Yes that is the relation of the function. When x=2 y = -3
Answer:
y-5=-3(x-10)
Step-by-step explanation:
y-y1=m(x-x1)
y-5=-3(x-10)
Answer:
y = -2x -2
x + 2y = 2
2x + y = -2 } x1
x + 2y = 2 } x2
2x + y = -2 } we eliminate 2x
2x + 4y = 4 } same signs subtract and different add respectively
-3y = -6
-3 -3
y = 2 (x , 2) we reserve
2x + (2) = -2 we take on the first equation and replace 2 on a coordinate for y
2x = -2 - 2
2x = -4
2 2
x = -2 (-2,2)
x y
Answer:
4.08 km
Step-by-step explanation:
we must know what is the speed of sound to determine the distance at which the ray originated
The speed at which the sound of lightning travels is approximately 0.340km/s
then
d = 0.340km/s*12 s= 4.08 km
Answer:
$42
Step-by-step explanation:
$8.00 : 1 pound
5 1/4 = 5.25
5.25 x 8 = $42
