Answer 1

Answer:

ANSWER:

Price of the stock after owning for 12 weeks is $12c, where c can be price per one week.

SOLUTION:

Given, the price of a particular stock is represented by the linear equation where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.

We need to find the price of the stock when this relationship continues, after it has been owned for 12 weeks?

As it is an linear equation, proportionality exists between x and y

y ∝ x

y = cx → ( 1 )

where, c is the proportionality constant.

Now, put x = 12 weeks to find the y value in (1).

y = c(12)

y = 12c

Hence, price of the stock after owning for 12 weeks is $12c, where c can be price per one week.

if it is $(3)/(3(4c+16))$ =2c+9, go to AAAAAA
if it is ( $(3)/(3)$ )(4c+16)=2c+9, go to BBBBB

AAAAAAAAA
$(3)/(3(4c+16))$ =2c+9
$(1)/(4c+16)$ =2c+9
times 4c+16 to both sides
1=(2c+9)(4c+16)
distribute
1=8c^2+68c+144
minus 1 both sides
0=8c^2+68c+143
use quadratic formula
c= $(-17- √(3) )/(4)$ or $(-17+ √(3) )/(4)$

BBBBBBBBBBBB
(3/3)(4c+16)=2c+9
1(4c+16)=2c+9
4c+16=2c+9
minus 2c both sides
2c+16=9
minus 16 both sides
2c=-7
divide both sides by 2
c=-7/2
c=-3.5

if it is $(3)/(3(4c+16))$ =2c+9,
c= $(-17- √(3) )/(4)$ or $(-17+ √(3) )/(4)$

if it is ( $(3)/(3)$ )(4c+16)=2c+9, c=-3.5

Acutly its really simple Let's solve your equation step-by-step.3/3(4c+16)=2c+9Step 1: Simplify both sides of the equation.3/3(4c+16)=2c+9Simplify: ((3/3)(4c)+(3/3)(16)=2c+9(Distribute)4c+16=2c+9Step 2: Subtract 2c from both sides.4c+16−2c=2c+9−2c2c+16=9Step 3: Subtract 16 from both sides.2c+16−16=9−162c=−7Step 4: Divide both sides by 2.2c/2=−7/2c=−7/2Answer:c=−7/2

Answer:

x =-2 and z =-4

Step-by-step explanation:

We need to solve the following systems of equation

-3x-2y+4z = -16 eq(1)

10x+10y-5z = 30 eq(2)

5x+7y+8z = -21 eq(3)

Multiply eq(1) with 10 and eq(2) with 3

-30x-20y+40z = -160

30x+30y-15z = 90

__________________

10y+25z = -70

Divide by 10

2y+5z = -14 eq(4)

Multiply eq(1) with 10 and eq(3) with 6

-30x-20y+40z = -160

30x+42y+48z = -126

__________________

22y+88z = -286

Divide by 11

2y+8z = -26 eq(5)

Subtract eq(4) and eq(5)

2y+5z = -14

2y+8z = -26

- - +

__________

-3z = 12

z = 12/-3

z = -4

Putting value of z in eq(4)

2y+5z = -14

2y +5(-4) = -14

2y = -14 +20

2y = 6

y = 3

Putting value of z and y in eq(1)

-3x-2y+4z = -16

-3x-2(3)+4(-4) = -16

-3x -6 -16 = -16

-3x = -16+16+6

-3x = 6

x = 6/-3

x = -2

What is the value of c in the equation y = 4x^2 -10x + c if the y-coordinate of the vertex is -7

Answers

Answer: $c=-(3)/(4)$

Step-by-step explanation:

Find the x-coordinate of the vertex with this formula:

$x=(-b)/(2a)$

In this case:

$a=4\nb=-10$

Substituting values, we get:

$x=(-(-10))/(2(4))=(5)/(4)$

Now we can substitute the coordinates of the vertex into the equation $y = 4x^2 -10x + c$ and then solve for "c".

Then:

$-7 = 4((5)/(4))^2 -10((5)/(4)) + c\n\n-7+(25)/(4)=c\n\nc=-(3)/(4)$

Answers

306/6 is 51 is you add one to one side and take away the other the six numbers become: 46, 48, 50, 52, 54, 56 as you added one to one side substituting the other you took away from, therefore the smallest would be 46.
