Step-by-step explanation:
The slope of tangent line at a max or a minimum is 0,.
So using point slope formula.
Is the equation of a tangent line. This means we have a horizontal line at y= 4. Horizontal lines have a slope of 0.

Answer:
Step-by-step explanation:
Given.
(4x)/7 - 6 = -20
The x variable should be isolated on one side of the equation.
<u>Adding 6 to both sides of the equation.</u>
(4x)/7 - 6 + 6 = - 20 + 6
(4x)/7 = - 14
<u>Multiplying both sides of the equation by 7.</u>
(4x)/7 × (7) = - 14 × (7)
4x = - 98
<u>Dividing both sides of the equation by 4.</u>
(4x)/4 = - 98/4
x = - 24.5

Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 3)² + (y - 7)² = 2 ← is in standard form
with centre = (h, k) = (3, 7) and r² = 2 ⇒ r =
