Answer:
A function is a relation in which each possible input value leads to exactly one output value
Answer:
15
Step-by-step explanation:
let r represent red marbles then white = 2r + 5 and total is 20, thus
r + 2r + 5 = 20 ( subtract 5 from both sides )
3r = 15 ( divide both sides by 3 )
r = 5 ← number of red marbles
Thus number of white = 20 - 5 = 15
Answer:
15
Step-by-step explanation:
x = 2
-4x+8+2x+3 = ?
-4 (-2) + 8 + 2 (-2) + 3 =
= 8 + 8 - 4 + 3
= 16 - 4 + 3
= 12 + 3
= 15
