Solve each system of equations using substitution. x×y=5 4+y=-x

valina [46]

Answer:

Step-by-step explanation:

$\left \{ {{xy=5} \atop {4+y=-x}} \right.\\\\ \left \{ {{xy=5} \atop {x=-4-y}} \right.\\\\=> \left \{ {{(-4-y)y=5} \atop {x=-4-y}} \right. \\\\ \left \{ {{-y^{2}-4y =5} \atop {x=-4-y}} \right. \\\\ \left \{ {{y^{2}+4y+5 =0} \atop {x=-4-y}} \right.$

because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R

=> y² + 4y + 5 = 0 is unreasonable

=> no solutions

Large truck has 150 gallons of gasoline that is 2/3 full. How many gallons of gas will it take to fill the tank to it's capacity

Reika [66]

2/3 of the entire tank = 150 gallons

2/3x = 150
x = 150 / (2/3)
x = 150 * 3/2
x = 450/2
x = 225 <== the entire tank can hold 225 gallons
