1. Which statements are true? An expression for "A diver swims at 14 feet below sea level and then descends another 14 feet" is
14+ (-14). An expression for "Bailey owes $14 and then earns $14" is −14+ 14. An expression for "Gail saves $14 and then spends $14" is -14 + 14. An expression for "Max saves $14 and then spends $14" is 14+ (-14). An expression for "Sera owes $14 and then earns $14" is -14 +14.
"Max saves $14 and then spends $14" is 14+ (-14)."
This statement is true.
Max saves $14, which means he has a benefit of $14. After that, he spends $14, So which means he withdrew $14, therefore $14 was subtracted from his account.
Hence, the equation will be $14 + (-$14)
<h3>What is an Equation?</h3>
A mathematical equation is a formula that uses the equals symbol (=) to connect two expressions and express their equality.
Finding the variables' values that cause the equality to be true is the first step in solving an equation with variables.
The variables for which the equation must be solved are also known as the unknowns, and the unknowns' values that fulfill the equality are known as the equation's solutions.
Equations can be categorized as either identities or conditional equations. For each value of the variables, an identity holds true.
Only specific values of the variables make a conditional equation true.
The terms "left-hand side" and "right-hand side" refer to the expressions on each side of the equals sign. It's very common to presume that an equation's right side is zero.
The generality can be realized by deducting the right-hand side from both sides, assuming that this does not reduce it.
The lines y = 2x - 1 and y = -2x + 3 intersect at exactly one point which means this system has exactly one solution. so the system is consistent and independent
