Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

Answer:

Step-by-step explanation:

and

, so this equation can also be written as

(

)

Since the bases are now the same, we can equate exponents to get

so that

(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).

Given the quadratic equation <img src="https://tex.z-dn.net/?f=y%20%3D%202%28x%20-1%29%5E%7B2%7D%20%2B%208" id="TexFormula1" tit

Answer:

Part 1) "a" value is $2$

Part 2) The vertex is the point $(1,8)$

Part 3) The equation of the axis of symmetry is $x=1$

Part 4) The vertex is a minimum

Part 5) The quadratic equation in standard form is $y=2x^{2}-4x+10$

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

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

where

(h,k) is the vertex of the parabola

if a > 0 then the parabola open upward (vertex is a minimum)

if a < 0 then the parabola open downward (vertex is a maximum)

The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

$x=h$

In this problem we have

$y=2(x-1)^{2}+8$ -----> this is the equation in vertex form of a vertical parabola

The value of $a=2$

a>0 then the parabola open upward (vertex is a minimum)

The vertex is the point $(1,8)$

$(h,k)=(1,8)$

The equation of the axis of symmetry is $x=1$

The equation of a vertical parabola in standard form is equal to

$y=ax^{2}+bx+c$

Convert vertex form in standard form

$y=2(x-1)^{2}+8$

$y=2(x^{2}-2x+1)+8$

$y=2x^{2}-4x+2+8$

$y=2x^{2}-4x+10$

see the attached figure to better understand the problem

Needing help, the secretary of the united states department of agriculture asked your teacher, "if a chicken-and-a-half can lay

Flura [38]

we are given that

3 chickens to lay 32 eggs

now, we can find number of eggs per chicken

number of eggs per chicken= (total eggs)/(total chicken)

so, we get

number of eggs per chicken is

$=\frac{32}{3}$

now, we can set up following

1.5 chicken : 1.5 eggs : 1.5 days

3 chickens : 3 eggs : 1.5 days

1 chicken : 1 egg : 1.5 days

Since, changing number of chicken won't affect time

time to lay eggs will always remain same

so,

for 1 chicken to lay $=\frac{32}{3}$ eggs

it takes

$=\frac{32}{3}*1.5 days$

$=16 days$ ..............Answer
