Answer:
x+20 ≤ x²+9
Step-by-step explanation:
the options you gave didnt have any square options, so imma just guess you meant this? if not, let me know.
To be a function every x should have only one y-value.
<span>a. (0,0), (1,1), (2,2), (3,3), (4,4) - We do not see repeating values of x, so it is a function
</span>b. (0,8), (1,6), (2,4), (3,2), (4,0)- We do not see repeating values of x, so it is a function
<span>c. (3,0), (3,1), (3,2), (3,3), (3,4) - We see repeating value of x, that means that one value of x corresponds many values of y , so it is not a function.</span>
62500 - 56100 = 6400 - number of retrivers u lost per year.
Answer need to be lower then 62,5 and 56,1 thousand so no (A) and not (D)
Number is reduce by 6400 and starting amount was 62500, 2 zeros and end must stay there in answer so not (B)
Then it must be (C)
Or u can calculate 62500 - 9*6400 = 4900
Answer:
(3/5)x+1/4=(3/4)x-2/5
<=> (3/5)x - (3/4)x= -2/5 - 1/4
<=> x(12/20 - 15/20) = -13/20
<=> x(-3/20) = -13/20
<=> x = 13/3
