Step-by-step explanation:
<u>Step 1: Define Equation</u>
4x - 8 = 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 8 to both sides: 4x = 24
- Divide 4 on both sides: x = 6
<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>: 4(6) - 8 = 16
- Multiply: 24 - 8 = 16
- Subtract: 16 = 16
Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.
Answer: 23x > 115
Step-by-step explanation:
And for "a number" we can use a variable for it
x (it can be any variable like a or b)
The product of 23 and a number implies multiplication
23x
For "greater than" use a greater than symbol
23x>
So the word sentence as an inequality is
23x>115

Answer:
y+6 = -5/4 (x-8) (this is point slope form)
Step-by-step explanation:
y-y1 = m (x-x1)
y- (-6) = -5/4 (x-8)
y+6 = -5/4 (x-8)
