Write the equation 2x - 3y = 6 in slope-intercept form. User: Write the equation for 5x + 2y = 3 in slope-intercept form.
evablogger [386]
Slope intercept form is: y=mx+b

So you take the first equation: 2x-3y=6 and you subtract the 2x from both sides and get: -3y= 2x+6

Then you take that equation: -3y= 2x+6 and divide -3 from both sides and get: y= -2/3x -2

So the equation 2x-3y=6 in slope intercept from is
y = -2/3x -2


Can you do the next one your self based on the one i did...?

(Scroll and check ⬇️ )


























Here ya go ;)

5x + 2y = 3 okay same steps as above you want to get the x on the other side so you subtract the 5x from both sides and get:

2y = 5x + 3

Then you want to get the y by its self so you divide the 2 from both sides so you get:

y = 5/2x +2/3

Now idk if your allowed to leave it like that (based on your teacher's preferance really) but if not you can simplfy your fractions and get:

y = 2.5x + 0.66

( i would leave the 2/3 and just leave it as y = 2.5x + 2/3 ) but you do you and i hope that helped you :)

Solve for r. s=2πrh
Butoxors [25]

Answer:

 s/2πh =r  

Step-by-step explanation:

s=2πrh

Divide both sides by 2πh to isolate r

 s/2πh =2πrh /2πh  

 s/2πh =r

Can someone please help me????? Please I'm not good with Geometry
Otrada [13]

The hurdle and runner form a right triangle (see attached picture) such that

sin(30°) = <em>h</em> / (5 ft)

and

cos(30°) = <em>x</em> / (5 ft)

where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So

<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft

<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
