![\huge\boxed{\sf \{(-2,1)\}}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20%5C%7B%28-2%2C1%29%5C%7D%7D)
Step-by-step explanation:
Given equations:
y = x + 3
y = -x - 1
By comparing the above equations, we get:
x + 3 = -x - 1
Add x to both sides
<h3>x + x + 3 = -1 </h3><h3>2x + 3 = -1</h3>
Subtract 3 to both sides
2x = -1 - 3
2x = -4
Divide 2 to both sides
x = -4/2
<h3>x = -2</h3>
Substitute x = -2 in first equation.
y = x + 3
y = -2 + 3
<h3>y = 1</h3>
So,
<h3>Solution Set = {(x,y)}={(-2,1)}</h3>

Answer:
32672.64 pounds
Step-by-step explanation:
Diameter = 10ft
Radius = d / 2 = 10 / 2 = 5ft
Density (p) = 62.4 pounds/ft³
Volume of a hemisphere = 4/3Πr³
V = 4/3 * π * 5³
V = 4/3 * 392.7
v = 523.6ft³
but density ρ = mass / volume
mass = density * volume
Mass = 62.4 * 532.6
Mass = 32672.64pounds
The weight of the water in full tank is 32672.64 pounds

Answer:
$8659
Step-by-step explanation:
Patricia's sales = $ 72,900
Her commission = 11% of $72,900
= 11/100 * 72,900 [ % means out of 100 and of means to multiply ]
= 11 * 729
= $ 8019
Her monthly salary = $640
Her monthly salary along with commission = $640 + $8019
= $8659
