Starting from a height of 1129 ft you gain 99 Dr each additional hour of climbing ​
-Dominant- [34]

Answer:

1129 + 99x

Step-by-step explanation:

Let us use x in this equation; x = amount of hours.

You are currently at 1,129 ft.; so lets start with that.

After then you don't know how many hours you climb but you know at what pace. So you use a variable to plug in with numbers later.

So your equation turns into;

1,129 + 99x

A parabola opens upward. The parabola goes through the point (3, -1), and the vertex is at (2, -2). write the equation of the pa
Lorico [155]

The value of a is 1/4 and the equation of the parabola is (x-2)² = (y+2)

<h3>What is a Parabola ?</h3>

A parabola is a u shaped curve. It is a plane curve whose all points are at a fixed distance form a point called focus.

(x-h)² = 4a(y-k)

It is given that the parabola goes through the point (3, -1), and the vertex is at (2, -2).

Therefore
(x -2)² = 4a(y +2)

The parabola passes through the point (3,-1)

(3-2)² = 4*a(-1+2)

1 = 4 a

a = 1/4

The equation of the parabola is

(x-2)² = (y+2)

Therefore The value of a is 1/4 and the equation of the parabola is (x-2)² = (y+2)

a student bought a juice pouch for $2.50 and 3 bags of chips. the total cost was $5.05 write and solve an equation to determine
Wittaler [7]

First, write it as an equation

2.50+3x=5.05

Next, subtract 2.50 from both sides

2.50-2.50+3x=5.05-2.50

3x=2.55

Divide 3 on both sides

3x/3=2.55/3

x=0.85

The cost of a bag of chips is 0.85

hope i helped :D

Amy is 9 years older than her younger sister. if her younger sister is now 1 year old, how many years later will Amy be 4 times
Sholpan [36]
<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

  • Age of Amy's younger sister=1year

☆Amy is 9 years older than her younger sister.

\\ \sf\longmapsto Age\:of\:Amy=1+9=10years

Let after x years Amy will be 4times old as her sister.

ATQ

\\ \sf\longmapsto \dfrac{1+x}{9+x}=\dfrac{1}{4}

  • Using cross multiplication

\\ \sf\longmapsto 4(1+x)=1(9+x)

\\ \sf\longmapsto 4+4x=9+x

\\ \sf\longmapsto 4x-x=9-4

\\ \sf\longmapsto 3x=5

\\ \sf\longmapsto x=\dfrac{5}{3}

\\ \sf\longmapsto x=1.6

\\ \sf\longmapsto x=2(approx)
