\bf ~~~~~~\textit{parabola vertex form} \\\\ y=a(x- h)^2+ k \qquad\qquad vertex~~(\stackrel{}{ h},\stackrel{}{ k}) \\\\[-0.35em] ~\dotfill\\\\ y=(x-5)^2\implies y=(x-\stackrel{h}{5})^2+\stackrel{k}{0}~~\checkmark \\\\\\ y=(x+5)^2\implies y=[x-(-5)]^2\implies y=[x-(-\stackrel{h}{5})]^2+\stackrel{k}{0}~~\checkmark

PLEASE HELP ME FAST!! ( It's about y-intercept)
Alex_Xolod [135]

Answer:

y = 10x + 8

Step-by-step explanation:

1. The slope-intercept form of an equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Since we're given the value of slope and y-intercept, we just have to plug in those values to it's corresponding variable.

  • 10 = m, and 8 = b.
  • y = 10x + 8

Addition (must show work) can someone solve 1. m + 13 =29 2. z + x =34 <br><br> 3. 87 + p = 136
azamat

Greetings ! Your Answer Is Below.

Answer;

1. m = 16

2. x = -z + 34 or z = -x + 34

3. p = 49

Step-by-step explanation;

1. m + 13 - 13 = 29 - 13       | Subtract 13 from both sides ( m = 16 )

2. - z + 34                          | Add -z to both of the sides ( x = - z + 34 )

Or - x + 34                         | Add -x to both of the sides ( z = - x + 34 )

3. 136 - 87 = 49                 | Subtract 87 from both sides ( p = 49 )

Tom bought one third pickles as many pickles as alexa. Together their pickles cost 56p. How many pickles did they each buy?
nordsb [41]

Answer:

Step-by-step explanation:

let    pickle bought by alexa =x

then according to given condition ,

pickle bought by Tom= (1/3) of Alexa

pickle bought by Tom= (1/3) x

hence also given

totall pickle cost = Tom cost + alexa cost = 56p

(1/3)x+x=56

taking L.C.M

(4/3)x=56

x=56*3/4

x=42 p

so it means,

<h2>Alexa cost = x = 42p</h2><h2>Tom cost = (1/3)x= (1/3)*42 = 14 p</h2>
