Answer:

7.2

Step-by-step explanation:

14 = c

12= b

√(c² - b²)

12 x 12 = 144

14 x 14 = 196

196-144 = 52

√(52) = 7.21110255093

Answer:

x ≈ 7.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 14²

x² + 144 = 196 ( subtract 144 from both sides )

x² = 52 ( take square root of both sides )

x = \sqrt{52} ≈ 7.2 ( to the nearest tenth )

X –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3
Naddik [55]

Answer:

<u>(a) x = 2</u>

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = \frac{18}{9}

x = 2

Therefore, your answer is (a), since x = 2.

Find (g*f)(3)<br><br> f(x)= 7x + 8 <br> g(x)= -1/x
Sophie [7]

Answer:

-21-24/x

Step-by-step explanation:

f(x) is a function on his own which is f(x)=7x+8

we multiple it with another function which is g(x)=-1/x

that gives us (g*f)=-7-8/x

then multiple it by 3 we have -21-24x
