Answer:
[see below]
Step-by-step explanation:
Quadrant One has a positive value for both x and y. (+ , +)
Quadrant Two has a negative x value. (- , +)
Quadrant Three has a negative value for both x and y. (- , -)
Quadrant Four has a negative y value. (+, -)
Therefore:
(2, -3) would be plotted in Q4. It does not lie on any axis.
(0, 8) would be on the positive y-axis. (0 is neither negative nor positive.)
(-1, -2) would be plotted in Q3. It does not lie on any axis.
(4, 7) would be plotted in Q1. It does not lie on any axis.
Answer:
44/100 will be reduced to 11/25
Step-by-step explanation:
Answer:
(-2, 3) = domain -2 = range 3
(3, -2) = domain 3 = range -2
(1, 3), = domain 1 = range 3
(0, -2) = domain 0 = range -2

Answer: Profit of $3,750
Step-by-step explanation:
Sold half of the sets at a profit of 25%;
= (15,000 * 5 sets) * 25%
= $18,750
Sold the other half at a loss of 20%;
= (15,000 * 5) * 20%
= $15,000
Profit (loss) = 18,750 - 15,000
= $3,750
The negative solution is x = –1.
Solution:
Let the number be x.
Square of a number = x²
3 times a number = 3x
Difference of square of a number and 4 = 3 times that number
Subtract 3x from both sides of the equation, we get
–3x can be written as x – 4x.
1st bracket have common term x and bracket have –4 common term.
Take common term x + 1 outside.
<em>By zero factor principle, if AB = 0 then A = 0 or B = 0.</em>
x + 1 = 0, x – 4 = 0
x = –1, x = 4
The negative solution is x = –1.
