What is the value of x?<br><br> Please help! Thanks!
leonid [27]

Answer:

x=75

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

42           50

------ = ----------

42+63        50+x

42           50

------ = ----------

105          50+x

Using cross products

42(50+x) = 50*(105)

2100+42x = 5250

Subtract 2100 from each side

2100-2100+42x = 5250-2100

42x =3150

Divide by 42

42x/42 = 3150/42

x = 75

What is the axis of symmetry for f(x) = 2x2 - 8x + 8?<br> Ox<br> = -2<br> Ox=-3<br> Ox=3<br> Ox=2
zepelin [54]

Answer:

  x = 2

Step-by-step explanation:

For quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a).

Here, we have a=2, b=-8, so the axis of symmetry is ...

  x = -b/(2a) = -(-8)/(2(2)) = 8/4

  x = 2
