Answer:

[1]    x - 8y = 17

  [2]    -3x + 24y = -51

Step-by-step explanation:

// Solve equation [1] for the variable  x  

 

 [1]    x = 8y + 17

// Plug this in for variable  x  in equation [2]

  [2]    -3•(8y+17) + 24y = -51

  [2]    0 = 0 =>  Infinitely many solutions

-3|x|+2x-1 if x=-5<br><br> plz help
Savatey [412]

Answer:

 f(x) = -3|x| + 2x - 1

f(-5) = -3|-5| + 2*(-5) - 1

      = -3*5 + 2*(-5) - 1

      = -15 - 10 - 1

      = -26

Hope this helps!

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!
Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>
  • For Example : Let x and y be two monomials which is linear
  • If we product the two linear monomials we get
  • x\times x=x^2 which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let x^2 be the Quadratic monomial has one term with degree 2 and x^2+2x+3 be the quadratic trinomial ( has 3 terms with degree) </h3>
  • If we product the quadratic monomial and quadratic trinomial we have
  • x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)
  • =x^4+2x^3+3x^2
  • Therefore x^2(x^2+2x+3)=x^4+2x^3+3x^2 which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and x^2+5 be the linear binomial has two terms with degree 1</h3>
  • If we product the linear monomial and quadratic binomial we get
  • x\times (x+5)=x(x)+x(5)
  • =x^2+5x
  • Therefore x\times (x+5)=x^2+5x which is a quadratic binomial with degree 2

An ice chest contains 9 cans of apple juice6 cans of grape juice5 cans of orange juiceand 4 cans of pineapple juice Suppose that
KatRina [158]

Answer:

243/506

Step-by-step explanation:

There are 24 total juice boxes.

18 of them are not grape

You have an 18/24 chance of picking not grape juice

The second time, 1 is removed, then another is removed. This creates:

(18/24)*(18/23)*(18/22) = 243/506
