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.

MZJ and m M are base angles of isosceles trapezoid JKLM. If mZJ = 18x + 8 and m_M=11x + 15 find m2K.
maxonik [38]

The question is incomplete. Here is the complete question.

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°

Find the x-intercept of the parabola of with vertex (1,20) and the y-intercept (0,16). write your answer in this form: (x1,y1),(
svetoff [14.1K]
I assume that the parabola in this particular problem is one whose axis of symmetry is parallel to the y axis. The formula we're going to use in this case is (x-h)2=4p(y-k). We know variables h and k from the vertex (1,20) but p is not given. However, we can solve for p by substituting values x and y in the formula with the y-intercept:

(0-1)^2=4p(16-20)

Solving for p, p=-1/16.

Going back to the formula, we can finally solve for the x-intercepts. Simply fill in variables p, h and k then set y to zero:

(x-1)^2=4(-1/16)(0-20)
(x-1)^2=5
x-1=(+-)sqrt(5)
x=(+-)sqrt(5)+1

Here, we have two values of x

x=sqrt(5)+1 and
x=-sqrt(5)+1

thus, the answers are: (sqrt(5)+1,0) and (-sqrt(5)+1,0).
