How do I get the ans??
ioda

Answer:

11 sets of forks

Step-by-step explanation:

First subtract 406-278 to find total amount of forks needed which is 128 forks.

Then divide 128 by 12 to see how many sets of forks you need.

You get 10.67 but because you can't buy two thirds of a set, you have to round up to 11 sets of forks.

Hope this helps :)

What is the equation of the graph below?
Harlamova29_29 [7]

Hey there! :)

Answer:

y= cos (x+ \pi })

Step-by-step explanation:

Normally, in the parent function y = cos x, when X = π, Y = -1. However, in this graph, when X = 0π, Y = -1.

Therefore, there has been a horizontal shift of π to the left. The new equation would be:

y= cos (x+ \pi })

Simplify (3x + 5) + (2x - 9) - (4x + 3).<br><br> x - 7<br> -x - 7<br> -9x - 1<br> 9x - 1
Lyrx [107]
Hi Grant.

(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.

3x + 2x; 5 - 9; we result with: 5x - 4

Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.

(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.

5x - 4x; -4 - 3; we result with x - 7.

Your answer is A.) x - 7.

I hope this helps!
