Why does.the equation y=3x+5 NOT represent a proportional relationship

Mathematics
1 answer:
sergiy2304 [10]3 years ago

Answer:

The equation not represent a proportional relationship because the line don't passes through the origin

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

so

In this problem we have

y=3x+5

This is the equation of the line in slope intercept form

where

the slope is m=5

the y-intercept is b=5

Remember that in a proportional relationship the value of b must be equal to zero (because the line passes through the origin)

therefore

The equation not represent a proportional relationship because the line don't passes through the origin

Answer:

J, 6

Step-by-step explanation:

plug in the values given into the equation

x = 5 and y = 2

4(5) - (2)³/ 2

20 - 8/2

20 - 8 = 18

12/2

6

the value of \frac{4x-y^3}{y} is 6 when the values are plugged in

What are the measures of Angles a, b, and c? Show your work and explain your answers.
Lyrx [107]

Answer:

  (a, b, c) = (30°, 60°, 105°)

Step-by-step explanation:

Angle "a" and 30° are vertical angles, hence equal.

Angle "b" and angle "a" are complementary angles, so b = 90° -30° = 60°.

Angle "c" is supplementary to the one marked 75°, so is 180° -75° = 105°.

___

Angles "a" and "b" are complementary because the sum of angles in a triangle is 180° and the third angle in that triangle is 90°. Then ...

  a+b = 180°-90° = 90°

___

75° and "c" are supplementary, because they are linear angles. The angle measure of a line is 180°, so that is their total measure.
