Answer:

-4

Step-by-step explanation:

2x + 3y = -14

x - y = 3

Multiply the second equation by -2 to eliminate x

2x + 3y = -14

-2x +2 y = -6

-----------------------

    5y = -20

Divide by 5

5y/5 = -20/5

y = -4

What is the value of 3 to the power 2 over 3 to the power 4?
Tanzania [10]

3^2/3^4

To find the answer, we can use this equation:

a^m / a^n = a^m - n

We can now just use 2 - 4, which equals -2.

Now we have 3^-2

3^-2 in decimal form is 0.11111, which equal to 1/9

The sum of three consecutive even numbers is 438. What is the 2nd number?
denis-greek [22]

First number = x

Second number = x + 2

Third number = x + 4

X + x +2 + x + 4 = 438

Simplify:

3x + 6 = 438

Subtract 3 from both sides

3x = 432

Divide both sides by 3

X = 144

The second number is 144 + 2 = 146

Dirk opened up a savings account with $600. At a yearly interest rate of 5 percent that is compounded monthly, how much interest
gladu [14]

Answer:

Hence final answer is $15.17

Step-by-step explanation:

Given that Dirk opened up a savings account with $600.

So P=$600

"At a yearly interest rate of 5 percent"

Means r=5% = 0.05

"compounded monthly" means n=12

i= monthly rate of interest = r/n=0.05/12

"how much interest will Dirk earn in six months." means find Interest when time is 6 months


Plug these values into compound interest formula:

A=P\left(1+i\right)^t

A=600\left(1+\frac{0.05}{12}\right)^6

A=600\left(1+0.00417\right)^6

A=600\left(1.00417\right)^6

A=600\left(1.02528228828\right)

A=615.169372966

which is approx

A=615.17

Now interest earned will be difference of A and P

Interest =A-P=615.17-600=$15.17

Hence final answer is $15.17

Ray is constructing a flowerbed for the zoo and wants to
faust18 [17]

Answer:

Option (3)

Step-by-step explanation:

Since, flowerbed is in the shape of a right triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(Hypotenuse)² = (12)² + (12)²

(Hypotenuse)² = 144 + 144

Hypotenuse = √288

Hypotenuse = 16.97

                     ≈ 17 ft

Perimeter of the triangle = Sum of the measures of three sides of the triangle

= 12 + 12 + 17

= 41 ft

Therefore, Option (3) will be the correct option.
