Number 1 and number 3 are the same because if you are purchasing three tires that is 75% off the tires you need and one of them you get free. the free one becomes the overall discount of 25% off. number 3 is the same, the one quarter represents 25% off of the purchase.
Answer:
y=(1/3)x- 4/3
Step-by-step explanation:
If two lines are perpendicular to each other, then the slopes will be the negative inverse to each other.
Example:
the negative inverse of 2 is -1/2
the slope of 
is -3
the negative inverse of -3 is 
So we have the perpendicular line be :
Since it also go through (4,0)
plug in we get 
So the equation would be
Answer:I'm sorry but I think you should explain A little more. I'm in algebra two and I'm a bit perplexed, not by the problem but what goes where
Step-by-step explanation:
Explain What the variables are and what they mean please!
Answer:
f and b
Step-by-step explanation:
if you put them in y-intercept form, both slopes are 3
In b. it's easy to see that 3x has a slope of 3.
In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and b is the coeff of y.
hence -(6/-2)=3
A Yes, because fraction 89 plus 97 divided by 2 is 93
