The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
He can complete about 6 pages of math homework.
you first do 200 divided by 32 and you get 6.25. So therefore Dan can complete 6 pages in 200 minutes.
Answer:
9x -2
Step-by-step explanation:
(7x + 3) + (4x - 1) - (2x + 4)
Distribute the minus sign
(7x + 3) + (4x - 1) - 2x - 4
Combine like terms
7x+4x-2x +3 -1-4
9x -2
Answer:
x^7-14x^6+84x^5-280x^4+560x^3-672x^2+448x^2-128
Step-by-step explanation:
ends are x^7 and 120^7, and use the therom in the middle
In inverese, when x increases, y deceases, when x decreases, y increses
we see that x increases for all choices
therefor the y values of the answer should be decreasing
first one is increasing, wrong
second is decreasing
third is also decreasing
fourth is increasing
look at second and third
remember
xy=k for inverse
so just solve for k for each and see if it is valid
second
1,60
(1)(60)=k
60=k
2,30
(2)(30)=60
60=60
true
therefor this is nswer
2nd option is answer
