The slope is 2 at all points on f(x) since f’x is just 2
Y=1/16x^2
multiplying both sides by 16 we get:
16y=x^2
The general form of a parabola is:
(x-h)^2=4p(y-k)
thus
4p=16
p=4
The parabola opens upwrd:
Focus: (h,k-p)
(0,0-4)
=(0,-4)
Directrix: y=-4

Step-by-step explanation:
<u>Step 1: Define Equation</u>
5(x - 2) - 6 = 24
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 6 to both sides: 5(x - 2) = 30
- Divide 5 on both sides: x - 2 = 6
- Add 2 to both sides: x = 8
<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>: 5(8 - 2) - 6 = 24
- Subtract: 5(6) - 6 = 24
- Multiply: 30 - 6 = 24
- Subtract: 24 = 24
Here we see that 24 does indeed equal 24.
∴ x = 8 is the solution to the equation.
Step-by-step explanation:
4x-6≥6x-20
4x-6x≥-20+6
-2x≥-14
-2x/-2≥-14/-2
x≤7
the sign changed because we divided by negative number and hope it helped
