Step-by-step explanation:
<u>Step 1: Define</u>
10.5x - 1.9 = 19.1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1.9 to both sides: 10.5x = 21
- Divide 10.5 on both sides: x = 2
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 10.5(2) - 1.9 = 19.1
- Multiply: 21 - 1.9 = 19.1
- Subtract: 19.1 = 19.1
Here we see that 19.1 does indeed equal 19.1.
∴ x = 2 is a solution to the equation.
Hi!
The only true answer is DX = AX.
Hope this helps!
Function notation is a way of writing equations that has a form:
f(x)=ax+b, where x is the independent variable, f(x) is the output of the function, a and b are constants.
So if we have an equation: y-x-4=0, first we leave y on the left side and put everything else on the right side:
y=x+4, then we can write it in function notation as:
f(x)=x+4, where f(x) corresponds to y.
