The correct answer is 3x+90=180

<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>

<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

Which ordered pair is a solution to the system of inequalities?<br> y&lt; 3x<br> y&lt; 5
GaryK [48]

Answer:

<h2>Any point on the purple region.</h2>

<em>Look at the picture.</em>

Step-by-step explanation:

<, > - dotted line

≤, ≥ - solid line

<, ≤ - shaded region below a line

>, ≥ - shaded region above a line

y = 3x

for x = 0 → y = 3(0) = 0 → (0, 0)

for x = 2 → y = 3(2) = 6 → (2, 6)

y < 3x - dotted line, shaded region below the line

y = 5 - it's a horizontal line passes througth points (x, 5) <em>/x - any real number/</em>

y < 5 - dotted line, shaded region below the line

One of the tables shows a proportional relationship. Graph the line representing the proportional relationship from this table i
Mkey [24]

Answer:

Table C

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 y/x=k or y=kx

Find the value of the constant of proportionality in each table

Table A

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-3 ------>k=-3/-1=3  

This table has different values of k

therefore

the table A does not represent a proportional relationship

Table B

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=3 ------>k=3/1=3  

This table has different values of k

therefore

the table B does not represent a proportional relationship

Table C

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=4 ------>k=4/2=2  

This table has the same value of k

therefore

the table C  represent a proportional relationship

Table D

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=6 ------>k=6/2=3  

This table has different values of k

therefore

the table D does not represent a proportional relationship
