B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
250/100 = 2.5
2.5*7 = 1.75
$1.75
Hope this helped!
Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)
do you mean devils if thats what youre saying then dust devils can kill you.
thank you i hope its okay
