Use the echelon method to solve the system of two equations in two unknowns. check your answers. 5x – 3y = 1 8x - y = 13 select the correct choice below and fill in any answer boxes within your choice. o a. the solution of the system is . (simplify your answer. type an ordered pair) ob. there are infinitely many solutions. the solution is ( o c. there is no solution y), where y is any real number

x = 2, y = 3

Step-by-step explanation:

Given equations,

5x - 3y = 1,

8x - y = 13

Augmented matrix,

↔

Also,

Hence, the solution of the given system would be,

x = 2, y = 3

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
