289 and y more is 206

Mathematics
1 answer:
hammer [34]3 years ago
7 0

Answer:  

Equation translates to 289 + y = 206

it solves to y = -83

====================================================

Explanation:

The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.

Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206

This is the same as saying y+289 = 206

To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides

y+289 = 206

y+289-289 = 206-289

y = -83

So we are adding -83 to 289 to get 206

The profit (in thousands of dollars) of a company is given by P(x) = -8x2 + 32x + 14.
andre [41]

Answer:

C

Step-by-step explanation:

The profit (in thousands of dollars) of a company is given by the function:

\displaystyle P(x) = -8x^2+32x+14

And we want to find the maximum profit of the company.

Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex. Recall that the vertex of a quadratic is given by:

\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)

Find the <em>x-</em>coordinate of the vertex. In this case, <em>a</em> = -8, <em>b</em> = 32, and <em>c</em> = 14. Hence:

\displaystyle x=-\frac{(32)}{2(-8)}=\frac{32}{16}=2

To find the maximum profit, substitute this value back into the function. Hence:

\displaystyle P(2) = -8(2)^2+32(2) + 14 = 46

Therefore, the maximum profit of the company is 46 thousand dollars.

Our answer is C.

Rewrite the expression in the form y^n
bazaltina [42]

Answer:

$ y^6 $

Step-by-step explanation:

$ \frac{a^b}{a^c} = a^{b - c} $

Using this rule we have:

$ \frac{y^{-7}}{y^{-13}}  = y^{-7 -(-13)} = y^6$

You have a part-time job. You work for 3 hours on Friday and 6 hours on Saturday. You also receive an allowance of $20 per week.
olga55 [171]

Answer:

8 dollars per hour

Step-by-step explanation:

You make 92 a week

20 of that is from your allowance

92-20 = 72

72 is from your part time job

You work for 3 hours on Friday and 6 hours on Saturday, for a total of 3+6 = 9 hours

Take the amount of money earned and divide by the number of hours to determine the money earned per hour

72/9 = 8 dollars per hour
