We know that if f(a)=b then
and
if
then f(b)=a
so
since
therefor, f(-2)=0
we have 2 points, (-2,0) and (0,3)
we can use slope intercept form
y=mx+b
m=slope
b=y intercept
we have when x=0, y=3, that is the y intercept
y=mx+3
substitute the other point
(-2,0)
x=-2, y=0
0=-2m+3
-3=-2m
divide both sides by -2
the equation is
or
3x-2y=-6 in standard form

Answer:
8
Step-by-step explanation:
-4-(-12)
If you take away a negative that means you are adding so you do -4+12 because there is a double negative.
10in would be the appropriate scale factor for the drawing. 2000 is 10x200. If each inch represents 200 feet, then you would need 10 to reach the desired scale factor of the original building
The quotient of the given fraction 45/9 is 5.

What is division?</h3>
- The division is one of the four basic operations of arithmetic, which are the methods by which numbers are combined to form new numbers.
- Addition, subtraction, and multiplication are the other operations.
- At the most basic level, the division of two natural numbers is the process of calculating the number of times one number is contained within another.
Quotient:
- A quotient is a quantity produced by the division of two numbers in arithmetic.
- The quotient is widely used in mathematics and is also known as the integer part of a division, a fraction, or a ratio.
So, the quotient of 45/9 is 5 as:
45 ÷ 9 = 5
(Refer to the picture given below for working)
Therefore, the quotient of the given fraction is 5.
