She should have subtracted 6x from both sides to get -10x+11=1
Answer:
The expression is (---- + 2x)³
Step-by-step explanation:
To represents a verbal expression as an algebraic expression, we must use mathematics symbol and variables (name the unknowns quantity by letters)
The verbal expression is:
<em>Cube of more than two times a number</em>
→ Give a name for the number, assume that it is x
→ More than means (+)
→ Two times means multiply the number by 2 (x × 2)
→ The cube means power 3 for (---- more than 2x)
∴ The expression is (---- + 2x)³
<em>If the missing is 5, the statement will be The cube of 5 more than two times a number.</em>
∴ The expression is (5 + 2x)³
→ You can choose any number of the missing part
The answer should be D. You’re end equation should be y=-1/3X+3 and to get that from D you should first subtract X which gives you 3y=-X+9 and then divide negative 3 to -X and 9 and you get the answer!
