Answer:
In first equation if we put the value of x and y (x=2,y=2)than,
3x+y=8
3×x+y=8
3×2+2=8
6+2=8
8=8
in second equation the value of x=2,y=1
x2+xy=6
x2+x×y=6
4+2×1=6
4+2=6
6=6
The equation y - 2 = -5(x - 2) represents a linear function ⇒ 1st answer
Step-by-step explanation:
A linear function is any function that graphs to a straight line
(not a vertical line)
The forms of the linear equation are
- y = m x + b, where m is the slope of the line which represents the function and b is the y-intercept ⇒ slope-intercept form
, where m is the slope and
is a point lies on the line which represent the function ⇒ slope-point form- Ax + By = C, where A, B, and C are constant ⇒ standard form
Linear function means the greatest power x and y in the equation of the function is 1
∵ The equation is y - 2 = -5(x - 2)
∵ The greatest power of x and y is 1
∵ The equation is in the form of
, where
m = -5 and the coordinates of the point are (2 , 2)
∴ The equation represents a linear function
The equation y - 2 = -5(x - 2) represents a linear function

The change in quantities can be represented as percentage
<em>The percentage decrease in miles driven is 34.83%</em>
The given parameters are:


The percentage decrease is calculated as:

Substitute known values




The negative sign implies that, the change represents a decrement.
Hence, the percentage decrease in miles driven is 34.83%

Answer:
Subset is part of set which is obtained from Universal set.
Step-by-step explanation:
Like for example :-
A - ( 1,2,3,4,5,6,7,8)
And B - ( 1,2 , 3)
So we can say B is subset of A.
