What value of k makes the statement true?<br> x² (2x³ + 7x²yª) = 2xªyª + 7x³y8?
Nina [5.8K]

By apply the distributive property of multiplication, the value of k which makes the statement true is 1.

<h3>What is the distribution property?</h3>

Mathematically, the distributive property of multiplication is given by tis expression:

x(y + z) = xy + xz.

Next, we would apply the distributive property of multiplication to the given equation by distributing to the left-hand side using xy⁴:

k(2x⁴y⁴ + 7x³y⁸) = 2x⁴y⁴ + 7x³y⁸

Dividing both sides by the common factor, we have:

k = (2x⁴y⁴ + 7x³y⁸)/(2x⁴y⁴ + 7x³y⁸)

k = 1.

In conclusion, the value of k which makes the statement true is 1.

43=0.34x+19.5<br> What is x
Angelina_Jolie [31]

Step-by-step explanation:

43=0.34x+19.5

=> 0.34x+19.5 = 43

=> 0.34x = 43 - 19.5

= 23.5

=  > x =  \frac{23.5}{0.34}

=> x = <u>69.117</u><u> </u><u>(</u><u>Ans</u><u>)</u>

Answer:

The answer to your question is a)  y = 1.5x - 6    

                                                    b)   y = -4x + 6.1

                                                    c) Point (2.2, -2.7)

Step-by-step explanation:

First line                                                Second line

P (0, -6)           Q (1, -4.5)                        R (0, 6.1)       S (1, 2.1)

m = (-4.5 + 6) / (1 - 0)                              m = (2.1 - 6.1) / (1 - 0)

m = 1.5 / 1                                                m = -4/1

m = 1.5                                                    m = -4

Line                                                         Line

  y - y1 = m(x - x1)                                   y - 6.1 = -4(x - 0)

  y + 6 = 1.5(x)                                        y - 6.1 = -4x

  y = 1.5x - 6                                           y = -4x + 6.1

Solve the system by equality

                             1.5x - 6 = -4x + 6.1

                              1.5x + 4x = 6.1 + 6

                                    5.5x = 12.1

                                         x = 12.1 / 5.5

                                         x = 2.2

Find y

                             y = 1.5(2.2) - 6

                             y = 3.3 - 6

                             y = -2.7

Point (2.2, -2.7)
