Step-by-step explanation:

You can divide the larger number by the smaller number for all of them and see if they all match. If they dont then its not porportional.

Answer:

the answer for this question should be b because first of all remember when it is a proportional relationship it has to be showing like a pattern the same through all of it not different so first of all anaylze them and see.

A cannot be because its correct when you divide first y and then x like this example ==> 8/3 and you get this repeating number 2.66666 or 2.66 or 2.67 and when you do it for all the numbers you get the same answer.

B can be because when you divide all of them you get different answers like for example.

====> 61/10= 6.1

=====> 85/14= 6.07 rounded

======> 139/23= 6.04 rounded

======> 169/28= 6.03 rounded also

C cannot be because its correct meaning you divide y first and then x so like this example 2/1= 2 and when you do it to the other numbers that are there it would give you 2 so c cannot be its correct.

d cannot be because its correct you divide 14 and 7 and you get 2 so when you divide all of them you get 2.

check all of them first to see which option is correct and always use process of elimination so hopefully b is the correct and have a great day.

Step-by-step explanation: please give brainliest to the first people that answer it first.

Select which form to use when you know the slope of the line and one of the points on the line. a. horizontal line c. slope-inte

Cloud [144]

The form which should be used when you know the slope of a line and one of the points on the line is: d. point-slope form.

<h3>What is the point-slope form?</h3>

The point-slope form can be defined as an equation which is used when the slope of a line and one of the points on this line is known.

Mathematically, the point-slope form of a line is given by:

y - y₁ = m(x - x₁)

<u>Where:</u>

m is the slope.

x and y are the points.

In conclusion, you should use the point-slope form when you know the slope of a line and one of the points on the line is given.

Answer: the system has no solution.

Step-by-step explanation:

\displaystyle\\

\left \{ {{x^2y=16\ \ \ \ \ (1)} \atop {x^2+4y+16=0\ \ \ \ \ (2)}} \right. .\\

Multiply\ both\ sides\ of\ the\ equation\ (2)\ by\ y\ (y\neq 0):\\

x^2y+4y^2+16y=0\\

We\ substitute\ equation\ (1)\ into\ equation\ (2):\\

16+4y^2+16y=0\\

4y^2+16y+16=0\\

4*(y^2+4y+4)=0\\

4*(y^2+2*y*2+2^2)=0\\

4*(y+2)^2=0\\

Divide\ both\ sides\ of\ the \ equation\ by\ 4:\\

(y+2)^2=0\\

(y+2)*(y+2)=0\\

So,\ y+2=0\\

y=-2.\\

$\displaystyle\\We\ substitute\ the\ value\ of\ y\ into\ equation\ (1):\\x^2*(-2)=16\\Divide\ both\ sides\ of\ the \ equation\ by\ -2:\\x^2=-8\\x^2\geq 0\\ Hence,\ the\ system\ has\ no\ solution.$
