The meaning of (f + g)(-1) is you substitute -1 to x of whatever polynomial you obtain after adding the polynomials f(x) and g(x).
                    f(x) + g(x) = -2x + 8 + 3x = x + 8
Substitute -1,
                        (f + g)(-1) = -1 + 8 = 7.
Thus, the answer is 7.

Calculate the pay for the following day of a weekly time card given a wage of $14.50/hr. Name Week of: SI Morning lo Out Monday
Vanyuwa [196]

As we can see in the card, on Monday the worker clocked in at 08:15 and clocked out at 12:15. This means they worked 4 hours.

They then clocked in at 13:00 and clocked out at 17:30. This means they worked for 4 and a half hours.

Since they earn a wage of $14.50/h, they earned:

(4+4.5)\cdot14.50=8.5\cdot14.50=123.25.

So that day they earned $123.25

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

There is no effect of dilation on the angle.

Doubling the dimensions of a rectangle increases the area by a factor of 4.

If p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4.

Then the true statement will be

Then the correct options are A and E.

Please HELPPPPP!!! <br><br> I DONT KNOW WHY IM GETTING THEM WRONG
Nady [450]

Answer:

n = -33

Step-by-step explanation:

Let n = number

Sum of a number and 9

(n+9)

is tripled

3(n+9)

the result is six less then twice the number

2n-6

3(n+9) = 2n-6

Distribute

3n+27 = 2n-6

Subtract 2n from each side

3n-2n +27 = -6

n +27 = -6

Subtract 27 from each side

n+27-27 = -6-27

n =-33
