Answer: x = 12, y = -8

Step-by-step explanation:

If you do substitution:

4(-y+4) + 6y = 0

-4y + 16 + 6y = 0

2y + 16 = 0

2y = -16

y = -8

x = -(-8) + 4

x = 8 + 4

x = 12

(X,y) (12,-8) this should be the answer

Suppose the distance between x and zero is 6. write an inequality

kvasek [131]

0 < /6/ (absolute value)

That is your inequality since the subject is about the distance away from zero then using common sense you would make the 6 get put in between the 2 absolute value lines ( not trying to be rude, if the explanation seems rude to you im sorry)

6 <em>(town A)</em> - 6 <em>(town B)</em> = 0

Are they symmetric?

<em>No, I believe not,</em> they don't align center in the same way, according to the pictures I've attached. The one with a short box is Town A, the bigger box is Town B.

1. According to a recent survey, 13 out of the 33 students in a class take the bus to school. What is the ratio of students who

AlexFokin [52]

Answer: (1) 13/20 (2) 8 (3) Yes. They are proportional

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

(1) 13 students take the bus.

33 - 13 = 20 students do not take the bus

$\dfrac{\text{take the bus}}{\text{do not take the bus}}:\dfrac{13}{20}$

(2)

$\dfrac{2\ red}{3\ green}=\dfrac{x}{12\ green}\\\\\\\underline{\text{cross multiply}:}\\2(12)=3(x)\\24=3x\\8=x$

(3)

$\dfrac{6}{10}\div \dfrac{2}{2}\quad =\dfrac{3}{5}\\\\\\\dfrac{9}{15}\div \dfrac{3}{3}\quad =\dfrac{3}{5}\\\\\\\dfrac{15}{25}\div \dfrac{5}{5}\quad =\dfrac{3}{5}$
