Step-by-step explanation:

Step 1: Define

3.6y = 1.6y + 24

Step 2: Solve for y

[Subtraction Property of Equality] Subtract 1.6y on both sides:                  2y = 24[Division Property of Equality] Divide 2 on both sides:                                y = 12

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Substitute in y:                                                                                                3.6(12) = 1.6(12) + 24Multiply:                                                                                                           43.2 = 19.2 + 24Add:                                                                                                                 43.2 = 43.2

Here we have 43.2 does indeed equal 43.2.

∴ y = 12 is the solution to the equation.

Step-by-step explanation:

When you multiply exponents of the same base (variable), add the exponents.

1. The exponents are 12 - 4 + 6 = 14 or c^14

When you divide exponents of the same base, subtract them.

2. 8 - 2 = 6 or c^6

When you raise a power to a power, you multiply the exponents.

3. 4 * 5 = 20 or c^20

When a number is raised to a negative exponent it can be re written like this x^-n = 1/x^n.

4. x^-2 * y / x^4 * y^-1; using the above information, rewrite everything to have positive exponents. If the negative exponent is in the denominator, then it becomes x^n/1

y * y / x^2 * x^4 ; then just add your exponents to simplify

y^2 / x^6

As we said before, a power raised to a power is exponent x exponent.

5. (a^2 * b) ^-1 / (a^-3 * b^2)^-1 ; as before a power raised to a power, multiply the powers.

a^-2 * b-1 / a^3 * b^-2 rewrite this as before, inverting negative exponents. a^3 / a^2 * b^1 * b^2 = a^3 / a^2 * b^3

Simolifynthe new expression to reduce the a variable by subtracting the bottom a^2 from the top a^3 and are left with

a / b^3

Work number 6 like 5, no negative exponents, so there won't be any inversions. Just multiply the outside power times every exponent, then do the division by subtracting exponents of like bases.

When figuring out the problems with constants, treat them like the variables. In number 7 the 5a^2 when raised to the 2nd power would be 5^2*(a^2)^2 = 25 a^4

(x, y) = (1, -9)

Step-by-step explanation:

-8x-6y = 46

By substituting the value of y (first equation) into the second equation, we get,

-8x - 6*(-9x) = 46

-8x + 54x = 46

46x = 46

x = 1.

What is a parabola?

In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point and a line.

Given

The equation of a parabola is x = [tex]\frac{1}{4 \left(f - h\right)} \left(y - k\right)^{2} + h[/tex], where (h,k) is the vertex and (f,k) is the focus.

Thus, h = 0 k = 5, f = 3/2

The standard form is x = [tex]\frac{y^{2}}{6} - \frac{5 y}{3} + \frac{25}{6}x[/tex]

The general form is - 6 x + y² - 10 y + 25 = 0

The vertex form is x = [tex]\frac{\left(y - 5\right)^{2}}{6}[/tex]

The directrix is x = d

To find d, use the fact that the distance from the focus to the vertex is the same as the distance from the vertex to the directrix: [tex]0 - \frac{3}{2} = d - 0[/tex]

Thus, the directrix is x = - 3/2

The axis of symmetry is the line perpendicular to the directrix that passes through the vertex and the focus: y = 5

The focal length is the distance between the focus and the vertex: 3/2

The length of the latus rectum is four times the distance between the vertex and the focus: 6.

The eccentricity of a parabola is always 1.

1 1/3 needs to be turned into a improper fraction. 1 1/3=4/3.

Now we can do 4/3-5/6 but, the denominator has to be the same. We can make them 8/6-5/6.

*(Whatever happens to the denominator, has to happen to the numerator.)

8/6-5/6=3/6. Typically, the answer could be 3/6 but you could also simplify it to 1/2.

So, the answer would be 1/2.

Working together, two ants named Aran and Beatrice can build an ant hill in 10 hours. Aran and Charlie can build the ant hill in 12 hours. Beatrice and Charlie can build the ant hill in 15 hours. How long, in hours, will it take to build the ant hill if Aran, Beatrice, and Charlie work together?

Answers

Here we have a problem of rates of work, we want to know how long will take the 3 ants to build an ant hill if they work together.

We will find that working together, they need to work for 8 hours.

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

Let's start by defining the variables that we will use:

A = rate at which Aran worksB = rate at which Beatrice works.C = rate at which Charlie works.

Now let's see the given information:

"Aran and Beatrice can build an ant hill in 10 hours"

This can be written as:

(A + B)*10 h = 1 ant hill

"Aran and Charlie can build the ant hill in 12 hours"

This can be written as:

(A + C)*12 h = 1 ant hill

"Beatrice and Charlie can build the ant hill in 15 hours"

This can be written as:

(B + C)*15 h = 1 ant hill.

Then we have 3 equations:

[tex](A + B)*10 h = 1[/tex]

[tex](A + C)*12 h = 1[/tex]

[tex](B + C)*15 h = 1[/tex]

Where for commodity, I removed the "ant hill" unit.

Now we need to solve this system of equations, to do it, we need to isolate one variable in one of the equations and then replace it on another equation.

I will isolate A in the first equation:

[tex]A = \frac{1}{10h} - B[/tex]

Now we can replace it in the second equation to get:

[tex](\frac{1}{10h} - B + C)*12h = 1[/tex]

Now we can isolate C in the last equation to get:

[tex]C = \frac{1}{15h} - B[/tex]

Replacing that in the above equation we get:

[tex](\frac{1}{10h} - B + \frac{1}{15h} - B)*12h = 1\\\\\frac{1}{6h} - \frac{1}{12h}= 2*B\\\\\frac{1}{2}*\frac{1}{12h} = \frac{1}{24h} = B[/tex]

This means that Beatrice alone would construct the hill in 24 hours.

Now that we know the value of B, we can use:

[tex]C = \frac{1}{15h} - B = \frac{1}{15h} - \frac{1}{24h} = \frac{1}{40h}[/tex]

This means that Charlie needs 40 hours to finish the hill alone.

Finally, we can use [tex]A = \frac{1}{10h} - B[/tex] to find the value of A:

[tex]A = \frac{1}{10h} - B = \frac{1}{10h} - \frac{1}{24h} = \frac{7}{120h}[/tex]

Now if the 3 ants work together, the total rate at which they work is:

[tex](A + B + C) = (\frac{7}{120h} + \frac{1}{40h} + \frac{1}{24h} ) = 0.125 h^{-1}[/tex]

This means that they need to work for the inverse of that rate

[tex]\frac{1}{0.125h^{-1}} = 8h[/tex]

Working together, they need to work for 8 hours to complete an ant hill

True or False: If a quadratic equation cannot be factored, then it doesn't have any solutions.​

Answers

If a quadratic equation cannot be factored then it will have at least one imaginary solution.

In simpler terms, the answer you’re looking for is false :)

The given statement is false because a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

What is a quadratic equation?

The quadratic equation is defined as a function containing the highest power of a variable is two.

A quadratic equation is a type of polynomial equation that can be written in the form ax² + bx + c = 0, where a, b, and c are constants and x is a variable.

If a quadratic equation cannot be factored, it does not mean that it does not have any solutions.

A quadratic equation may have no solutions if the discriminant, which is the quantity b² - 4ac, is less than zero.

In this case, the quadratic equation has no real solutions, as the solutions would be complex numbers.

However, if the discriminant is equal to zero, the quadratic equation has one solution, which is the value of x that makes the equation equal to zero. If the discriminant is greater than zero, the quadratic equation has two solutions, which are the values of x that make the equation equal to zero.

In summary, a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

Thus, the given statement is false.
