Answer:

y = 6x

Step-by-step explanation:

When x increases by 1 (from 1 to 2), y increases by 6 (from 6 to 12). So, none of the addition equations will work to express this relationship. The appropriate choice is ...

y = 6x

A test for other x-values reveals this explains all of the y-values shown.

<em>Example</em>:

x = 7, y = 6·7 = 42

Answer:

x = 70.53 degrees

Step-by-step explanation:

equation:

cos-1 = $\frac{adjacent}{hypotenuse}$

⇒ cos-1 x = $\frac{4}{12}$

⇒ cos-1 x = 0.33

⇒ x = 70.528

round to the nearest tenth:

The perimeter of a triangle is 133 inches. If one side of the triangle is five more than the shortest side, and the longest side

barxatty [35]

133=x + (x+5) + (x+14)

133 = 3x+19

3x=114

x= 114/3 =38

5+38 =43

38+14 =52

check: 38 +43 +52 = 133

3 sides are : 38, 43 & 52
