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

Step2247 [10]

Answer:

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

This is the equation of the line in slope intercept form

where

The given equation not represent a proportional relationship, because the line not pass through the origin

In a proportional relationship the value of b (y-intercept) is equal to zero

Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations

nexus9112 [7]

Answer: option d is correct .

Step-by-step explanation:

In order to find the same attendance we set both equation equal

8x+191 = -x^2+26x+126

simplifying equation ,we get

x^2 -18x+65=0

(x-5) (x-13) = 0

x =5 or x =13

therefore on 5th day and 13th day both plays attendance is same

and it is obtained by plugging x = 5 in and x =13 in either of the equation.

for x = 5 ,

y = 8(5) +191 = 40+191 = 231

for x = 13

y = 8(13)+191

= 104+191

= 295

therefore option d is correct

CAN ANYBODY HELP ME OUT

Answer:

Correct option is

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Step-by-step explanation:

Here, we are given the line RQ, which is divided in two equal parts by a line PS which is perpendicular to RQ.

The foot S of PS is on the line RQ.

First of all, let us do a construction here.

Join the point R with P and P with Q.

Please refer to the attached image.

Now, let us consider the triangles PQS and PRS:

Side QS = RS (as given)

$\angle PSR = \angle PSQ = 90^\circ$

Side PS = PS (Common side in both the triangles)

Now, Two sides and the angle included between the two triangles are equal.

So by SAS congruence we can say that $\triangle PRS \cong \triangle PQS$

Therefore, the corresponding sides will also be equal.

RP = QP

RP is the distance between R and P.

QP is the distance between Q and P.

Hence, to prove that P is equidistant from R and Q, we have proved that:

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.
