Mathematics
1 answer:
dmitriy555 [2]3 years ago

Answer:

She made a mistake in Step 7.

Step-by-step explanation:

Step 1 through 6 are correct. Only from Step 6 to Step 7 the problem comes in: both sides of the equation are multiplied by x, however the x on the left side, by error, becomes 1. The correct state in Step 7 should look like this:

x(\frac{1}{2}P-x)=256

you earn $420 per week. You pay social security taxes of 7.65% federal taxes of 22%, and state taxes of 5.95%. What is your take
Marysya12 [62]
First you need to solve for how much you lose for each individual tax, so 420x.0765 will give you how much money you lose to social security tax, then do the same for the other types and add them together, the value will give you the amount you have lost, so taking the total (420) minus the amount lost you will have the amount that you can "take home" So 420-((420x.0765)+(420x.22)+(420x.0595)) = amount still in your pocket

I need help solving this
Kruka [31]

Answer: y = -x + 5

Step-by-step explanation:

      A slope-intercept equation is in the form y = <em>m</em>x + <em>b</em> where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept. Since we are given the slope, we will plug it in with the point they gave us, and solve for <em>b</em>.

y = <em>m</em>x + <em>b</em>

(1) = (-1)(4) + <em>b</em>

1 = -4 + b

5 = b

      Lastly, we will write our equation by substituting <em>m</em> with -1 and <em>b</em> with 5.

y = <em>m</em>x + <em>b</em>

y = -1x + 5 or y = -x + 5

Lf g(x) = x3 - 5 and h(x) = 2x - 2, find g(h(3)).
White raven [17]

Answer: g(h(3)) = 59

Step-by-step explanation:

Well if its x^3 I assume it is because you wrote other coefficients before the variable.

2(3) - 2 = 6-2 = 4

So 4 is the x input for h(x)

4^3 -5 = 64-5 = 59
