Answer:

10

Step-by-step explanation:

Find the mean

9+12+10+15+15+15+10+x/8=12

divide 86+x/8=12

multiply both sides by 8

86+x=96

sub 86 from both sides

x=10

hope this helps

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = –2x^2 +6x – 1.
ki77a [65]
Hello :
<span>y = –2x² +6x – 1.
 y = -2(x²-3x)-1
y= -2( x² -2(3/2)x +(3/2)² - </span>(3/2)²)-1
y = -2((x-3/2)² -9/4))-1
y = -2(x-3/2)² +7/2
the <span>axis of symmetry is the line : x = 3/2 and vertex : (3/2 , 7/2 ) </span>

Find values of x and y??
MrMuchimi

9514 1404 393

Answer:

  • x = 80
  • y = 122

Step-by-step explanation:

The angles marked with x-expressions are complementary, so ...

  (3/4x -2) + (2/5x) = 90

  x(3/4+2/5) = 92 . . . . . . . add 2

  x(23/20) = 92 . . . . . . . . combine the fractions

  x = 92(20/23) . . . . . . . . multiply by 20/23

  x = 80

__

The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...

  y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32

  y = 122
