Mathematics

Sur it's a function because for each x value corresponds one and only one y value.

Another easy way to determine if y is a function is to apply the vertical test:

If you draw a vertical line and this lines intersects the graph in one point, then y is a function

Devon has 14 steel balls of equal weight. If he puts 8 of them in one pan of a balance, and the rest along with a weight of 20 g
astra-53 [7]
Let n be a number of balls: n = 14

In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20

Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>

Answer:

  • x = 5
  • y = 30
  • z = 8

Step-by-step explanation:

The rhombus has several relevant properties.

  • The sides are all the same length
  • Diagonals are perpendicular bisectors of each other
  • Diagonals divide the rhombus into congruent triangles

The last of these relations can be used to find x:

  7x° = 35°

  x = 35°/7° = 5

The second of the relations can be used to find y:

  3y° = 90°

  y = 90°/3° = 30

The first of the relations can be used to find z:

  10z -8 = 5z +32

  5z = 40 . . . . . . . . . add 8-5z

  z = 40/5 = 8
