A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (-9, 5). What is the distance, to the nearest unit, between your house and the subway stop?

Answers

Answer 1
Answer:

Answer: 19 units

Step-by-step explanation:

Given: The subway stop is located at (7, -6) and  house is located at (-9, 5).

The distance formula to find distance between (x_1,y_1)\ and (x_2,y_2) is given by :-

d=√((x_2-x_1)^2+(y_2-y_1)^2)

Therefore, the distance between house(-9, 5) and the subway stop(7, -6) is given by :-

d=\sqrt{(7-(-9))^2+(-6-5)^2\n\n\Rightarrow\ d=√((16)^2+(-11)^2)}\n\n\Rightarrow\ d=√(256+121)\n\n\Rightarrow\ d=√(377)\n\n\Rightarrow\ d=19.4164878389\approx19\ units
Answer 2
Answer: Use the distance formula!

d = square root of (x2-x1)^2 + (y2-y1)^2

=19.4165

I will mark brainliest to the best answer!! Please please help!!Graph the system of equations to determine whether it has no solution, infinitely many solutions, or one solution:
2x-y=4
X+2y=2

A) no solution

B) one solution

C) infinitely many solutions

Answers

Answer:

  B)  one solution

Step-by-step explanation:

The ratio of x-coefficient to y-coefficient is different in the two equations, so the lines have different slopes. Two lines with different slopes will always have exactly one point of intersection. You don't need to graph the equations to know there is ...

  one solution

__

A graph is attached. As it happens, the two lines are perpendicular. The solution is (2, 0).
One solution is the answer

Answer:

Correct answer: V = 486 π ft³

Step-by-step explanation:

Given:

Diameter of the sphere d = 18 ft

d = 2 · r  where r is radius

r = d / 2 = 18 / 2 = 9 ft

r = 9 ft

V = (2/3) · r³· π

V = (2/3) · 9³ · π = (2/3) · 729 · π = 486 π ft³

V = 486 π ft³
