Answer:
Step-by-step explanation:
y -5x = 2
10x -3y =9
substitute x for 3/5 and y for -1
-1 -(5*3/5) = 2
(10*3/5) -3(-1) =9
simplify :
-1 -3 =2
6+3 =9
-4 =2 Not true
9=9 True
Conclusion: the point (3/5, -1) is not a solution to the given system of equations
So first I saw that u need 1 adult with every 6 children so I did 6*4 and got 24. From that I got 4 adults with 2 leftover children. For the other class which has 28 children, u would still need 4 adults. Now since u said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.
Answer:
The volume is 
Step-by-step explanation:
we know that
The volume of the sphere is equal to

we have
----> the radius is half the diameter

substitute the values

Answer: x
<u>Step-by-step explanation:</u>
g(x) = 4x + 10 f(x) =
to find g(f(x)), replace "x" in the g(x) equation with what f(x) equals. Another way of writing g(f(x)) for this problem is: g(
).
g(f(x)) = 4
+ 10
= x - 10 + 10
= x
The answer is 5 I’m not sure if this is correct
