Step-by-step explanation:

From the Pythagorean theorem we have:

a^2+b^2=c^2           <em>subtract b² from both sides</em>

a^2=c^2-b^2\to a=\sqrt{c^2-b^2}

Same:

b=\sqrt{c^2-a^2}

For f(x) = -1/5x - 14 find x when f (x) = -8
sergejj [24]

Hi!

30 = x

f(x) = -1/5x - 14 find x when f (x) = -8

Set the equation equal to -8

-8 = -1/5x - 14

Add 14 to both sides.

6 = -1/5x

Multiply both sides by -5.

30 = x

Hope this helps! :D

16h - 9 = -13 - 6h - 18<br><br> h=
densk [106]

Answer:

h = -1

Step-by-step explanation:

Solve for h:

16 h - 9 = -6 h - 31

Add 6 h to both sides:

16 h + 6 h - 9 = (6 h - 6 h) - 31

6 h - 6 h = 0:

16 h + 6 h - 9 = -31

16 h + 6 h = 22 h:

22 h - 9 = -31

Add 9 to both sides:

22 h + (9 - 9) = 9 - 31

9 - 9 = 0:

22 h = 9 - 31

9 - 31 = -22:

22 h = -22

Divide both sides of 22 h = -22 by 22:

(22 h)/22 = (-22)/22

22/22 = 1:

h = (-22)/22

The gcd of -22 and 22 is 22, so (-22)/22 = (22 (-1))/(22×1) = 22/22×-1 = -1:

Answer:  h = -1

What is the answer of 12-(-5) ? adding integers

Notice that the two minus signs cancel out, so 12-(-5) is equivalent to 12+5.  This sum is clearly 17.
