Answer: Option D  g(x)= 6.3x

Explanation:

It is given that function has a vertical stretch of factor 6 so, we will multiply the factor with value of function.

If compression would have given we will divide the value of function by  given factor

Option A: when we will multiply 6 with 3x it will not give 36x

Option B and C are totally irrelevant

Hence, Option A,B and C are discarded

Solve the equations by factoring:<br><br>x^2−3x−40=0<br><br>4x^2−81=0
Alja [10]

Answer:

see explanation

Step-by-step explanation:

Given

x² - 3x - 40 = 0

Consider the factors of the constant term (- 40) which sum to give the coefficient of the x- term (- 3)

The factors are - 8 and + 5, since

- 8 × 5 = - 40 and - 8 + 5 = - 3, thus

(x - 8)(x + 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 8 = 0 ⇒ x = 8

x + 5 = 0 ⇒ x = 5

------------------------------------------------------

Given

4x² - 81 = 0 ← this is a difference of squares and factors in general as

a² - b² = (a + b)(a - b), thus

4x² - 81

=(2x)² - 9²

= (2x + 9)(2x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 9 = 0 ⇒ 2x = - 9 ⇒ x = - \frac{9}{2}

2x - 9 = 0 ⇒ 2x = 9 ⇒ x = \frac{9}{2}

Find the new price after the markdown given. Round to the nearest cent if necessary. $5,250 marked down 15%
PIT_PIT [208]

Marked down 15% means the new price would be 85% of the original price ( 100%-15% - 85%)

Multiply the original price by 85%:

5250 x 0.85 = 4462.50

The new price is $4,462.50
