In which direction will this parabola open? x=53(y+17)^2-41

1 answer:

8 0

$x=53(y+17)^2-41\\
x=53(y^2+34y+289)-41\\
x=53y^2+1802y+15317-41\\
x=53y^2+1802y+15276$

As a>0 so the concavity (open) of the parable is to the right.

The directions: Write an equation in point-slope form of the line that passes through the given point and has the given slope m.

guajiro [1.7K]

Point slope form y- y1 = m(x- x1) coordinates are (2,1) m=2

so the equation becomes y-1= 2(x-2)

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9

castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

${a}^{2} = {b}^{2} + {c}^{2}$

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

${10}^{2} = {5}^{2} + {x}^{2}$

${x}^{2} = {10}^{2} - {5}^{2}$

${x}^{2} = 100 - 25$

${x}^{2} = 75$

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you

A system of equations is shown below. Find the solution by using substitution.

ASHA 777 [7]

Answer:

a) $(-2, 0)$

Step-by-step explanation:

x + 2 = 3x + 6

-3x - 3x

___________

−2x + 2 = 6

- 2 - 2

_________

4 = −2x

_ ___

−2 −2

$-2 = x$ [Plug this back into both equations above to get the y-coordinate of 0]; $0 = y$

I am joyous to assist you anytime.

Answer:

Step-by-step explanation:

Reasoning A store sells packages of comic books with a poster. A poster and 5 comics cost $13.99. A poster and 12 comics cost $20.99. Write a linear function rule that models the cost y of a package containing any number x of comic books. Suppose another store sells a similar package, modeled by a linear function rule with initial value $. Use pencil and paper. Explain which store has the better deal. The linear function rule is y nothing.
