X-intercept ⇒ When y = 0

(x – 3)² + (y – 4)²<span> = 24

When y = 0,
</span>(x – 3)² + (0 – 4)² = 24

(x – 3)² + 16 = 24

(x – 3)² = 8

(x - 3) = ±√8

x = √8 + 3 or x = -√8 + 3

x = (3 + 2√2) or (3- 2√2) [Radical Form]

x = 5.83 or 0.17 [Decimal Form]

Answer: (5.83, 0) and (0.17, 0)

(x-3)2+(y-4)2=24
2x-6+2y=24
2x-14+2y=24
2x=24+14-2y
2x=38-2y
x=19-y

Step-by-step explanation:

$the \: lcm \: of \: 2 \: and \: 9 \: is \: 18.so \: the \: lcd \: is \: 18 \\ \frac{11}{2} = \frac{11 \times 9}{2 \times 9} = \frac{99}{18 } \\ \frac{1}{9} = \frac{ 1\times 2 }{9 \times 2} = \frac{2}{18} \\ \frac{99}{18} > \frac{2}{18}$

Illusion [34]

Answer:

$c=6$

Step-by-step explanation:

The absolute maximum of a continuous function $f(x)$ is where $f'(x)=0$ . Therefore, we must differentiate the function and then set $x=-5$ and $f'(x)=0$ to determine the value of $c$ :
