arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions.
2x + y = 10
x − 3y = -2
x + 2y = 5
2x + y = 4
5x + y = 33
x = 18 − 4y
y = 13 − 2x
8x + 4y = 52
x + 3y = 5
6x − y = 11
2x + y = 10
-6x − 3y = -2
y = 10 + x
2x + 3y = 45

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

good job you smart son of a gun you are smarter that einstein. 7

b i think

step-by-step explanation:

not really sure

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
