What is 3y+5x=-15 written in slope-intercept form

2 answers:

7 0

Slope-intercept form is y=mx+b, so we simply have to solve for y...

3y+5x=-15 subtract 5x from both sides

3y=-5x-15 divide both sides by 3

y=-5x/3-5 or more neatly in my opinion...

y=(-5x-15)/3

Mike is 29.

5+2x+x=41
5+3x=41
3x=36
x=12

5+2x=Mike’s Age
5+2(12)= Mike’s Age
29= Mike’s Age

Phoenix [80]

<h3><u>Solution</u><u>:</u><u>-</u></h3>

J (1,5)
K (1,9)

$\LARGE\leadsto\sf JK=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\LARGE\leadsto\sf \sqrt {(1-1)^2+(9-5)^2}$

$\LARGE\leadsto\sf \sqrt {(0)^2+(4)^2}$

$\LARGE\leadsto\sf \sqrt {0+16}$

$\LARGE\leadsto\sf \sqrt {16}$

$\LARGE\leadsto\sf JK=4units$

AB is similar to YZ
AC is similar to YX
CB is similar to XZ

you put the triangles next to each other. since they are the same shape. same kind of triangle. one is just bigger than the other.
