b = 4 or -3

Step-by-step explanation:

You mean this?;

b² - b - 12 = 0

Using quadratic formula (attached):

b = (1 ± (1 + 48)^1/2) ÷ 2 = (1 ± 7) ÷ 2 = 4 or -3

Answer:

12 servings

Step-by-step explanation:

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey?

From above question:

2.5 pounds of ground turkey = 5 servings

6 pounds of ground turkey = x

Cross Multiply

2.5 × x = 6 × 5

x = 6 × 5/2.5

x = 12 servings

Hence, 6 pounds of ground turkey can make 12 servings.

Completing the explanation.

The equation is

5x = 2.5y

where:

x = represent how many pounds of ground turkey he has = 6 pounds

y = to represent how many servings he can make

Hence,

5 × 6 = 2.5y

y = 5 × 6/2.5

y = 12 servings

Answer: The square root function f(x)=√x has domain [0,+∞) and the end behaviour is. as x→0 , f(x)→0. as x→∞ , f(x)→∞. Note: "end behavior"

Step-by-step explanation:

So, the sign of the leading coefficient is sufficient to predict the end behavior of the function. To predict the end-behavior of a polynomial function, first check whether the function is odd-degree or even-degree function and whether the leading coefficient is positive or negative.

The end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.

Option A is correct.

We have to find the end behavior of the given radical function.

To check end behavior, we have to check limit of function at x tends to infinity and x tends to minus infinity.

Given function are,

                   [tex]f(x)=-2\sqrt[3]{x+7}[/tex]

We can not put [tex]x=-\infty[/tex], because variable under square root must be greater than equal to zero.

When we check limit at [tex]x=\infty[/tex].

[tex]\lim_{x \to \infty} f(x)= \lim_{x \to \infty} -2\sqrt[3]{x+7}=-\infty[/tex]

Hence, the end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.

Answer:

C. y = 1/4x + 1/4

Step-by-step explanation:

Just did it on Edmentum and got it right

Answer:

C. y=1/4x+1/4

Step-by-step explanation:

Like the first path, this path will have a slope that is the opposite reciprocal of -4, the slope of the path passing through F(4,14) and G(7,2).

Substitute 1/4  and the coordinates of point G into slope-intercept form, and solve for b

Then, substitute 1/4 for m and 1/4  for b to find the equation of the line that’s perpendicular to the original path and passes through G(7,2)

Answer:

that would be 1

Step-by-step explanation:

if it was just 3 + 4 then it would be 7

but since it is -3  + 4

then it is just like subtracting 3 - 4 and that would be 1

Answer:

Point, line and plane

Step-by-step explanation:

Words are defined using other defined words or terms. However, these three terms are very difficult to find other words to describe. Without using other terms, we create circular definitions; thus these are called the "undefined terms" of geometry.

Answer:

y - 6 = 3(x + 2)

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Given: m(slope) = 3, (6, -2)

(x1, y1) = (6, -2)

Input the given values of the slope and the point into the equation for point-slope form:

y - (-2) = 3(x - 6)

y + 2 = 3(x - 6)

The equation written in point-slope form is: y + 2 = 3(x - 6)

Answer:

Yes.

Step-by-step explanation:

In order to check if an equation is true, plug in the corresponding values for x and y.

Coordinates are written as (x, y). So, x = 3 and y = 6.

Plug in these values to the equation.

6 = 2 * 3

Multiply 2 and 3 to simplify:

6 = 6

This shows that the equation is true when given (3, 6)

Answer:

The vertex of the quadratic function is:

[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=x^2+6x+16[/tex]

As the vertex of the form [tex]y=ax^2+bx+c[/tex] is defined as:

[tex]x_v=-\frac{b}{2a}[/tex]

As the quadratic function of parabola params are

[tex]a=1,\:b=6,\:c=16[/tex]

so

[tex]x_v=-\frac{b}{2a}[/tex]

[tex]x_v=-\frac{6}{2\cdot \:1}[/tex]

[tex]x_v=-3[/tex]

Putting [tex]x_v=-3[/tex] to determine [tex]y_v[/tex]

[tex]y_v=\left(-3\right)^2+6\left(-3\right)+16[/tex]

[tex]y_v=3^2-18+16[/tex]

[tex]y_v=9-2[/tex]

[tex]y_v=7[/tex]

Therefore, the vertex of the quadratic function is:

[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]

Step-by-step explanation:

Answer: 5.43 minutes

Step-by-step explanation:

Number of minutes for the drama group = 90 minutes

Number of times to practice the pirate scene = 4

Time taken to practice the pirate scene = 13

The number of minutes used for pirate scene will be:

= 4 × 13 = 52 minutes

The number of full times that the group can practice the mermaid scene will then be:

= (90 - 52) / 7

= 38 / 7

= 5.43 minutes

Answer:

Step-by-step explanation:

Each friend has 2 arms, right? So 6 friends with 2 arms would be 6 x 2. 6 x 2 = 12

each arm. well ever person had two arms. so one for each arm. so 1 x 2 x 6 would be 12. so 12 bracelet

Answer:

1 5/12

Step-by-step explanation:

first we have to convert the denominator(bottom number) to 12

6x2=12

Now we have to multiple 2 to the numerator(top number)

since we have to do the same to the top and bottom

5x2=10

now we add the fractions

7/12+ 10/12=17/12

now we simplify the fraction

17/12= 1 5/12

hopefully you understand how to do it.

Have a good day:)
