Answer: His usual average = 28.

Step-by-step explanation:

Let x = usual average at the basketball game tonight.

As per given,

[tex]\dfrac{x}{2}+10=24[/tex]

Subtract 10 from both sides , we get

[tex]\dfrac{x}{2}+10-10=24-10\\\\\Rightarrow\ \dfrac{x}{2}=14\\\\\Rightarrow\ x=14\times2=28[/tex]

Hence, his usual average = 28.

Answer:

Step-by-step explanation:

Angles opposite congruent sides are congruent, so base angles D and F of this isosceles triangle have the same measure:

  y = 55

__

The sum of angles in the triangle is 180°, so ...

  55° +(11x +4)° +55° = 180°

  11x = 66 . . . . . . . . divide by °, subtract 114

  x = 6 . . . . . . . . . . .divide by 11

The values of x and y are 6 and 55, respectively.

Answer:

Step-by-step explanation:

11/2=55/10

2=20/10

4/5=8/10

55+20+8/10=83/10

Answer:45

Step-by-step explanation:

Step-by-step explanation: First change the minus inside to plus a negative.

Now we can distribute the -8 through each

of the terms inside the set of parenthses.

So we have -8(2y) + -8(-3) or -16y + 24.

Answer: n is greater than or equals to 1, where n is an integer

Step-by-step explanation:

The domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Abraham is writing a recursive function for the geometric sequence:

24, 12, 6,3,

The above sequence is a geometric progression.

The first term geometric progression is 24

s(1) = 24

s(n) = s(n-1)(1/2)

The nth term of the geometric progression:

The common ratio = 12/24 = 1/2

s(n) = s(n-1)(1/2)

Here n should be an integer number that is greater than 1

n ≥ 1 where n is an integer.

Thus, the domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.

Answer:

3C + 3D = 12x² -12x + 30

Step-by-step explanation:

Given

To determine

The expression is given by

3C + 3D

substituting C = x² + 7 and D = 3x² - 4x + 3

= 3(x² + 7) + 3(3x² - 4x + 3)

= 3x² + 21 + 9x² - 12x + 9

= 12x² -12x + 30

Thus, the expression in standard form is:

3C + 3D = 12x² -12x + 30

The solutions from least to greatest are lesser x = -2 and greater x = 2/3 for the equation (2x +4)(3x -2)=0

An equation is collection of two or more expressions with an Equal sign

The given equation is (2x +4)(3x -2)=0

To find the solutions, we set each factor equal to zero and solve for x

2x + 4 = 0

Subtract 4 from both sides

2x = -4

Divide both sides by 2

x = -2

Now 3x - 2 = 0

Add 2 on both sides

3x = 2

Divide both sides by 3

x = 2/3

Therefore, the solutions from least to greatest are lesser x = -2 and greater x = 2/3

Equation of circle G: [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

"An equation of a circle with center (p, q) and radius r is:[tex](x-p)^{2}+ (y-q)^{2}=r^{2}[/tex] "

"The coordinates of the midpoint M of two points (a, b) and (x, y) :

[tex]M(\frac{a+x}{2} ,\frac{b+y}{2} )[/tex] "

"The distance between two coordinate points (a, b), (m, n):

[tex]d=\sqrt{(n-b)^{2} +(m-a)^{2} }[/tex] "

"A diameter of a circle is the straight line that from one side of a circle to other side and passes through the center."

For given question,

The line segment connecting the two points B(-4,4) and D (10,4) is a diameter of the circle.

This means, the midpoint of the diameter BD would be the center of a circle G.

Let M represents the center of the circle.

First we find the coordinates of the center of the circle.

Using midpoint formula,

⇒ M = [tex](\frac{-4+10}{2} ,\frac{4+4}{2} )[/tex]

⇒ M = (6/2 , 8/2)

⇒ M = [tex](3,4)[/tex]

Now, we find the distance between points B(-4,4) and D (10,4) to determine the diameter of a circle G.

Using distance formula,

⇒ [tex]d=\sqrt{(4-4)^{2} +(10-(-4))^{2} }[/tex]

⇒ [tex]d=\sqrt{0+(14)^{2} }[/tex]

⇒ [tex]d=14[/tex] units

So, the radius of the circle r would be,

r = d/2

⇒ r = 14 / 2

⇒ r = 7 units

Now, we find the equation of circle with center M(3, 4) and radius r = 7 units.

Using center - radius form equation of circle would be,

[tex](x-3)^{2} + (y-4)^{2} = 7^{2}[/tex]

⇒ [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

Therefore, option (A) is the correct answer.
