To find the value of ( y ) in the equation ( y = 3x - 1 ) when ( x = -3 ), substitute (-3) for ( x ):
[ y = 3(-3) - 1 = -9 - 1 = -10 ]
Thus, when ( x = -3 ), ( y ) is (-10).
Without an equality sign and not knowing the plus or minus value of 3 it can't be considered to be an equation.
A value that makes an equation "true" is known as a solution or root of the equation. When substituted into the equation, this value satisfies the equation, resulting in a true statement. For example, in the equation (x + 2 = 5), the value (x = 3) is a solution because substituting it yields a true statement: (3 + 2 = 5).
The value of x in the equation -2 x plus 3 4x-3 is 3.
An example of an equation involving absolute value is |x - 3| = 5. This equation states that the distance between x and 3 on the number line is 5 units. To solve it, we can split it into two cases: x - 3 = 5 and x - 3 = -5, leading to the solutions x = 8 and x = -2.
x = +/- sqrt(y/3)
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5

It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.

You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7

x = +/- sqrt(y/3)
Oh, what a lovely question! When x is 3, we simply substitute x with 3 in the equation to find the value of y. It's like adding a happy little tree to your painting - just plug in 3 for x and see what beautiful value of y comes out!
To find the value of ( x ) in the equation ( 3(x + 8) = 12 ), first divide both sides by 3 to isolate the expression in parentheses: [ x + 8 = 4 ] Next, subtract 8 from both sides to solve for ( x ): [ x = 4 - 8 = -4 ] Thus, the value of ( x ) is ( -4 ).
