Hey there!

The answer would be 11/40

There's 40 tickets in total and you have 11. So you take how much you have over the total there is!

Hope this helped!

Select the correct answer from each drop-down menu. y = x2 + 2x − 1 y − 3x = 5 The pair of points representing the solution set
katen-ka-za [31]

ANSWER

(-2,-1)

(3,14)

EXPLANATION

The given system is

y =  {x}^{2}  + 2x - 1

y - 3x = 5

or

y = 3x + 5

Equate both of them:

{x}^{2}  + 2x - 1 = 3x + 5

This implies that,

{x}^{2}   - x - 6 = 0

(x - 3)(x + 2) = 0

x=-2 or x=3

When x=-2, y=y=3(-2)+5=-1

(-2,-1) is a solution.

When x=3 , y=3(3)+5=14

(3,14) is also a solution.

3(a - 4) ≤ 33<br> Help me solve
yaroslaw [1]

Answer:

a ≤ 15

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

3(a - 4) ≤ 33

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Divide 3 on both sides:                    a - 4 ≤ 11
  2. Add 4 on both sides:                        a ≤ 15

Here we see that any value <em>a </em>less than or equal to 15 would work as a solution to the inequality.
