Answer:

18x^2 - 9

Step-by-step explanation:

y = f(x)= 6x^3 - 9x + 4

dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)

=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)

=6.3x^2 - 9.1 + 0 =18x^2 - 9

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given n^{th} of the sequence

   aₙ = 5 n -1

Put n=1

 a₁ = 5(1)-1 = 5-1 =4

First term of the sequence = 4

If x = 8 and y = -3, evaluate the following expression: 20 - 5y + 2x​
solniwko [45]

Answer:

51

Step-by-step explanation:

Given the following question:

20-5y+2x
x=8
y=-3

Substitute and solve using PEMDAS:

20-5y+2x
20-5(-3)+2(8)
5\times-3=-15
20--15+2(8)
2\times8=16
20-(-15)+16
20--15=35
35+16=51
=51

Your answer is "51."

Hope this helps.
