Option B is correct.

Step-by-step explanation:

Paul was asked to use the elmination to find the solution to the system of linear equations

5x + 4y = 1\\-2x-8y = -26

What are the missing steps in his work below?

Let\\5x + 4y = 1\,\,eq(1)\\-2x-8y = -26\,\,eq(2)\\10x + 8y = 2 + (-2x-8y = -26) \\8x + 0y = -24 \\8x = -24 \\x = -3 \\Putting\,\,value\,\,of\,\,x\,\,in\,\,eq(1)\\5x + 4y = 1 \\5(-3) + 4y = 1\\-15 + 4y = 1 \\4y = 16\\y=4

So, the step missing is multiplying equation 1 by 2 i.e

2\times [5x + 4y = 1] \\10x + 8y = 2

So, Option B is correct.

Determine the first five iterates of f(x)=1.5x(1-x) for x0=0.8
kherson [118]
<span>f(x) = 1.5 x (1 - x)
f(0.8) = 1.5(0.8)(1 - 0.8) = 0.24
f(0.24) = 1.5(0.24)(1 - 0.24) ~= 0.274
f(0.274) = 1.5(0.274)(1 - 0.274) ~= 0.298
f(0.298) = 1.5(0.298)(1 - 0.298) ~= 0.314
f(0.314) = 1.5(0.314)(1 - 0.314) ~= 0.323

</span>So the answer is D : 0.24, 0.274, 0.298, 0.314, 0.323
