Given: 3x+52=13<br> Prove: x = 7<br> write a two column proof

vivado [14]

The answer x = 7 is false here is why.

$3x+52=13\Longrightarrow3x=-39$

This further simplifies to solution,

$x=-\dfrac{39}{3}\Longrightarrow\boxed{x=-13}$

Hope this helps.

It’s linear so you map out the first differences and then put it into y=Mx+b form. For the you gotta find the y intercept

Alika [10]

Let's find the slope (m) :

$\dfrac{y2 - y1}{x2 - x1}$

$\dfrac{16 - 11}{9 - 6}$

$\dfrac{5}{3}$

slope of given line is 5/3

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :

$y = mx + c$

$11 = \bigg(\dfrac{5}{ 3} \times 6 \bigg) + c$

$11 = (5 \times 2) + c$

$11 = 10 + c$

$c = 11 - 10$

$c = 1$

value of y - intercept (c) = 1, so our equation will be :

$y = mx + c$

$y = \dfrac{5}{3}x + 1$
