Answer:
$233.75
Step-by-step explanation:
2.75 x 15 = 41.25
275 - 41.25 = $233.75
Answer: 
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:

m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line
has:

If both lines are parallel, then their slopes are equal. So the slope of the other line is:

To find "b", substitute the given point and the slope into
and solve for "b":

Then the equation of this line is:

Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25
in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10
Answer:
the first one?
Step-by-step explanation:
he went up 9 floors so you'd add 9 and down 7 floors so you'd subtract
