the equation y = 1/5x represents a proportional relationship. explain how you can tell the relationship is proportional from the
Pachacha [2.7K]

Answer:

Yes, y = \frac{1}{5} x represents a proportional relationship and the constant of proportionality is \frac{1}{5}

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 = \frac{1}{5} x

→ It the same as the form of the proportional equation above

∵  \frac{1}{5}  is a constant

∴ y is the product of x and constant

∴ y =  \frac{1}{5} 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 = \frac{1}{5} (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 = \frac{1}{5} x represents a proportional relationship

∵ y = kx, k is the constant of proportionality

∵ y = \frac{1}{5} x

∴ k =  \frac{1}{5}

∴ The constant of proportionality is \frac{1}{5}

Will give brainiest In △ABC, angle bisectors
EleoNora [17]

Answer:

m\angle CAB=102\dfrac{6}{7}^{\circ}\\ \\m\angle ABC=51\dfrac{3}{7}^{\circ}\\ \\m\angle ACB=25\dfrac{5}{7}^{\circ}

Step-by-step explanation:

AK is angle A bisector, then

m\angle BAK=m\angle KAC=x^{\circ}

BL is angle B bisector, then

m\angle ABL=m\angle CBL=y^{\circ}

Consider triangle ABL. The sum of the measures of all interior angles in this triangle is 180^{\circ}, then

m\angle BAL+m\angle ALB+m\angle LBA=180^{\circ}\\ \\2x+2y+y=180\\ \\2x+3y=180

Consider triangle ABK. In this triangle,

m\angle AKB=180^{\circ}-2x^{\circ} \ [\text{Supplementary angles}]

The sum of the measures of all interior angles in this triangle is 180^{\circ}, then

m\angle BAK+m\angle AKB+m\angle KBA=180^{\circ}\\ \\x+(180-2x)+2y=180\\ \\2y-x=0

Hence,

x=2y\\ \\2(2y)+3y=180\\ \\4y+3y=180\\ \\7y=180\\ \\y=\dfrac{180}{7}=25\dfrac{5}{7}\\ \\x=\dfrac{360}{7}=51\dfrac{3}{7}

Find the measures of the triangle ABC:

m\angle CAB=2x^{\circ}=102\dfrac{6}{7}^{\circ}\\ \\m\angle ABC=2y^{\circ}=51\dfrac{3}{7}^{\circ}\\ \\m\angle ACB=180^{\circ}-102\dfrac{6}{7}^{\circ}-51\dfrac{3}{7}^{\circ}=25\dfrac{5}{7}^{\circ}
