Answer:

AB=7

Step-by-step explanation:

(x-2)+(-15+2x)=10

x-2-15+2x=10

3x-17=10

3x=10+17

3x=27

x=27/3

x=9

AB=x-2=9-2=7

Explain how the graph of a quadratic function relates to the solutions of the related quadratic equation.
OleMash [197]

Answer:

The zeros of a quadratic function are the solutions of the related quadratic equation. If the graph of a quadratic function crosses the x-axis, there will be two real number solutions. If the graph of a quadratic function just touches the x-axis, there will be one unique real number, or double root, solution. If the graph of a quadratic function does not cross the x-axis, there will be no real number solution.

Match the three graphs to the function they represent ?
Mama L [17]

Suppose that a>b>1, then

a^x>b^x and \log_ax

Therefore, since 2<3<7, \log_2x>\log_3x>\log_7x.

Choose an arbitrary x>1. You have that a takes the greatest values at x, c takes the smallest value at x. Thus,

a>b>c and

  • a=\log_2x;
  • b=\log_3x;
  • c=\log_7x.

Answer: correct option is B.

The equation of a circle is given below.
BARSIC [14]

<u>Given</u>:

The equation of the circle is x^2+(y+4)^2=64

We need to determine the center and radius of the circle.

<u>Center</u>:

The general form of the equation of the circle is (x-h)^2+(y-k)^2=r^2

where (h,k) is the center of the circle and r is the radius.

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the center.

The given equation can be written as,

(x-0)^2+(y+4)^2=64

Comparing the two equations, we get;

(h,k) = (0,-4)

Therefore, the center of the circle is (0,-4)

<u>Radius:</u>

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the radius.

Hence, the given equation can be written as,

x^2+(y+4)^2=8^2

Comparing the two equation, we get;

r^2=8^2

 r=8

Thus, the radius of the circle is 8

Verizon [17]

The above question was not written properly

Complete Question

Everyone loved the Chocolate eclairs and they all got eaten during the party. Mr Watson friend, James, ate 6/8 of them if there were 16 of the chocolates, how many did James eat?

Answer:

12 chocolates

Step-by-step explanation:

From the above question, we know that

Total number of Chocolates = 16

The fraction of Chocolate that James ate = 6/8

Therefore, the amount of chocolates that James ate is calculated as:

= 6/8 of 16 chocolates

= 6/8 × 16 chocolates

= 12 chocolates

Therefore, James ate 12 chocolates.
