Answer:

y=-4x^2+9x+9

Step-by-step explanation:

1st: we assume the equation will be in standard form (ax^2+bx+c)

2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.

3rd: since it passes through (2,11) then 11=4a+2b+c

4th: since it also passes through (3,0) then 0=9a+3b+c

* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*

So a=-4, b=9, c=9

plug in the numbers and you get y= 4x^2+9x+9

Hope this helps you. :3

Employer A is offering you a position for $350000 per year l. Employer B is offering the same job for $18.00 per hour. Assuming

ss7ja [257]

Answer:

Depends

Step-by-step explanation:

In order to see which annual salary is higher, we must calculate the annual salary of B to compare to A. To do this, if B offers $18.00 an hour for 40 hours a week, that's $720 a week. Now to convert this to annual, multiply the weekly earnings by the 52 weeks in a year. Employer B offers $720 × 52 weeks = $37,440 annually. Assuming you didn't have a typo, $350,000 is $312,560 greater meaning A pays more. If you did have a typo, and meant that Employer A offered $35,000, then Employer B would pay more.

If a place you like is renting for $800, and you had one other renter with whom you split the rent expense, how much does your G

Yakvenalex [24]

Answer:

How much should I spend on rent and utilities?

We calculate your monthly rent at 25% of your monthly net income (after monthly debt). This allows you to have enough cash left for other expenses and savings. Utilities are in general 2.5% of your monthly net income, and so in this case, you should expect to spend $0 or more per month on utilities.

What is the solution to the equation

irakobra [83]

Answer:

x = 12

Step-by-step explanation:

5(x - 6) = 2(x + 3)

Distribute

5x - 30 = 2x + 6

Put like terms on each side by subtracting both sides by -2x and adding 30 on each side

3x = 36

Simplify

3x/3 = 36/3

x = 36/3

x = 12

Plug is back in to check

5(12) - 30 = 2(12) + 6

60 - 30 = 24 + 6

30 = 30
