Is y=2x+3 a proportional relationship

Mathematics

Aleksandr [31]2 years ago

<em>Yes, and here's why.</em>

<em>When y= 2x + 3 is spread apart and broken down it can be explained like this:</em>

<em>y= Total value (It almost always represents a total)</em>

<em>2x= Slope (For example 2 plates per min where x would represent the ratio)</em>

<em>3= This is the Y intercept (Where the X and Y axis meet. It is also known as initial value)</em>

<em>So if I make this into an equation it could be shown like this:</em>

<em>y= 2x + 3 (The slope is 2x and represents how many flower pots someone makes in a minute, and the 3 represents 3 pots that were already made before the person started recording the data).</em>

<em>This is a proportional relationship because the slope will always be 2.</em>

<em>Hope this helps and have a nice day.</em>

answer:

no, it does not represent a proportional relationship because it has a y-intercept therefore it won’t go through the origin.

Fernando bought a jacket for 185 and sold it for 1 1/2 what he paid. Marisol spent 1/5 as much as Fernando on the same jacket bu
avanturin [10]

Answer:

Marisol made $138.75 on the sale of the jacket

Step-by-step explanation:

First we are told that Fernando bought a jacket for $185, and sold it for 1 1/12 what he paid.

Therefore, 1 1/2 of 185;

= 1.5 × 185 = $277.5

Therefore, Fernando sold the Jacket for $277.5

Next, we are told that:

Marisol spent 1/5 as much as Fernando on the same jacket

This means that Marisol spent 1/5 of $185 on the jacket

= 1/5 × 185 = 0.2 × 185 = $37

Therefore, Marisol spent $37 to buy the same jacket

Next, Marisol sold the jacket for 1/2 as much as Fernando. Since Fernando sold the Jacket for $277.5, Marisol sold the jacket for 1/2 of 277.5, and this is calculated as:

1/2 of 277.5 = 0.5 × 277.5 = 138.75

Therefore, Marisol made $138.75 on the sale of the jacket.
