Numbers which are bigger than 0 are defined as positive numbers and have a prefix of + (plus).
Numbers which are smaller than 0 are defined as negative numbers and have a prefix of - (minus).
Let say number a is equal to the expression,
Since y is negative we can change its prefix to -,
Any number (in this case 3x) multiplied by negative number will produce a negative number.
Therefore the sign or prefix of number a will be -.
Hope this helps.

Answer:
9 beads are purple
Step-by-step explanation:
we know that
To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple
so
therefore
9 beads are purple
Another way to solve the problem is convert the fraction in percentage
we have
so
If the total are 18 beads
50% is 9 beads
therefore
9 beads are purple
Answer:
Step-by-step explanation:
y=-3/2(x+2)(x-4)
=-3/2(x²-4x+2x-8)
=-3/2(x²-2x-8)
=-3/2(x²-2x)-3/2×-8
=-3/2 (x²-2x+1-1)+12
=-3/2(x-1)²+3/2+12
=-3/2(x-1)²+27/2
The new area of the given replica's base is; 6250 m²
<h3>What is the required area?</h3>
We are given;
Area of base of statue = 625 m²
Now, an artist wants to create a replica of the base of statue but in the ratio 1:10.
This means that the area will increase by a factor of 10 as 1 sq.unit of the old area will represent 10 sq. units in the new one.
Thus, new area = 625 * 10
New area of statue = 6250 m²

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1
