Assume that the bank balance started at zero. Enter the income and outgo in chronological order: $300 - $50 - $75 + $225
Find the sum. This sum will represent the amount left in the account after the $225 deposit:
$250 - $75 + $225, or
$175 + $225 = $400 The final balance will be $400.
Answer: Number 1 is 40 dollars
Step-by-step explanation:
Don't look at this comment.. I messed up the first time so, yeah.
Answer: First option.
Step-by-step explanation:
You need to remember that to factorize the given expression 
, you need to choose two numbers that when you add them you get "10" and when you multiply them you get "21".
These number are:
7 and 3
Because:
Therefore, you get that the factorization of the expression is the following:
You can observe that this factorization matches with the first option.
If rectangle ABCD, defined by the coordinates A(0, 0), B(0, -4), C(-2, -4), D(-2, 0), is dilated by a scale factor of 2, with re
notsponge [240]
Answer:
D) (-2, -4).
Step-by-step explanation:
Let 
be the center of dilation. Imagine that is the center of origin of a new Cartesian Plane. What would the coordinates of point A and A' on the new plane?
Dilating 
about the "origin" of the new plane by a factor of two will give the point 
, also on the new plane.
For coordinates of A' on the original plane,
.
As a result,
.
.
.
In other words, 
is the center of dilation.
⇒
.
