The elimination method is a method for solving systems of linear equations.

The method of elimination  consists of removing the same variable from two equations and then finding the value of the other variable that is not eliminated after taking the difference between the two equations.

An equation of the form Ax By = C. Here x and y are variables and A, B and C are constants.

To solve the variables of the given equations by elimination method Let's look at a short comprehensible example.

2x + y = 7 ------> (1)

x + y = 5 -------> (2)

To eliminate 'y', subtract (1) - (2),

2x + y - x - y = 7 - 5

x = 2

Substitute x = 2 in equation(1),

2(2) + y = 7

4 + y = 7

y = 3

Therefore, x = 2, y = 3

Given that the product has a 0 in the thousands place, the value of k is C. 4.

The product is the result of multiplying two or more numbers together.

The product is the result of multiplication, which is one of the mathematical operators, including addition, subtraction, division, exponentiation, and modulus operations.

Product of 13,462 and 798k = 13,462 x 798 x k

= 10,742,676k

K = variable

If k = 1, the product of 10,742,676k = 10,742,676, the nearest thousand = 10,743,000

If k = 2, the product of 10,742,676k = 21,485,352, the nearest thousand = 21,485,000.

If k = 4, the product of 10,742,676k = 42,970,704, the nearest thousand = 42,970,000.

If k = 7, the product of 10,742,676k = 75,198,732, the nearest thousand = 75,199,000.

If k = 9, the product of 10,742,676k = 96,684,084, the nearest thousand = 96,684,000.

Thus, given that the product has a 0 in the thousands place, the value of k is C. 4.

a) To save enough funds to purchase the car in 2.5 years, monthly deposits of $373.69 are required, while weekly deposits of $86.21 are needed.

b) With annual deposits of $2,000, it will take approximately 5 years to accumulate sufficient funds to purchase the car. For borrowing options, under Option 1, the monthly installment amount is $349.56, which reduces to $291.55 with a $1,800 lump sum contribution from parents. Under Option 2, the monthly installment amount is $237.63 for the first 36 months, doubling thereafter.

a) To calculate the minimum required monthly savings, we use the future value formula with monthly compounding: \($10,000 = PMT * ((1 + 0.06/12)^(2.5*12) - 1) / (0.06/12)\). Solving for PMT, the monthly deposit required is approximately $373.69.

b) Similarly, for weekly deposits, we use the future value formula with weekly compounding: \($10,000 = PMT * ((1 + 0.06/52)^(2.5*52) - 1) / (0.06/52)\). Solving for PMT, the weekly deposit required is approximately $86.21.

c) Using the future value formula for annual deposits: \($10,000 = $2,000 * ((1 + 0.06)^t - 1) / 0.06\). Solving for t, the time required to accumulate $10,000, we find it will take approximately 5 years.

d) For Option 1, the monthly installment amount can be calculated using the present value formula: \($13,000 = X * (1 - (1 + 0.06/12)^-30) / (0.06/12).\) Solving for X, the monthly installment amount is approximately $349.56.

e) With a lump sum contribution of $1,800, the remaining loan amount becomes $13,000 - $1,800 = $11,200. Using the same formula as in (d), the new monthly installment amount is approximately $291.55.

f) For Option 2, the monthly installment amount during the first 36 months is $Y. After 36 months, the monthly installment amount doubles. Using the present value formula: \($13,000 = Y * (1 - (1 + 0.06/12)^-36) / (0.06/12) + 2Y * (1 - (1 + 0.06/12)^-30) / (0.06/12)\). Solving for Y, the monthly installment amount is approximately $237.63.

We know that:

Work:

        4x + y = 73 cards

        9(4x + y = 73 cards)

        36x + 9y = 73 x 9 cards

This means that 1 premade deck is worth 37 cards. Now, let's substitute the value of y into the first equation to find x.

Hence, one booster pack is worth 9 cards and one premade deck is worth 37 cards.

Answer: When x=2 and z = 1, then the value of y =4.

Step-by-step explanation:

Given: y varies directly as x and z i.e. \(y\ \alpha \ xz\)

\(y=k(xz)\)      (i) , where k is the proportionality constant.

Put  Y=40 ,x =5 and z = 4, then we get

\(40=k(5\times4)\\\\\Rightarrow\ k=\dfrac{40}{20}\\\\\Rightarrow\ k=2\)

Required equation: \(y=2(xz)\)  [Put value of k in (i)]

Now put x=2 and z = 1, then we get

\(y=2(2\times1)=2(2)=4\\\\\Rightarrow\ y=4\)

Hence, when x=2 and z = 1, then the value of y =4.

Answer:

a = -3

Step-by-step explanation:

Step 1:  Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:

5^a = 1/125

Step 2:  Take the log of both sides

log(5^a) = log(1/125)

Step 3:  According to the power rule of logs, we can bring a down and multiply it by log(5):

a * log(5) = log (1/125)

Step 4:  Divide both sides by log(5) to solve for a:

(a * log(5) = log(1/125)) / log(5)

a = -3

Optional 5:  We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:

5^-3 = 1/125

1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator

1/125 = 1/125

Answer:

The equation for the alternating current can be described by: y = 155 sin(120πt)

Where y is the voltage in volts (V) and t is the time in seconds (s).

To find the value of y when t = 1/90 s:

y = 155 sin(120π(1/90))

y ≈ 30.8 V

To approximate the value of t when y = 100 V for the first time, we need to solve the equation for t:

100 = 155 sin(120πt)

sin(120πt) = 100/155

t = arcsin(100/155)/(120π)

t ≈ 0.001 s

Therefore, the value of t when y = 100 V for the first time is approximately 0.001 seconds

Answer:

P = 5/12 = 0.42

Step-by-step explanation:

In the bucket we have:

3 small red blocks

5 small yellow blocks

5 large yellow blocks

7 large red blocks

Ok, now we know that we draw one of the large blocks, and we want to find the probability that the block is yellow.

The probability will be equal to the quotient between the number of larger yellow blocks (5) and the total number of large blocks (5 + 7 = 12) (we only care for the large blocks because we start by assuming that we draw one of these)

Then the probability is:

P = 5/12 = 0.42

end behavior on left: function goes to + infinity

end behavior on the right: function goes to - infinity

Step-by-step explanation:

You look at the highest powered x term.

You look at the highest powered x-term which is - 3x^5. The polynomial will begin and end the same way a -x^5 curve begins and ends.

end behavior on the left side (as x approaches negative infinity), y values approach positive infinity. You can substitute negative values of x (-1, -5, -10, -100 . . .) in - 3x^5 and you will get increasing positive values for y as you use x values that approach negative infinity).

end behavior on the right side (as x approaches positive infinity), y values approach negative infinity. Substitute positive values for x (1, 10, 100, 1,000 . . .) in - 3x^5 and you will get decreasing negative values for y.

Step-by-step explanation:

X is the same of H that is you answer

The rate of the square increasing when the area is 16 cm² is 64 cm²/s. The result is obtained by using basic derivative rules.

The rate of a square increasing can be counted by the derivative of the area of the square as a function of time.

dA/dt = 2s ds/dt

Where s is side length.

If each side of a square is increasing at a rate of 8 cm/s, what is the rate of the square increasing when the area is 16 cm²?

We have the side of the square as the function of time.

ds/dt = 8 cm/s

When the area is 16 cm², the side length is

A = s²

16 = s²

s = √16

s = 4 cm

The rate of the square increasing is

dA/dt = 2s ds/dt

dA/dt = 2 × 4 × 8

dA/dt = 64 cm²/s

Hence, the rate of the square increasing when the area is 16 cm² is 64 cm²/s.
