Marcos had 15 coins in nickels and quarters. He had 3 more quarters than nickels. He wrote a system of equations to represent th

hodyreva [135]

Answer:

There are 6 coins in nickels and 9 coins in quarters.

Step-by-step explanation:

Now, to find the solution.

According to question:

The number of nickels = $x$ .

The number of quarters = $y.$

So, the total number of coins:

$x+y=15.$

He had 3 more quarters than nickels.

Thus,

$y=x+3$ .....(1)

Now, to get the solution:

$x+y=15$

Substituting the equation (1):

$x+(x+3)=15$

$x+x+3=15$

$2x+3=15$

Subtracting both sides by 3 we get:

$2x=12$

Dividing both sides by 2 we get:

$x=6.$

The number of nickels = 6.

Now, substituting the value of $x$ in equation (1):

$y=x+3\\\\y=6+3\\\\y=9.$

The number of quarters = 9.

Thus, there are 6 coins in nickels and 9 coins in quarters.

Melanie invested $5,500 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawa

Phantasy [73]

Answer:

$A=\$11,748.76$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=11\ years\\ P=\$5,500\\ r=6.9\%=6.9/100=0.069$

substitute in the formula above

$A=5,500(e)^{0.069*11}$

$A=5,500(e)^{0.759}$

$A=\$11,748.76$

(6, -12). (15. -3) Find the slope

Allisa [31]

Answer:

The slope is 1.

Step-by-step explanation:

A first order function has the following format

$y = ax + b$

In which a is the slope

(6, -12).

This means that when $x = 6, y = -12$

$y = ax + b$

$-12 = 6a + b$

(15. -3)

This means that when $x = 15, y = -3$

$y = ax + b$

$-3 = 15a + b$

We have to solve the following system of equations:

$-12 = 6a + b$

$-3 = 15a + b$

We have to find a

In the second equation i will write as:

$b = -3 - 15a$

Replacing in the first

$-12 = 6a + b$

$-12 = 6a - 3 - 15a$

$-9 = -9a$

$9a = 9$

$a = \frac{9}{9}$

$a = 1$

The slope is 1.
