The solution (-4,2) satisfies for the system of linear equations 3x + 13y = 14; 6x + 11y = -2
<u>Step-by-step explanation:</u>
Step 1:
Given detail is the solution of the equations (-4, 2) ie, x= - 4 and y = 2
This implies that this solution should satisfy the given linear equations.
Step 2:
Substitute values of x and y in the equations and verify whether the right hand side equals the left hand side.
System 1 Eq(1) ⇒ LHS = 3(-4) + 13 (2) = -12 + 26 = 14 = RHS
System 1 Eq(2) ⇒ LHS = 6(-4) + 11(2) = -24 + 22 = -2 = RHS
Therefore, the first system of linear equations satisfy the condition.
A counter example disproves a statement.
The counter example for : the city of Portland is in Oregon would be : the city of Portland is in Maine.
The city named Portland can be found in both states.
Answer: see proof below
<u>Step-by-step explanation:</u>
Since (a, b) is equidistant from (-a, 2) and (2, -b), then it is the midpoint of the those two points. Use Midpoint formula to find (a, b).
3(a + b) - 4 = 0
<em>Notice that I changed the equation to "negative 4" because the equation you provided did not make a true statement.</em>

Answer:Commutative Property
Step by step explanation:
For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
The main units are inches, centimeters, meters, feet, and yards.
