Step-by-step explanation:

Solving

3x + -6y = 42

Solving for variable 'x'.

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

Add '6y' to each side of the equation.

3x + -6y + 6y = 42 + 6y

Combine like terms: -6y + 6y = 0

3x + 0 = 42 + 6y

3x = 42 + 6y

Divide each side by '3'.

x = 14 + 2y

Simplifying

x = 14 + 2y

Answer:

y = -1/2x + 7

Step-by-step explanation:

3x + 6y = 42

<u>-3x          -3x  </u>

<u>6y = -3x + 42</u>

6       6       6

vlada-n [284]
The formula for this is A= \frac{1}{2} ( b_{1} + b_{2} )h.  Filling in accordingly, 36= \frac{1}{2}(x+2x)(4).  This simplifies to 36= \frac{1}{2}(3x)(4) and 36=6x.  Therefore, x = 6 so the bases are 6 and 12.

Find the distance between each pair of points E(-1, 0),F(12, 0)
Olegator [25]

Answer:

The answer is

<h2>13 \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\ </h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

E(-1, 0) and F(12, 0)

The distance between them is

<h3>|EF|  =  \sqrt{ ({ - 1 - 12})^{2}  +  ({0 - 0})^{2} }  \\  =  \sqrt{ ({ - 13})^{2} }  \\  =  \sqrt{169}</h3>

We have the final answer as

<h3>|EF| = 13 \:  \: units</h3>

Hope this helps you

What is th difference in length between a 1 1/4 inch button and a 3/8 inch button
artcher [175]
Okay so 11/4 needs to be multiplied by 2 so that the D match up.

so 11/4 x 2 =  22/8

22/8  -  3/8  = 19/8

The difference is 19/8
