Answer:
x = 26 2/3
y = 50
Step-by-step explanation:
you could set '2y-3x' equal to '-3x+y+50' because they are vertical angles
2y - 3x = -3x + y + 50
add 3x to each side to get:
2y = y + 50
y = 50
also, we know that (1/2y + 25) + (2y - 3x) = 180 because they form a straight line
3/2y + 25 - 3x = 180
subtract 25 from each side to get:
3/2y - 3x = 155
substitute 50 for 'y' to get:
3/2(50) - 3x = 155
75 - 3x = 155
-3x = 80
x = 26 2/3
Answer:
Step-by-step explanation:
<u>Use two points on the graph to get an equation:</u>
<u>The slope</u>: m = (60 - 8)/6 = 8.667
<u>The y- intercept</u> is 8
<u>The equation of the line of best fit:</u>
Answer:
I'm not for sure but I think it's a
Answer:
45 mph
Step-by-step explanation:
It took the car 4 hours to travel 180 miles
Then
It took the car 4/4 hours to travel 180/4 miles
Since 4/4 = 1 and 180/4 = 45
Then
It took the car 1 hours to travel 45 miles
Therefore ,the car was it going at 45 mph
Answer:
The y-intercept on the y-axis
Step-by-step explanation:
The y-intercept is where you start graphing. That's why it's important to find that first.
Hope this helps!!
