What is the equation of the parabola in vertex form?
Snowcat [4.5K]

The vertex form of a parabola:

y=a(x-h)^2+k

You have y². It's not a function. OK. But away, the graph is a parabola but it is horizontal parabola.

y^2-x+2y-3=0\ \ \ \ |+x+3\\\\y^2+2y=x+3\\\\y^2+2\cdot y\cdot1=x+3\ \ \ \ |+1^2\\\\\underbrace{y^2+2\cdot y\cdot1+1^2}_{use:(a+b)^2=a^2+2ab+b^2}=x+4\\\\\boxed{(y+1)^2=(x+4)}

Your answer is:

<h3>(x+4) = (y + 1)²</h3>

Help! ASAP PLEASEEE
jarptica [38.1K]

Answer:

Week and a day

Step-by-step explanation:

You have $30, you save $5 each week and your aunt gives you an extra $10. Equaling out to $15 per week. Since the bike costs $155.75, you subtract your $30, coming out to 125.75 then you divide it by 15 which is 8 days

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.
Alex777 [14]

Answer:

Nico, Raj and Sandra are correct

Step-by-step explanation:

we have

\frac{2}{5}(5+x)=8

<em>Method 1</em>

Solve for x

That means ----> isolate the variable x

we have

\frac{2}{5}(5+x)=8

Multiply by 5/2 both sides

(\frac{5}{2})\frac{2}{5}(5+x)=(\frac{5}{2})8

5+x=20

subtract 6 both sides

5+x-5=20-5

x=15

<em>Method 2</em>

Solve for x

That means ----> isolate the variable x

we have

\frac{2}{5}(5+x)=8

Multiply by 1/2 both sides

(\frac{1}{2})\frac{2}{5}(5+x)=(\frac{1}{2})8

\frac{1}{5}(5+x)=4

Multiply by 5 both sides

(5)\frac{1}{5}(5+x)=(5)4

5+x=20

subtract 6 both sides

5+x-5=20-5

x=15

<em>Method 3</em>

Solve for x

That means ----> isolate the variable x

we have

\frac{2}{5}(5+x)=8

Apply distributive property left side

\frac{2}{5}(5)+\frac{2}{5}(x)=8

2+\frac{2}{5}(x)=8

subtract 2 both sides

2+\frac{2}{5}(x)-2=8-2

\frac{2}{5}(x)=6

Multiply by 5/2 both sides

(\frac{5}{2})\frac{2}{5}(x)=(\frac{5}{2})6

x=15

therefore

Nico, Raj and Sandra are correct
