Answer:
3.945
Step-by-step explanation:
Okay so subtract 50 from both sides and you would get 360=90x and then divide each side by 90 and you would get x= 4 so it took 4 hours
Answer:
C) P(1, -26/7)
Step-by-step explanation:
You want the weighted average of A(-4, 2) and B(3,-6) using weights 2 and 5, respectively.
<h3>Weighted average</h3>
Each of the values is multiplied by the corresponding weight, and the sum of those products is divided by the total of the weights to obtain the weighted average.
P = (2A +5B)/(2+5)
P = (2(-4, 2) +5(3, -6))/7 = (-8 +15, 4 -30)/7 = (7, -26)/7
P = (1, -26/7)
The coordinates of P are (1, -26/7).
In the slope intercept formula (y = mx + b)
the m = slope
the b = y intercept
hope this helps :)
you have to rearrange the equation to match the formula
so.....
-y = 6x - 6
m = 6x/-y = -6 (you can just see it as 6/-1 you dont have to count the x and y)
b = -6
