30 POINTS!!<br> Will give brainliest <br><br> What is ​ BC ​ ? Enter your answer in the box. units
Gemiola [76]

Answer:

BC=25

Step-by-step explanation:

this is an isosceles  triangle, so sides AB and sides AC are equal

AB = AC

4x+1 = 2x+23

subtract 2x from each side

2x+1 = 23

subtract 1 from each side

2x =22

divide by 2 on each side

x =11

BC = 3x-8

substitute the value of x

BC = 3*11 -8

BC = 33 -8

BC=25

A consultant advises the owners of a phone company that their profit
KATRIN_1 [288]

Answer:

$15.63 ≤ x ≤ $54.365

Step-by-step explanation:

Profit of the phone company is modeled by the equation,

p(x) = -50x² + 3500x - 2500

For the profit of at least $40000,

-50x² + 3500x - 2500 ≥ 40000

-50x² + 3500x ≥ 40000 + 2500

-50x² + 3500x ≥ 42500

-x² + 70x ≥ 850

x² - 70x + 850 ≤ 0

By quadratic formula,

x - intercept of the inequality will be,

x = \frac{-(-70)\pm \sqrt{(-70)^2-4(1)(850)}}{2(1)}

x = \frac{70\pm \sqrt{1500}}{2}

x = 15.635, 54.365

Therefore, $15.635 ≤ x ≤ $54.365 will be the range of cost for which profit will be at least $40000.

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

  • 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.
