The distance would be 17.
all you need to do is plug the points into the distance formula.
Answer:
y = 2(x-3)^2 - 2
Step-by-step explanation:
y = 2x^2 - 12x + 16
y = 2(x^2 - 6x + 8)
y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket
y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)
y = 2(x-3)^2 - 2
Answer:
x=1 and x=-1/3
Step-by-step explanation:
Therefore, x=1 and x=-1/3
Answer: so first you want to do 3.5 x the 2.5 and you get 8.75, then do 3.5 x X and you get 3.5x. now the equation is 8.75 +3.5x=14. take 8.75 nnd subtract it from itself and 14 then you are left with 3.5x=5.25. divide 5.25 by 3.5x and you get 1.5. so the answer is x=1.5
Step-by-step explanation:
Let x and y be the 2 integers.
Then x = 4y - 2
and xy = 90
Substitute for x in the second equation:-
(4y - 2)y = 90
4y^2 - 2y - 90 = 0
2y^2 - y - 45 = 0
(2y + 9)(y - 5) = 0
so y = 5 ( as it is an integer)
and x = = 90/5 = 18
Answer:- The 2 integers are 5 and 18.
