Answer:

1: x=y-3 linear equation : y=x+3

2:y=-2x-3 linear equation : y=-2x-3

3: -4y+6 =2 linear equation : y=2-6/-4 ⇒ y=1

4:2/3 x-1/3y=2 , linear equation : y=2x-6

-1/3 y=2-2/3 x

y=-6+2x

13: 5x+25=y² not linear

y = √5x+25

14 : 8+y=4x linear y=4x-8

15: 9xy-6x=7 not linear

16: 4y²+9=-4 ⇒ y²=-4/4 -9/4 ⇒y=√-1-2.25 ⇒y=√-3.25 not linear

17: 12x=7y-10y linear : y=12x/-3 ⇒ y=-4x

18:y=4x+x linear y=5x

Arrange the equations in increasing order of the value of their solutions.

Ulleksa [173]

See the explanation

<h2>Explanation:</h2>

The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

$f(x)=g(x)$

For each graph, $f(x)$ will be drawn in red while $g(x)$ will be drawn in blue.

Case 1:

$f(x)=\frac{1}{4}x+\frac{5}{2}x-2 \\ \\ g(x)=4-\frac{1}{4}x$

So by equating both equations:

$\frac{1}{4}x+\frac{5}{2}x-2=4-\frac{1}{4}x$

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:

<u>Solution:</u>

$\boxed{x=2}$

See First Figure below.

Case 2:

$f(x)=7.9x+x+4 \\ \\ g(x)=-1.1x-16$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-5.8}$

See Second Figure below.

Case 3:

$f(x)=3.2x+5.7 \\ \\ g(x)=-2.5x$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-1}$

See Third Figure below.

Case 4:

$f(x)=10.1x-1.6x+44 \\ \\ g(x)=-7$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-6}$

See Fourth Figure below.

−3(y+5)=15 someone please help me with this question my assignment is already late

AnnyKZ [126]

Answer: -10

Step-by-step explanation:

Simplifying

-3(y + 5) = 15

Reorder the terms:

-3(5 + y) = 15

(5 * -3 + y * -3) = 15

(-15 + -3y) = 15

Solving

-15 + -3y = 15

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + -3y = 15 + 15

Combine like terms: -15 + 15 = 0

0 + -3y = 15 + 15

-3y = 15 + 15

Combine like terms: 15 + 15 = 30

-3y = 30

Divide each side by '-3'.

y = -10

Simplifying
