2.3 x 10 to the power of 1
Answer:
y = 1/5x - 5.
Step-by-step explanation:
Use point-slope form of a straight line:
y - y1 = m(x - x1)
Here m = the gradient = 1/5 and (x1, y1) = (0, -5) so we have:
y - -5 = 1/5(x - 0)
y + 5 = 1/5x
y = 1/5x - 5.
Answer:
x = 6

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.
