The most simple form (I'm defining the parabola to be an upwards-opening one) would be $y=(x-1) ^{2} +3$

Which of these strategies would eliminate a variable in the system of equations?

KATRIN_1 [288]

Answer: A and B

Explanation: I’ll use A as an example. When you multiply the bottom equation by -3/2, the equation becomes: -9x+6y=-3. Then, proceed to add the equations. Look at X and Y in both equations: do the Y variables in both equations equal to 0 when added together? Yes, because -6y+6y=0! Therefore, you can eliminate y in these two equations.

Hope that’s helps シ

Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary)

ki77a [65]

Answer:

$j(s) = 0.05s -500$

Step-by-step explanation:

Given

$Base\ Salary = 2000$

$Commission = 5\%$ on Sales over 50000

Required

Determine the function j(s) for sales over 50000

Represent the total sales in a month with s.

Sales over 50000 in that month will be: s - 50000

So, the function j(s) is:

j(s) = Base Amount + Commission * Sales over 50000

$j(s) = 2000 + 5\% * (s - 50000)$

Convert % to decimal

$j(s) = 2000 + 0.05 * (s - 50000)$

Open bracket

$j(s) = 2000 + 0.05 * s - 0.05 * 50000$

$j(s) = 2000 + 0.05s - 2500$

Collect Like Terms

$j(s) = 0.05s - 2500 + 2000$

$j(s) = 0.05s -500$
