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.

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.

Answer:

The independent variable (IV) is the amount of hamburgers

Step-by-step explanation:

The amount of hamburgers influence the sale amount.

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

Answer:

The answer is C, 40.32

Step-by-step explanation:

If you put 6.25 in your calculator times 40.32% you get 2.52. Then you add the 2.52 to 6.25 to get 8.77.

Answer:

The answer is 1/2.

Step-by-step explanation:

1 1/3-5/6=

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.

Hopefully this helps you and sorry if it doesn't.

Answer:

Tamu burnt 5.66 calories per minute.

Step-by-step explanation:

Tamu ran for 30 minutes.

Calories burnt by Tamu = 170 calories

Unit rate = [tex]\frac{Calories\ burnt}{Time}[/tex]

Unit rate = [tex]\frac{170}{30}[/tex]

Unit rate = 5.66 calories per minute

Therefore,

Tamu burnt 5.66 calories per minute.

Answer:

F

Step-by-step explanation:

to find x coordinate for midpoint, add both the x coordinates then divide by two. we get x=1

to find y coordinate for midpoint, add both the y coordinates then divide by two. we get y=2

so the coordinates of midpoint is (1,2), which is F

The  equation has a vertex at (0, 5) and focus of (three-halves, 5) is,

- 6 x + y²- 10 y + 25 = 0

−6x+y² −10y+25=0

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.

Answer:

D. 2/3

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

y = -9x

-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.

So, y = -9
