Average speed: distance traveled/elapsed time
= 75/30
= 2.5 meters per second.
Best of Luck!
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18
when y=1, x=-16
when y=0, x=-18
when y=2, x=-10
(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)

Maybe this will help:
calculate the mass of the sun
and then divide this. maybe you will get it next time.
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 6 → (1)
y = 3x - 2 → (2)
Since both equations express y in terms of x, equate the right sides
3x - 2 = - 5x + 6 ( add 5x to both sides )
8x - 2 = 6 ( add 2 to both sides )
8x = 8 ( divide both sides by 8 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 in (2)
y = 3(1) - 2 = 3 - 2 = 1
Solution is (1, 1 )
The commoner factor is 3
The equation would be
x-3y+4
