/r
t = 280/70
t = 4 hours
Answer:
y = 3x -2
Step-by-step explanation:
If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.
You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.
y = m*x + b
7 = 3*3 + b
7 = 9 + b
-2 = b
y = 3x -2

Answer: Choice B
They traveled 250 miles in 4 hours. Their speed was 62.5 mph.
=============================================================
Explanation:
Start at point X. Draw a horizontal line straight across until you reach the y axis. You should arrive at y = 250. This tells us that they traveled 250 miles.
Go back to point X. Draw a vertical line until you reach the x axis. You should reach x = 4. This indicates 4 hours.
Pairing up the two values together means they traveled 250 miles in 4 hours. Divide the distance over time to get the speed
speed = distance/time = 250/4 = 62.5 miles per hour
--------
Side note: unfortunately your teacher chose the label uppercase X for the point, which may be a bit confusing since it could clash with the lowercase x along the horizontal axis.
Another note: the speed represents the slope of the line
