C(x)=x^2+6x+14 find vertex form

nalin [4]

Answer:

c(x)=(x+3)^2+5

Step-by-step explanation:

To complete the square, the same value needs to be added to both sides.

So, to complete the square x^2+6x+9=(x+3)^2 add 9 to the expression

C(x) =x^2 +6x + 9 + 14

Since 9 was added to the right-hand side also add 9 to the left-hand side

C(x) +9= x^2 +6x + 9 + 14

Using a^2 + 2ab + b^2=(a+b)^2, factor the expression

C(x)+9= (x+3)^2 +14

Move constant to the right-hand side and change its sign

C(x)=(x+3)^2 +14 - 9

Subtract the numbers

C(x)= (x+3)^2 +5

Jim has only dimes and nickels in his coin bank. He has 37 coins with a total value of $2.65.

guajiro [1.7K]

Answer:

Step-by-step explanation:

Let x represent the number of dimes and y represent the number of nickels. The total number of coins is 37; this gives us the equation

x+y = 37

Each dime is worth ten cents, or 0.10, and each nickel is worth five cents, or 0.05. The total amount of money is given by

0.10x+0.05y = 2.65

This gives us the system

$\left \{ {{x+y=37} \atop {0.10x+0.05y=2.65}} \right.$

To solve this, we will use substitution. We will isolate x in the first equation:

x+y=37

Subtract y from each side:

x+y-y = 37-y

x = 37-y

Substitute this into the second equation:

0.10(37-y)+0.05y = 2.65

Using the distributive property,

0.10(37)-0.10(y)+0.05y = 2.65

3.70-0.10y+0.05y = 2.65

Combining like terms,

3.70-0.05y = 2.65

Subtract 3.70 from each side,

3.70-0.05y-3.70 = 2.65-3.70

-0.05y = -1.05

Divide both sides by -0.05:

-0.05y/-0.05 = -1.05/-0.05

y = 21

There were 21 nickels.

If kevin makes c toys in m minutes, how many toys can he make per hour

mina [271]

Answer:

$\frac{60c}{m}$

Step-by-step explanation:

We can use the unity rule to solve this problem.

Number of toys made in m minutes = c

Number of toys made in 1 minute = $\frac{c}{m}$

Number of toys made in 60 minutes = $\frac{c}{m} \times 60 = \frac{60c}{m}$

Since 60 minutes = 1 hours, we can write:

Number of toys made in 1 hour = $\frac{60c}{m}$

Therefore, we can say that Kevin makes $\frac{60c}{m}$ toys per an hour.
