Answer:

I'd need to see the lines but basically, parallel lines have to be directly across from each other and they have to be the same size, I put a pic so you can see what I mean

Hope this helps you

Given that f(x)=x^2-3x+3 and g(x)=x-1/4 slove for f(g(x)) when x=5
Y_Kistochka [10]
When x=5, f(g(x)) would be (x-1/4)^2 - 3(x-1/4) + 3 which when you plug 5 in for x, you get 11.3125 as an answer

Jason is paid 500 per month plus a commission of 4% of the first 2500 of his sales, and 6% of his sales over 2500. last month hi
Deffense [45]
Begin by subtracting 2500. 22600-2500=20100. Multiply 2500 by .4. 2500×.4=1000
Now, multilply the other number we found by .6. 20100×.6=12060. Add the two numbers, and the original 500 for Jason's gross pay for the month.
500+1000+12060=13,560
Jason's gross pay for the month is $13560.

Can you please help me solve 18 and 21 please?

<h3>Answer:</h3>

18. x = y = -3

21. y was substituted into the wrong equation. The solution is (x, y) = (2, 1).

<h3>Step-by-step explanation:</h3>

18. Adding y to the first equation transforms it to ...

... x = y

Then you can substitute for either variable in the second equation.

... 2y -5y = 9 . . . . . substitute for x

... -3y = 9 . . . . . . . . simplify

... y = -3 . . . . . . . . . divide by the coefficient of y

.. x = -3 . . . . . . . . . x and y have the same value

___

21. The first equation is being used to find an expression for y in terms of x. If you substitute that expression back into the same equation, it will tell you nothing you didn't already know. (Here, it is telling you 5 = 5.) The expression is only useful if you <em>substitute it into a different equation</em>. Here, it needs to be substituted into the second equation:

... <u>Step 2</u>: 3x -2(-2x+5) = 4 ⇒ 7x -10 = 4 . . . . . substitute for y in the second eqn

... <u>Step 3</u>: 7x = 14 . . . . . add 10

... <u>Step 4</u>: x = 2 . . . . . . . divide by 7

... <u>Step 5</u>: y = -2·2 +5 = 1 . . . . . find the value of y from x using the expression from step 1. Now, you know the solution is (x, y) = (2, 1).

_____

The attached graph shows the solution to the problem of 21.
