The solution to the system of equations 9x - 4y = 19 and 4x + 4y = 20

is x = 3 and y = 2.

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear.

Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Two linear equations in two variables 'x' and 'y',

9x - 4y = 19 and 4x + 4y = 20.

Now, Adding these two equations we have,

13x = 39.

x = 3 and hence y = 2.

Answer:

mode: none

median: 4

mean: 4.2

Step-by-step explanation:

when dealing with mean, median, mode the first thing you should do is arrange the numbers in order from least to greatest. Once you have done so the easiest thing to do first is see which number is in the very middle, this is your median. Mode is the number that appears the most. Mean is another word for average. To find the mean, add up all the numbers then divide the sum of all the numbers by how many numbers are listed. In this case, 2+3+4+5+7=21.

21 divided by 5 (how many numbers there are) = 4.2

can someone answer my question????? pls this is already missing i’ll give brainlist and points don’t ignore

Answers

Reminder: y = mx + b, to isolate y, you would need to subtract mx value, and what you do to one side, you do to all. If there’s a coefficient in front of your y value, you then divide the equation by that coefficient. Once y is isolated, m and b values are easier to find.

Answer:

1) y = -2x + 1 // m = -2, b = 1

2) y = 5/8x - 1 // m = 5/8, b = -1

3) y = 7/8x - 3/4 // m = 7/8, b = -3/4

4) y = 3/4x + 4 // m = 3/4, b = 4
