C and D are correct because 25 > 35 so that's C.
Its also D because they are not equal.
Hope this helps :)
Answer:
It is not a function because both (2,2) and (2,-2) have the same x-coordinate.
Step-by-step explanation:
To be a function for the same x value there should NOT be two different y values.
So, in (2, 2) and (2,-2)
For the same x value 2, there are two different y values 2, -2.
So, this is not a function.
Answer:
5 days
Step-by-step explanation:
(3 1/3 miles)/(2/3 miles/day) = (10/3)/(2/3) days = 10/2 days = 5 days
_____
time = distance / speed
Answer:
xy = -1 and y = -1/x are the same.
They are not linear equations because they are not written in the form
Ax + By = C.
Answer:
Step-by-step explanation:
ABC have sides: 5, 7 and 10
5^2 + 7^2 = 25+47 = 72 < 10^2
so triangle ABC is obtuse
JKL has sides: 12, 35 and 37
12^2 + 35^2 = 144 + 1225 = 1369 = 37^2
so triangle JKL is right-angled
PQR has sides 12, 10 and 16
12^2 + 10^2 = 144 + 100 = 244 > 16^2
so triangle PQR is acute
