3.5 is the constant. A constant is a term that only consists of a number and doesn't have any variable next to it, basically a number that stands by itself. In this case 3.5 is the only constant, lone number, in the equation, so 3.5 would be the answer.

Answer:
Fourth option
Step-by-step explanation:
The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.
Hope this helps.
The X-intercept is a point where the line crosses the X lines. That means it would be the point where Y=0. Then to find the X-intercept you only need to insert Y=0 into the equation. The calculation would be:
<span> 4×+2y=12
4X+ 2 (0)= 12
4X =12
X=12/4 = 3</span>
