Answer:
Yes, y = x represents a proportional relationship and the constant of proportionality is
Step-by-step explanation:
<em>The Proportional is a relationship between two quantity one of them equals the product of the other and a constant, where this constant called the constant of proportionality </em>
- If x and y are proportion, then y = k x, where k is the constant of proportionality
- The proportional relationship represented graphically by a line passing through the origin point (0, 0)
Let us solve the question
∵ y = x
→ It the same as the form of the proportional equation above
∵ is a constant
∴ y is the product of x and constant
∴ y = x represents a proportional relationship
Substitute x by 0 to find y and show it represented by a line passing through the origin
∵ x = 0
∴ y = (0) = 0
→ That means point (0, 0) lies on the line which represents the equation
∴ The line which represents this relation is passing through the origin
∴ y = x represents a proportional relationship
∵ y = kx, k is the constant of proportionality
∵ y = x
∴ k =
∴ The constant of proportionality is
Answer:
A. 50
Step-by-step explanation:
Sum of interior angles of a triangle is always =180 °
Since this is a right triangle, therefore we know that one angle of the triangle measures 90°
Therefor sum of other two angles has to be =
One angle measures = 40°
Therefore the missing angle
