Use Distributive Property: -8 (2y - 3)
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.

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

Points B(-4,4) and D (10,4) lie on circle G. The line segment connecting the two points is a diameter of the circle.
Which equation represents circle G?
A. (x – 3)2 + (y – 4)2 = 49
O B. (x - 10)2 + (y - 4)2 = 49
O C (x+3)2 + (1 – 4)2 = 49
D. (x+4)2 + (y – 4)2 = 49
Equation of circle G: [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

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

What is diameter of circle?"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.

Abraham is writing a recursive function for the geometric sequence:
24, 12, 6,3,
He comes up with:
s(1) = 24
s(n) = s(n-1)
What domain should Abraham use for s so it generates the sequence
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.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
The question is incomplete.

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.

If C=x^{2}+7C=x 2 +7 and D=3x^{2}-4x+3,D=3x 2 −4x+3, find an expression that equals 3C+3D3C+3D in standard form.
Answer:
3C + 3D = 12x² -12x + 30
Step-by-step explanation:
Given
C = x² + 7D = 3x² - 4x + 3To determine
3C + 3DThe 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

Joe scored 10 more than half his normal average at the basketball game tonight. If he scored 24 times, what is his usual average?
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.
