The indepentent variable influences the dependent variable
the value of the depdendent variable is dependent on the value of the independent variable

y=f(x)
solve for y in terms of x

y-x-4=0
add x+4 to both sides
y=x+4
f(x)=x+4 is the answer

Can anyone give me a hint or answer this?
RideAnS [48]

Answer:

x=8.5

Step-by-step explanation:

∠AOC=68

∠COD= (2x+5)

∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.

∠AOC + ∠COD = 90

68 + (2x+5) =90

2x+5=22

2x=17

x=8.5

Find the 22nd term of the sequence 19, 13, 7,<br><br> 145<br> -107<br> 107<br> -145
olganol [36]
You subtract 6 every time. So, there are already 3 terms, so we need to find the next 19. We can do 19x6, which equals 114. Then subtract 114 from 7, which is -107.

So, the 22nd term will be -107. Hope this helps :)

jennifer bikes 7 miles south and then turns to bike 13 miles east how far away is she from where she started?
Marina CMI [18]

Answer:

She is about 14.765 miles (\sqrt{218} miles) from where she started

Step-by-step explanation:

There is a relation between the three sides of the right triangle

  • The side opposite to the right angle is called hypotenuse and it is the longest side
  • The other two sides called legs of the right angle
  • The relation between them is: (hypotenuse)² = (leg1)² + (leg2)²

∵ Jennifer bikes 7 miles south

∵ She turns to bike 13 miles east

∵ South and East are perpendicular

→ That means the distance from her start point to end point represents

   a hypotenuse of a right triangle, whose legs are 7 and 13

∴  (hypotenuse)² =  (leg1)² + (leg2)², where

  • hypotenuse is the distance between her start and end points
  • leg1 is her distance in south direction
  • leg2 is her distance in east direction

∵ Leg1 = 7 miles

∵ leg 2 = 13 miles

∴ (hypotenuse)² =  (7)² + (13)²

∴ (hypotenuse)² = 49 + 169

∴ (hypotenuse)² = 218

→ Take √  for both sides

∴ hypotenuse = \sqrt{218}

∴ hypotenuse ≅ 14.76482306

∴ She is about 14.765 miles (\sqrt{218} miles) from where she started.
