*PLEASE HELP ME* (math attachment) IT'S PAST MIDNIGHT I'M TIRED AND DESPERATE

Luda [366]

<h3><u>Answer:</u></h3>

<h3><u>Step-by-step explanation:</u></h3>

let's rewrite this

x + y = 11 <em>- equation 1</em>

- x = - y - 9 <em>- equation 2</em>

solve the first equation for x

x + y = 11 (add -y to both sides to get x by itself)

x = -y + 11 <em> - equation 3</em>

now substitute -y + 11 for x in the second equation

y - 11 = - y - 9 (2 negative signs next to each other equals positive)

2y - 11 = -9 (add y to both sides)

2y = 2 (add 11 to both sides)

y = 1 (divide both sides by 2)

now substitute y = 1 into equation 3

x = -1 + 11

x = 10

therefore, x = 10 and y = 1. in coordinates, x goes before y

therefore, the coordinates are (10, 1)

therefore the answer is D

good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

Mr. Fernandez uses 7 boards that are 4 feet long and 6 inches wide to make on bookshelf. If he buys lumber in lengths of 8 feet

True [87]

Bookshelf =7boards each
Lumber=4 boards each
He wants to make 5 bookshelves total
5x7=35
So he needs 35 boards
And each lumber makes 4 boards
So what number times 4 is equal to or more than 35?

9times 4 is 36

So he needs 9 pieces of lumber to make 5 bookshelves.

Good luck with your work! Brainliest would be appreciated :)
