Nick invests $3,500 in an account earning 11% interest compounded annually. Krista invests $4,000 in an account earning 4% interest compounded annually. Who will have more money in their account after 2 years? How much more?

Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.

Subtract 9a from both sides to get a on the left side of the equation.

5 + 5a = -5

Subtract 5 from both sides of the equation to isolate the term with a.

5a = -10

Divide both sides of the equation by 5 to solve for a.

a = -2

The result to the equation is a = -2.

To break for a in the equation 5 + 14a = 9a - 5, we can start by simplifying both sides of the equation.

Adding 5 to both sides

5 + 14a + 5 = 9a - 5 + 5

10 + 14a = 9a

Next, we can insulate the variable a by abating 9a from both sides

14a - 9a + 10 = 9a - 9a

5a + 10 = 0

To break for a, we'll abate 10 from both sides

5a + 10 - 10 = 0 - 10

5a = -10

Eventually, we divide both sides by 5 to break for a

5a/ 5 = -10/ 5

a = -2

Thus, the result to the equation is a = -2.

(A) j || k by the converse of the same-side interior angle Theorem is your answer

Note that " j || k" means that line j & k are parallel (True)

Note that both ∠1 & ∠2 are on the same side, and that they are located inside the parallelogram produced by the transversal lines (Same Side - Interior Angle Theorem)

Therefore, (A) is your answer

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

~Rise Above the Ordinary

Lines are parallel if they have the same slope, not necessarily if the sum of their angles equals to 180.

The statement 'm1 + m2 = 180' typically holds true for two lines that are straight, where m1 and m2 are the angles measured from each line to a common line. If the sum of m1 and m2 adds up to 180º, the lines are supplementary, meaning they add up to form a straight line. However, they are not parallel.

In the context of lines that are parallel, they would have the same slope, but not necessarily the same angle. For instance, in a coordinate plane, the lines y = 4x + 1 and y = 4x - 3 are parallel because they have the same slope (4), but their y-intercepts are different.

If you want to solve this analytically, set the difference in y-values equal to zero and solve the resulting quadratic in the usual way. This will give the x-value at which the y-values are equal. (After we find x, we still need to find y.)

... y - y = 0

... x² -2x +9 -4x = 0

... x² -6x +9 = 0 . . . . . . collect terms. Recognize this as a perfect square.

... (x -3)² = 0

... x = 3 is the solution to this

... y = 4x = 4·3 = 12

The point on each of the given curves is (x, y) = (3, 12). The line is tangent to the parabola there, so there is only one point of intersection.

The line y = 4x and the parabola y = x^2 - 2x + 9 intersect at the point (3, 12).

To find the intersection points of the line y = 4x and the parabola y = x^2 - 2x + 9, we set the two equations equal to each other and solve for x. Hence the equation to solve is 4x = x^2 - 2x + 9. Rearranging this gives the quadratic equation x^2 - 6x + 9 = 0. This factors to (x - 3)^2 = 0, so x = 3 is the only solution, meaning the line and the parabola intersect at x = 3. Substituting x = 3 back into either the line or parabola equation gives y = 12, so the point of intersection is (3, 12).

Hello!

The function f/g means that that f(x) is written in the numerator and g(x) is written in the denominator because we are dividing the functions f(x) and g(x). (f/g = f(x)/g(x))

f(x)/g(x) is shown as: (3x - 6)/(x - 2).

The function shown above can be factored before we find the domain, since the greatest common factor of the numerator is 3.

f(x)/g(x) = 3(x - 2)/(x - 2)

f(x)/g(x) = 3

The function y = 3 is a horizontal line, so it has a domain of all real numbers.

Therefore, f/g is 3, and its domain is all real numbers, which is choice D.

Final answer:

The quotient of the functions f(x) = 3x - 6 and g(x) = x - 2 is 3. The domain of this quotient function is all real numbers except x = 2.

Explanation:

To find the quotient of the functions f(x) = 3x - 6 and g(x) = x - 2, we divide f(x) by g(x):

f/g = (3x - 6) / (x - 2).

Simplifying the expression:

f/g = 3(x - 2) / (x - 2).

Since (x - 2) is a common factor in both the numerator and the denominator, we can cancel it out as long as x is not equal to 2 (since division by zero is undefined):

f/g = 3; for all x ≠ 2.

Therefore, the quotient of f and g is 3, and the domain of this quotient function is all real numbers except x = 2.

Where is the question?

If you're referring to factorials, then,

6! = 6*5*4*3*2*1 = 720

You start with 6 and count your way down to 1, multiplying along the way.

Since there's a negative in front of the parenthesis, it switches the values inside. So that it's -2h+18=7h. h = 2

Final answer:

If we want to plot the graph of the equation y = -56x - 4, we can select two points on the line by choosing arbitrary values for x and then calculating the corresponding y-values.

Step-by-step explanation:

Let's choose x = 0 and x = 1 for simplicity:

1. When x = 0:

- Substitute x = 0 into the equation: y = -56(0) - 4

- Simplify the expression: y = 0 - 4 = -4

- So, the first point is (0, -4).

2. When x = 1:

- Substitute x = 1 into the equation: y = -56(1) - 4

- Simplify the expression: y = -56 - 4 = -60

- So, the second point is (1, -60).

Now we have two points on the line: (0, -4) and (1, -60). We can plot these points on a coordinate plane and draw a straight line passing through them to graph the equation y = -56x - 4.

Answer:

 729 is a perfect cube. The number whose cube is 729 is 9.

Explanation:

 Let us find the cubes of natural numbers from starting

     1 x 1 x 1 = 1

     2 x 2 x 2 = 8

     3 x 3 x 3 = 27

     4 x 4 x 4 = 64

     5 x 5 x 5 = 125

     6 x 6 x 6 = 216

     7 x 7 x 7 = 343

     8 x 8 x 8 = 512

     9 x 9 x 9 = 729

    10 x 10 x 10 = 1000

So we got that 729 is the cube of 9, so 729 is a perfect cube.

The number whose cube is 729 is 9.

Final answer:

Yes, 729 is a perfect cube and the number whose cube is 729 is 9.

Explanation:

Yes, 729 is a perfect cube.

To find the number whose cube is 729, we can take the cube root of 729, which is denoted as ∛729.

∛729 = 9

Therefore, the number whose cube is 729 is 9.

You did everything right all the way up to one small thing at the end.  When you moved the decimal to the left and made 10.35 into 1.035, you would need to make the exponent an 11.  Raising the exponent will show that you have moved the decimal more than the original problem started with.

So a multivariate polynomial expression are [tex]\frac{7y^{2} +9x}{4}[/tex] and 6y²+ 5x.

Because in the other options:

We have a Radical of an Irrational number[tex]\sqrt{3} =3^{\frac{1}{3}}[/tex] times x (2nd option) what does not configure a polynomial.

Final answer:

To create an alloy with 4.9 lb of zinc based on the nickel to zinc ratio of 2:7, about 1.4 pounds of nickel is required.

Explanation:

To determine how many pounds of nickel have to be used to create an alloy that contains 4.9 lb of zinc, we must first understand the given ratio of nickel to zinc to copper in the alloy, which is 2:7:9. Since zinc's ratio is 7 and we have 4.9 lb of it, we can calculate the amount of nickel by setting up a proportion.

We use the proportion 2/7 = x/4.9, where x represents the pounds of nickel. By cross-multiplying and solving for x, we get x = (2 * 4.9) / 7, which simplifies to x = 9.8 / 7. This gives us the result x ≈ 1.4 lb.

Therefore, to create an alloy with 4.9 lb of zinc, approximately 1.4 pounds of nickel are needed.

Answer:

 Total weight of the nuts bought by Dan =  5.4 kg

Explanation:

Number of packets of nuts bought by Dan = 24

Weight of each packet of nuts = 225g

 Total weight of the nuts bought by Dan = Number of packets of nuts bought by Dan * Weight of each packet of nuts

    Total weight of the nuts bought by Dan = 24 * 225 = 5400 g = 5400/1000 kg = 5.4 kg
