PLEASE HELP

Andru [333]

ANSWER

$q = - 7p$

EXPLANATION

The constant difference of p values is

4-2=2

The constant difference of the 'q' values is

-28--14=-14

The function is of the form:

$q = m(p - p_1) + q_1$

where

$m = \frac{change \: in \:q }{change \: in \: p}$

$m = \frac{ - 14}{2} = - 7$

We plug in the values to get;

$q = - 7(p - 2) + - 14$

Expand:

$q = - 7p + 14+ - 14$

Simplify:

$q = - 7p$

1/2(x-4)=1/3(x+2) <br> Helppp plsss will give brainilist

melamori03 [73]

Answer:

x= 16

Step-by-step explanation:

combine multiplied terms into a single fraction

$\frac{1}{2} (x-4)=\frac{1}{3} (x+2)$

$\frac{1(x-4)}{2} =\frac{1}{3} (x+2)$

Multiply by 1

$\frac{1(x-4)}{2} =\frac{1}{3} (x+2)$

$\frac{x-4}{2} =\frac{1}{3} (x+2)$

Combine multiplied term into a single fraction

$\frac{x-4}{2} =\frac{1(x+2)}{3}$

Multiply by 1

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

Multiply all terms by the same value to eliminate fraction denominators

$6*\frac{x-4}{2} 6(\frac{x+2}{3} )$

cancel multiplied terms that are in the denominator

$3(x-4)=2(x-2)$

Distribute

$3x-12=2(x+2)$

Distribute

$3x-12=2x+4$

Add 12 to both sides of the equation

$3x-12+12=2x+4+12$

Simplify

$3x=2x+16$

Subtract 2x from both sides of the equation

$3x=2x=2x+16-2x$

Simplify

$x=16$
