Answer:

f(x + 3) = -x² - 8x - 13

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  • Left to Right

<u>Algebra I</u>

  • Function Notation
  • Expanding
  • Terms/Coefficients/Degrees

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -x² - 2x + 2

f(x + 3) is x = x + 3

<u>Step 2: Find</u>

  1. Substitute in <em>x</em>:                    f(x + 3) = -(x + 3)² - 2(x + 3) + 2
  2. Expand:                               f(x + 3) = -(x² + 6x + 9) - 2x - 6 + 2
  3. Distribute -1:                        f(x + 3) = -x² - 6x - 9 - 2x - 6 + 2
  4. Combine like terms:           f(x + 3) = -x² - 8x - 13

Solve for v 2(3v+8)=70
yuradex [85]

Answer:v = 9

Step-by-step explanation:

Simplifying

2(3v + 8) = 70

Reorder the terms:

2(8 + 3v) = 70

(8 * 2 + 3v * 2) = 70

(16 + 6v) = 70

Solving

16 + 6v = 70

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '-16' to each side of the equation.

16 + -16 + 6v = 70 + -16

Combine like terms: 16 + -16 = 0

0 + 6v = 70 + -16

6v = 70 + -16

Combine like terms: 70 + -16 = 54

6v = 54

Divide each side by '6'.

v = 9

3) Tara sold candles to raise money for new playground equipment at her school.
Ronch [10]

Answer:

Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.

Step-by-step explanation:

50/5 = 10 which means that 1/5 of 50 = 10.

2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.

The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).

ira [324]

Answer:

A) 128

B) 7800

Step-by-step explanation:

Trial and error until I got to 75 x 104 and 60 x 128 (which abides by the fact that there has to be 24 more red boxes) which equals 7800 and 7680 and if you take them away from each other you get 120

Find three consecutive odd integers such that the sum of the largest and twice the smallest is 25. If x represents the smallest
Murrr4er [49]
1. x
2. x + 2
3. x + 4

x + 4 + 2x = 25. Second option is the answer.


Combine like terms
3x + 4 = 25
Subtract 4 from both sides
3x = 21
Divide both sides by 3
x = 7
