Answer:
The answer is D. Multiply the previous value by 3.
Step-by-step explanation:
Tell whether each question can be written in the form y = mx + b
y = 8 - x^2 NO
y = 4 + x YES
y = 3 - 2x YES
Answer:
The equation of the line in slope-intercept form is:
Step-by-step explanation:
Given the points
Finding the slope




We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept



now substituting m = -10/7 and b = -45/7 in the slope-intercept form



Thus, the equation of the line in slope-intercept form is:
Answer:
1200 miles.
Step-by-step explanation:
Let d represent one way distance.
We have been given that a plane averaged 800 mph on a trip going east, but only 400 mph on the return trip.
The time taken while going east would be
.
The time taken while returning back would be
.
Since the total flying time in both directions was 4.5 hr, so we will equate sum of both times with 4.5 as:

Make a common denominator:







Therefore, the one-way distance was 1200 miles.
Step-by-step explanation:
It's 22,5 miles
