Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions.
tatyana61 [14]

Answer: \large\boxed{\text{No Solution}}

Step-by-step explanation:

<u>Given equation</u>

\sqrt{t+1}+9=7

<u>Subtract 9 on both sides</u>

\sqrt{t+1}+9-9=7-9

\sqrt{t+1}=-2

<u>Conclusion</u>

\text{Since radical values are always positive, it is false that }\sqrt{t+1}\text{ will equal to -2}

\text{Therefore, it is }{\large\boxed{\text{No Solution}}}\text{ in the context of real numbers}

Hope this helps!! :)

Answer:

4 . The answer is no .

5 . x=1

6. unlimited answers

7. There's no answer to this question .

Step-by-step explanation:

___________________

4. solution :

-20(2-4) = 2((5×-4) -4) =

-40 = -48 × impossible

___________________

5. solution :

-3+4x+12x+24 = 28x +12-3

-3+24-12+3=28x-12x-4x

27-15=12 = 2x - 16x =12x

12 = 12x

x =1

__________________

6. solution :

24-3x+9-6 = -8x+20+5x+7

8x-5x-3x = -24-9+6+20+7

0=0

x can be every number you think because they are always equal to each other .

examination :

if you consider x as 1 :

24-3+9-6=-8+20+5+7

24=24

or if you consider x as 2 :

24-6+9-6 = -16+20+10+7

21 = 21

__________________

7 . solution :

3(x-2) = 3x+4

3x-6 = 3x+4

3x-3x = 10

0 = 10

if you consider x as 1 :

3-6 = 3+4

-3 = 7 × impossible .

Given a circle with a radius of 2, which is the length of an arc measuring 75 degrees?
WARRIOR [948]
\bf \textit{arc's length}\\\\&#10;s=\cfrac{r\theta\pi }{180}\qquad &#10;\begin{cases}&#10;\theta=\textit{angle in degrees}\\&#10;r=radius\\&#10;---------\\&#10;r=2\\&#10;\theta=75&#10;\end{cases}\implies s=\cfrac{2\cdot 75\cdot \pi }{180}
