For homework, anya had to find the width of a bedroom after the scale changed from 1 inch : 4 feet to 1 inch : 7 feet. her work is shown below.

what error did anya make?

(( -she set up the proportion incorrectly; the second ratio should be 2/x))

-she cross-multiplied incorrectly.

-she divided incorrectly.

-she used the wrong label; it should be inches.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

i will with my problems and all the other things that need to   be on by the way

step-by-step explanation:

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
