  • An absolute numerical number is referred to as a constant.
  • Variable: A symbol without a set value is referred to as a variable.
  • Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
  • Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

If f(x)=x^2+x and g(x)=x-3, find f(g(7)).

Answers

Answer:

A. 20

Step-by-step explanation:

  1. First we need find X.
  2. x = 7 (because we see question). f(g(7))
  3. Now we find g(x) = x - 3 => g(x) = 7 - 3
  4. Next we find f(x) = x² + x . We have f(4)
  5. f(4) = 4² + 4
  6. = 20

Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen weeds yards and Fabio walks dogs to raise money. Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog. The number of dog walks that Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed. Fabio will walk at least 25 dogs. Write a set of constraints to model the problem, with x representing the number of lawns weeded and y representing the number of dogs walked.

Answers

Answer:

12x + 9y \geq = 510\n y\leq 2x\n y \geq 25

Step-by-step explanation:

If x represents the number of lawns and 'y' represents the number of dogs that Fabio walked then:

The amount of money raised by Fabio plus the amount of money raised by Gwen must be greater than or equal to $ 510.

12x + 9y \geq = 510

The number of dogs that Fabio will walk is less than or equal to twice the number of yards of lawn cleared by Gwen.

y\leq 2x

Fabio will walk at least 25 dogs

 y \geq 25

Finally, the restrictions are:

12x + 9y \geq = 510\n y\leq 2x\n y \geq 25

Which expressions represent the distance between the two points?Choose all answers that are correct.



The number line shows two points with coordinates negative 11 and positive 7.



A.


|–11 – 7|


B.


|–11 + 7|


C.


|7 – (–11)|


D.


–11 – 7

Answers

On the number line, the distance between negative 11 and positive 7 is 18 units.

Choice A:  The absolute value of (-11 - 7) = absolute value of (-18) = 18.

Choice C:  The absolute value of [ 7 - (-11) ] = absolute value of (7+11) = 18.

'A' and 'C' are both the same number, and it's the correct answer to the question.
