Answer:
D. Quadrant IV
Step-by-step explanation:
Directed numbers are numbers with either a positive sign or a negative sign. These numbers can be located easily on the number line. Examples are: 2, 5, -1, -3, -7, 9 etc.
Given that: x > 0 and y < 0
For example, let us consider specific directed number for x and y. Let x = 5 and y = -2, so that; (5, -2). This point can be located in the fourth quadrant of a Cartesian plane.
Therefore considering a Cartesian plane, the quadrant in which (x, y) could be located is: Quadrant IV.
√10 · √6 = √(10 · 6) =
= √60 = √(4 · 15) = √(2² · 15) = 2√15
Step-by-step explanation:
$4 per week from washing car
$2 per week for bathing dog
$1.5 four times a week for dishwasher -> 6 dollars total
4+2+6 = 12$
Money earned = 12*weeks
If y is substitute into either of the original equation. The solution as an ordered pair are: x=-2; y=3.
<h3>The solution as an ordered pair</h3>
x + 3y= 7 equation 1
x+2y=4 equation 2
Solving for y
x+3y-(x+2y)=7-4
x+3y-z-2y=7-4
3y-2y=7-4
y=7-4
y=3
Substitute y=3 into equation 2
x+2y=4
x+2×3=4
x+6=4
Collect like terms
x=4-6
x=-2
Therefore the solution as an ordered pair are: x=-2; y=3.
