Answer:

y - 3 = a(x + 1)^2

Step-by-step explanation:

The vertex equation of a vertical parabola is:

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

If the vertex is at (-1, 3), then the equation becomes:

y - 3 = a(x + 1)^2, where a is a constant.

Next time, would you please share the answer choices.  Thank you.

Which equation describes a line parallel<br> to y= 4x+ 5 through point (-2, 1)?
Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

\large\boxed{y - y_1 = m(x - x_1)}

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)

Simplify:

y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}

-3x(x+8)+x+2(9-x-x^2) please show solving steps
Flauer [41]

Answer:

-5x^2 - 25x + 18

Step-by-step explanation:

-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 )  ( original equation )

-3x^2 - 24x + x + 18 - 2x - 2x^2   ( distribute )

-3x^2 - 2x^2 - 24x + x - 2x + 18   ( order them based on the variables . )

( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 )    ( just separated them not a part of solving !! )

-5x^2 - 25x + 18    ( solved , and the answer :) )

Hope its helps !!!

P (a) =2/5 p(b)=1/4 ( a and b=1/25I did two events independent or dependent please help
juin [17]

we have

p (a) =2/5 p(b)=1/4 ( a and b=1/25

Remember that

we know that for two independent events A,B.

⇒ P(A∩B)=P(A)*P(B)

we have

P(A)=2/5 and P(B)=1/4

so

P(A∩B)=(2/5)*(1/4)=2/20=1/10

that means

<h2>events are dependent</h2>
