Find the point (x,y)<br>on the line y = x that is equidistant from the points (-6,2) and (10,-9)

Nezavi [6.7K]

Answer:

(14.1, 14.1)

Step-by-step explanation:

If the point (x,y) is on the line y=x, then it has coordinates (x,x).

Find the distances from this point to points (-6,2) and (10,-9):

distance from (x,x) to (-6,2): $\sqrt{(x-(-6))^2+(x-2)^2}=\sqrt{(x+6)^2+(x-2)^2}$
distance from point (x,x) to (10,-9): $\sqrt{(x-10)^2+(x-(-9))^2}=\sqrt{(x-10)^2+(x+9)^2}$

Equate these distances:

$\sqrt{(x+6)^2+(x-2)^2}=\sqrt{(x-10)^2+(x+9)^2}$

Square this equation:

$(x+6)^2+(x-2)^2=(x-10)^2+(x+9)^2\\ \\x^2+12x+36+x^2-4x+4=x^2-20x+100+x^2+18x+81\\ \\8x+40=-2x+181\\ \\8x+2x=181-40\\ \\10x=141\\ \\x=14.1$

So, the coordinates are (14.1, 14.1)

Which of the following situations can be defined using an exponential function?

Darya [45]

Answer:

D) The number of bacteria decreases by 7% each hour.

Step-by-step explanation:

Exponential functions describe situations where values do not increase at a linear or constant rate. Adding or subtracting every year or hour will result in a linear function, so A, B, and C are incorrect.
