Answer:

x - x=\frac{-3}{2} y+6

y - y=\frac{-2}{3} x+4

Step-by-step explanation:

Let's solve for x first.

Add -3y to both sides..

2x+3y-3y=12+-3y

2x=-3y+12

Divide both sides by 2..

\frac{2x}{2} =\frac{-3y+12}{2}

Your answer for x:

x=\frac{-3}{2} y+6

Then, solve for y.

Add -2x to both sides..

2x+3y+-2x=12+-2x

3y=-2x+12

Divide both sides by 3..

\frac{3y}{3}= \frac{-2x+12}{3}

Your answer for y:

y=\frac{-2}{3} x+4

⭐Hola User____________

⭐Here is Your Answer...!!

___________________

↪LINEAR EQUATIONS..

↪Since the equation given is

↪2x + 3y = 12

↪and the point given is (_,8)

to find the coordinate X or the abssicssa

↪we substitute the value of y = 8

↪therefore. ,, 2x +3 (8) =12

↪=》 2x + 24 = 12 =》 2x = 12-24 =》 2x = -12 =》 x = -6

↪thus , X = -6

↪points = ( -6 ,8)

Step-by-step explanation:

Ashley:

12n (n=5) = 60+2u (u=10)=80

4 quarters equal a dollar

$1.80

Beto:

10n (n=5)= 50+ 4u (u=10) = 90

3 quarters equal .75

3) Lane and Zack purchased a house for $245,000 in 2016. The house loses 4% of its value each year,
alina1380 [7]

Answer:

$138,345

Step-by-step explanation:

This is a compound decline problem, which will be solve by the compound formula:

F=P(1-r)^t

Where

F is the future value (value of house at 2030, 14 years from  2016)

P is the present value ($245,000)

r is the rate of decline, in decimal (r = 4% = 4/100 = 0.04)

t is the time in years (2016 to 2030 is 14 years, so t = 14)

We substitute the known values and find F:

F=P(1-r)^t\\F=245,000(1-0.04)^{14}\\F=245,000(0.96)^{14}F=138,344.96

Rounding it up, it will be worth around $138,345 at 2030

42 /48 in simplest form
zloy xaker [14]

<span>First we need to find the GCF (greatest common factor)</span>

<span>Factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42</span>

<span>Factors of 48 are:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48</span>

<span>GCF is 6</span>

<span>To simplify you divide numerator and denominator into the GCF</span>

<span>42 ÷ 6 = 7</span>

<span>48 ÷ 6 = 8</span>

<span>42/48 = 7/8</span>

<span>Hope this helps. :)

For each function, do the following: a) state the name of the function, b) identify the independent and dependent variable, c) i
daser333 [38]
<h2>Hello</h2>

The answers are:

a) The name of the function is g, and it's an Exponential Function.

b) Independent variable : x , dependent variable : g(x)/y

c) The rule that assigns exactly one output to the very input is called "function".

d) g(4)=2^{4}+12=16+12=28

<h2>Why?</h2>

Usually, the name of a function (g(x)) is given by letter that is out of the parentheses. For this exercise,  the name of the function is "g", and it's an Exponential Function.

The independent variable of a function is the variable we assign the different values. For this exercise, the independent variable is designated with the letter "x".

The dependent variable is the function itself (g(x)), it's also called "y",  and it's called "dependent" variable because its values will always depend on the "independent variable".

A function is the rule that states that there is exactly one output (range value) to the each input (domain value).  A function only exists when there is exactly one output value (range) for each input (domain), if there is more than one output for each input, the function does not exist.

To evaluate a function we need to assign values to the independent variable(x), therefore:

g(4)=2^{4}+12=16+12=28

Have a nice day!
