Answer:

C) -3 x2 + 6

Step-by-step explanation:

Given algebraic expressions are:

  • \[2x^{2}+3x-4\]
  • \[8-3x\]
  • \[-5x^{2}+2\]

Adding the given expressions:

\[2x^{2}+3x-4 + 8-3x + (-5x^{2}+2)\]

Simplifying:

\[2x^{2}-5x^{2}+3x-3x-4 + 8 + 2\]

\[= (2-5)x^{2}+(3-3)x+(8 -4 + 2)\]

\[= -3x^{2}+6\]

Among the given options, this is equivalent to option C.

How is the graph of y=log(x) transformed to produce the graph of y=log(2x)+3
V125BC [204]

Answer:

  • horizontally compressed by a factor of 2 and translated upward by 3 units.

Step-by-step explanation:

A multiplier of x in a function transformation is effectively a compression factor. That is f(2x) will have half the horizontal extent of f(x) for the same values of x.

Addition of a constant the the value of a function effectively translates the graph upward by that amount. The graph of y = log(2x) +3 has been translated upward 3 units.

The graph of y=log(x) has been horizontally compressed and translated upward to produce the graph of y = log(2x) +3.

A salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of ​$28. Opti
irina [24]

Answer:

$9500

Step-by-step explanation:

Given, Option A: Hourly wage is $19 and the salesperson works 40 hours per week. So, he will earn in a week= 19 X 40 = $760

Now, according to option b, he will get 8% commission on weekly sales.

Let. x = the amount of weekly sales.

To earn the same amount of option A, he will have to equal the 8% of x to $760

So, 8x/100= 760

Or, 8x= 76000

Or, x= 76000/8= 9,500

the salesman needs to make a weekly sales of $9,500 to earn the same amount with two options.
