What is the expanded form of 4(7x+3)
Final answer:
The expanded form of 4(7x+3) is achieved by using the distributive property, resulting in the expression 28x + 12.
Explanation:
The expanded form of the algebraic expression 4(7x+3) involves distributing the 4 to both terms inside the parentheses. This is accomplished using the distributive property of multiplication over addition. The steps are as follows:
Multiply 4 by 7x to get 28x.
Multiply 4 by 3 to get 12.
Combine these products to express the expanded form.
Therefore, the expanded form of 4(7x+3) is 28x + 12.
As for evaluating complex expressions such as 2+x(−7+x(2+x(−8+x(−2+3x)))), you would begin by substituting the value of x and simplifying from the innermost parentheses outwards. However, this is a different exercise than simply expanding an algebraic expression.

For what value of x do expressions 2x+3 and 3x-6 have the same value?
Answer:
x = 9
Step-by-step explanation:
To find the value of x to make the 2 expressions equal, then equate them, that is
3x - 6 = 2x + 3 ( subtract 2x from both sides )
x - 6 = 3 ( add 6 to both sides )
x = 9
Then
3x - 6 = 3(9) - 6 = 27 - 6 = 21 and 2x + 3 = 2(9) + 3 = 18 + 3 = 21
find the value of x and the measure of the exterior angle
The measure of the angle x is 70 degrees because the sum of the two interior angles is equal to the exterior angle.

f(2/9) if f(x)=3x+1/3 x=2/9
Answer:
[tex]f(\frac{2}{9})=1[/tex]
Step-by-step explanation:
we have
[tex]f(x)=3x+\frac{1}{3}[/tex]
we know that
f(2/9) is the value of the function f(x) when the value of x is equal to 2/9
so
For x=2/9
substitute the value of x in the function and solve for f(x)
[tex]f(x)=3(\frac{2}{9})+\frac{1}{3}[/tex]
[tex]f(x)=\frac{2}{3}+\frac{1}{3}[/tex]
[tex]f(x)=\frac{3}{3}[/tex]
[tex]f(x)=1[/tex]
therefore

What is the y-intercept of the line given by the equation below? Enter your answer as an ordered pair.
y = 2x + 10
Final answer:
The y-intercept of the equation y = 2x + 10 is 10, which means the ordered pair for the y-intercept is (0, 10).
Explanation:
The y-intercept of the line given by the equation y = 2x + 10 can be found by looking at the equation in its slope-intercept form, which is y = mx + b. Here m represents the slope of the line, and b represents the y-intercept. Since the y-intercept is the value of y when x is zero, we can determine that the y-intercept for this line is the constant term in the equation, 10. Therefore, the y-intercept as an ordered pair is (0, 10).

a wooden dowel has a diameter of 1.20 cm it floats in water with 0.400 cm its diameter above water determine the density of the dowel?
Final answer:
The density of the wooden dowel can be determined using the principle of buoyancy to calculate the volume of the submerged part and the total volume of the dowel which, when combined with the mass of the displaced water, provides the density of the dowel.
Explanation:
To determine the density of the wooden dowel based on its flotation characteristics, you can use the principle of buoyancy, which states that the buoyant force exerted on a submerged object equals the weight of the fluid displaced by that object. Since the dowel floats in water, the weight of the displaced water equals the weight of the dowel.
First, calculate the volume of the submerged part of the dowel: The dowel has a diameter of 1.20 cm, and the submerged height is the total diameter minus the portion above water, which is 1.20 cm - 0.400 cm = 0.800 cm. The volume (V) of the submerged cylinder is V = πr^2h, where r is the radius (half the diameter) and h is the submerged height. Plugging in values, V = π(0.6 cm)^2(0.8 cm).
Second, calculate the mass (m) of the dowel using the density (ρ) of water (1 g/cm^3) and the volume of water displaced which equals the volume of the submerged part of the dowel: m = ρ_water * V_submerged.
Finally, to find the density of the dowel, divide the mass of the dowel by the total volume of the dowel. The total volume is the same formula V = πr^2h, but with h being the full diameter of the dowel since it's cylindrical. The density of the dowel is ρ_dowel = m / V_total.
Using these steps, you can calculate the density of the dowel.

Answer:
Second option: On a coordinate plane, rectangle A'B'C'D' prime has points [tex](-4,4),(12,4),(12,-4),(-4,-4)[/tex]
(See the graph attached)
Step-by-step explanation:
For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.
In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image) are the following:
[tex]A(-1,1)\\\\B(3,1)\\\\C(3,-1)\\\\D(-1,-1)[/tex]
Therefore, to find the vertices of the rectangle A'B'C'D' (The Image) that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:
[tex]A'=((-1)(4),(1)(4))=(-4,4)\\\\B'=((3)(4),(1)(4))=(12,4)\\\\C'=((3)(4),(-1)(4))=(12,-4)\\\\D'=((-1)(4),(-1)(4))=(-4,-4)[/tex]
Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.

The circumference of a circle is 314 units. What is the area?
Answer:
7850 square units
Step-by-step explanation:
According to the question;
Circumference of a circle is 314 units;We are required to find the area of the circle;
First, we need to ask ourselves how we get the perimeter of a circle;Perimeter of a circle = pi × D or 2 pi r
Therefore;
Rearranging the formula;
D = Perimeter ÷ pi
Taking pi to be 3.14
Then;
Diameter = 314 units ÷ 3.14
= 100 units
But, radius = Diameter ÷ 2
= 100 units ÷ 2
= 50 units
We also need to know how we calculate the area of a circle;
Area of a circle = pi×r²
Therefore;
Taking pi as 3.14
Then, Area = 3.14 × 50²
= 7850 square units
Thus, the area of the circle is 7850 square units

Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form.
Passing through (4,-6) and perpendicular to the line whose equation is y=1/4x+4
Write an equation for the line in point-slope form.
The line passing through the point (4, -6) and perpendicular to the line y=1/4x+4 has an equation in point-slope form of y + 6 = -4(x - 4) and in slope-intercept form, it is y = -4x + 10.
Explanation:In Mathematics, lines that are perpendicular have slopes that are negative reciprocals of each other. This means if one line has a slope of m, the line perpendicular to it will have a slope of -1/m. The given line has a slope of 1/4, so the line perpendicular to it will have a slope of -4 (negative reciprocal of 1/4).
The point-slope form of a line is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Thus, the equation of a line passing through the point (4, -6) with a slope of -4 can be expressed as y - (-6) = -4(x - 4), which simplifies to y + 6 = -4x + 16 or y = -4x + 10.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Therefore, based on our previous findings, the equation of the line in slope-intercept form is y = -4x + 10.
