Answer:
x > -24
Step-by-step explanation:
18 - 3x < 90
Subtract 18 from both sides.
-3x < 72
Divide both sides by -3. (When diving by a negative, flip the sign.)
x > -24

Answer:
10 + x/6
Step-by-step explanation:
With problems like these, you always want to break them down into phrases.
The sum of ten and the quotient of a number x and 6.
"The sum of ten" ... If you want to translate this into mathematical symbols, how would you do it? Well, if it's a sum, we know we're adding. So it's 10 plus something. So far we have:
10 +
Next: "the quotient of a number x and 6." ... How do you put this one into mathematical terms/symbols? A quotient means division. If you want the quotient of a number and six, it would be x/6. So now we have:
10 + x/6
Answer:
Option B) minimum value at −10
Step-by-step explanation:
we have
This function represent a vertical parabola open upward (because the leading coefficient is positive)
The vertex represent a minimum
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Divide the coefficient of term x by 2
10/2=5
squared the term and add to the right side of equation
Remember to balance the equation by adding the same constants to the other side
rewrite as perfect squares
----> function in vertex form
The vertex of the quadratic function is the point (5,-10)
therefore
The minimum value of the function is -10
