Answer:
Verify x+y+z)=(x+y)+z for the following values of x,y,z
(i)x=3/4,y=5/6,z=-7/8(
ii)x=2/; 3,y=-5/6,z=-7/9(
iii)x=3/5,y=-6/9,z=2/10(
iv)x=; - 3/5, y = - 7/10, z = - 8/15 To Verify x+(y+z)=(x+y)+z (i)x=3/4,y=5/6,z=-7/8 LHS = 3/4 + (5/6 + (-7/8)) = (3/4) + (5/6 -7/8)= (3/4) + ((20-21)/24) = 3/4 - 1/24 =(18-1)/24 = 17/24
RHS = (3/4 + 5/6) + (-7/8)= (9 + 10)/12 - 7/8 = 19/12-7/8 = (38-21)/24 = 17/24
LHS = RHS = 17/24 (ii) * x = 2/3, y = - 5/6, z = - 7/9 LHS = 2/3 + (-5/6+ (-7/9) = 2/3 + (-5/6 - 7/9) = 2/3 + (-29/18) = 2/3 - 29/18
= 12/18 - 29/18 = -17/18
RHS = (2/3 + (-5/6))+(-7/9) = (2/3 - 5/6) - 7/9 = (-1/6) - 7/9 = -1/6 - 7/9 = -3/18 - 14/18 =
-17/18
LHS = RHS....
Hence verified..

Basic way to do this when using 10's 100's 1000's and up, count the number of zeros on the end and multiple the first regular number then add the zeros back :D
Answer:
(-4, 6)
Step-by-step explanation:
to eliminate this equation it is best you subtract them
4x + 3y = 2
-5x - 3y = 2
that gives you -x = 4
x is -4
then plug x into an equation for y
-16 + 3y = 2
3y = 18
y = 6
(-4, 6) is the answer
Answer:
Step-by-step explanation:
What you have here is the factored form of the quadratic
where a is the term representing the pull of gravity, b is the upwards vertical velocity and c is the initial height. If we FOIL that out, we get the equation in a form that is easily analyzed for velocity and initial height.
This tells us that the initial vertical velocity of the dive was 10 m/sec, and that she was 15 meters up at the time of diving.
