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

Luda [366]

<h3>Answer:</h3>

D

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

let's rewrite this

x + y = 11 - equation 1

- x = - y - 9 - equation 2

solve the first equation for x

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

x = -y + 11 - equation 3

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

Si mi hermano gana 589 pesos diarios si ha trabajado 15 días de este mes ¿cuánto dinero ha ganado?

weeeeeb [17]

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.

En esta pregunta debemos determinar el dinero devengado por un período de 15 días a partir de una tasa diaria constante. Esa cantidad es igual al producto de la tasa diaria constante, en pesos por día, y el número de días trabajados, en días:

$x = 589\,\frac{\$}{dia}\times 15\,dias$

$x = 8835\,\$$

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.
