Answer:
Step-by-step explanation:
a. Y=50x+75
b. Y=50(7)+75
y=350+75
y=425
Yes, you will have enough if you use the 465 certificate. You will have $40 (465-425) left on the gift certificate.
Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2
Remember that the formula for the perimeter of a rectangle is:
is the width of the rectangle
is the length of the rectangle
Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is 
and another monomial is 
. In this case, these monomials would fulfill the perimeter equation of a rectangle.
Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
