Answer:
see below
Step-by-step explanation:
6 - (3x+10) + 4(2 - x) =15
Distribute
6 - 3x -10 +8 -4x = 15
Combine like terms
4 -7x = 15
Subtract 4 from each side
4 -7x-4 =15-4
-7x =11
Divide each side by -7
-7x/-7 = 11/-7
x = -11/7
Answer:
Step-by-step explanation:
If there are 9 marbles in total and the desired outcome is to pick a green marble then the probability is 
= 
which simplifies down to a third.
This is so easy okay just make sure if it’s true or not
25/5 = 5
and also
15/3 = 5
so
(3x+ 8)/5 = 4
3x + 8 = 20
3x = 12
x = 12/3
x = 4
answer is x = 4
Answer:
{-2,4,8}
Step-by-step explanation:
The range of a function represents all of the y-values.
In this case, you have y-values of (-2,4,-2, 8)
Since it hasn't been stated whether the function is continuous or not, we can just assume the function only has values at those points.
Thus the range is {-2,4,8}
