HELP <br> what is the equation of the lines in slope - intercept form
34kurt

Answer:

y=7x

Step-by-step explanation:

slope intercept form is y=mx+b.

m is the slope (rise over run) and b is your y- intercept. you leave y as it is. if the line is going down, you have a negative slope. hope this helped :)

A cherry falls from a tree branch that is 9 feet above the ground.
miss Akunina [59]
The cinematic equation is:
 h (t) = (1/2) * a * t ^ 2 + vo * t + h0
 Where,
 a: acceleration
 vo: initial speed
 h0: initial height
 Substituting values:
 h (t) = (1/2) * (- 32) * t ^ 2 + (0) * t + 9
 h (t) = - 16t ^ 2 + 9
 For t = 0.2 we have:
 h (0.2) = - 16 * (0.2) ^ 2 + 9
 h (0.2) = 8.36 feet
 To touch the ground we have:
 -16t ^ 2 + 9 = 0
 16t ^ 2 = 9
 t = root (9/16)
 t = 0.75 s
 Answer:
 
The height of the cherry after 0.2 seconds is:
 
h (0.2) = 8.36 feet
 
the cherry hits the ground at:
 
t = 0.75 s

Write an equation of the line.
vladimir2022 [97]
I believe it’s y=4x+4 :)
The slop intercepts the y axis at positive 4, which gives us the y intercept
If you use the rise over run technique to find the slope you’ll get 4/1, meaning the slope is 4

Let y represent the original price of a game.
<span>Ella purchased a game that was on sale 12% off which means that the new price of the game is 88% of the original price, so:
</span>y*88/100&#10;=0.88y
Next, t<span>he sales tax in her county is 6%, which means that the the now price is 106% to the original price, so:
</span>0.88y*106/100&#10;=0.88(1.06)y&#10;=0.9328y. As a result, the final cost can represent under the form of 0.9328y. Hope it help!
