Add -15c and 7c since they have the same variable. After that you get a negative answer so you add the answer to both sides. That will cancel both numbers so it will be 1=3, the answer will be false.

Add like terms
-15c+7c=7c-15c=-8c
we can't add the c terms and the numbers so we leave it so
-8c+1=3-8c
add 8c to both sides
8c-8c+1=3+8c-8c
0+1=3+0
1=3
false
there is no solution

Answer: 16) $\bold{\sqrt{x}}$ (17) $\bold{\dfrac{x-4}{2}}$ (18) $\bold{\sqrt{x}-2}$ (19) 3x - 18

Step-by-step explanation:

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

$\bold{\sqrt{x} =y}$

17) Given: y = 2x + 4

Swapped: x = 2y + 4

x - 4 = 2y

$\bold{\dfrac{x-4}{2}=y}$

18) Given: y = (x + 2)²

Swapped: x = (y + 2)²

√x = y + 2

$\bold{\sqrt{x}-2=y}$

19) Given: $y=\dfrac{1}{3}x+6$

Swapped: $x=\dfrac{1}{3}y+6$

$x - 6 = \dfrac{1}{3}y$

3(x - 6) = y

3x - 18 = y

Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

Alexxandr [17]

Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !

To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:

√ ( 225 + 64 ) .

Solve for x in the diagram below.

xz_007 [3.2K]

Answer: 5x + (x + 54) = 6x + 54

So now 6x + 54 = 90 because u are solving a right angle.

90 - 54 is 36. So 6x = 36 and 36 divided by 6 is 6. Your answer for X = 6 Hope this helps you please mark brainliest
