How many solutions are there to the equation below? -46 = 3x + 7x
if p is the midpoint of xy, xp=8x-2 and py=12x-30, find the value of x
To find the value of x, we can use the midpoint formula which is 16/9.
Explanation:To find the value of x, we can use the midpoint formula. According to the formula, the x-coordinate of the midpoint is the average of the x-coordinates of the two endpoints, and the same applies to the y-coordinate.
Given that XP = 8x - 2 and PY = 12x - 30, we can set up the equation:
(8x - 2 + 12x - 30) / 2 = x
Simplifying the equation, we get:
(20x - 32) / 2 = x
Multiplying both sides of the equation by 2 to eliminate the fraction, we get:
20x - 32 = 2x
20x - 2x = 32
18x = 32
x = 32/18
x = 16/9

Answer:
[tex]p^2\sqrt[4]{27pq^3}[/tex]
Step-by-step explanation:
[tex](3p^3q)^\frac{3}{4}[/tex]
To get radical form , remove the fractional exponent
[tex](a^m)^n=a^{mn}[/tex]
multiply the exponent 3/4 inside the parenthesis
[tex]3^\frac{3}{4} p^{3 \cdot \frac{3}{4}} q^\frac{3}{4}[/tex]

[tex]\sqrt[4]{27} \cdot p^2\sqrt[4]{p} \cdot \sqrt[4]{q^3}[/tex]
[tex]p^2\sqrt[4]{27pq^3}[/tex]
The radical form of the expression [tex]\rm \left (3p \times 3q \right )^{\frac{3}{4}}[/tex] will be [tex]\left ( 3\sqrt{3} \right ) \left (\sqrt[4]{p^3q^3} \right )[/tex].
How do convert the exponent into the simplest radical form?If the power of the variable "a" is b/c. Then the simplest radical form of the expression will be
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
[tex]\rm \left ( a \right )^{\rm \frac{b}{c}} = \rm \sqrt[\rm c]{\rm a^b}[/tex]
The expression is given below.
[tex]\rm \rightarrow \left (3p \times 3q \right )^{\frac{3}{4}}[/tex]
We know that (ab)ⁿ = aⁿ × bⁿ. Then the expression will be
[tex]\rm \rightarrow \left (3^{\frac{3}{4}} \times p^{\frac{3}{4}} \times 3^{\frac{3}{4}} \times q^{\frac{3}{4}} \right )[/tex]

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 2 cos 5θ
Answer:
The graph is symmetric about the x-axis.
Step-by-step explanation:
1. Symmetry about the x-axis: If the point (r, θ ) lies on the graph, then the point (r, -θ ) or (-r, π - θ ) also lies on the graph.
2. Symmetry about the y-axis: If the point (r, θ ) lies on the graph, then the point (r, π - θ ) or (-r, -θ ) also lies on the graph.
3. Symmetry about the origin: If the point (r, θ ) lies on the graph, then the point (-r, θ ) or (r, π + θ ) also lies on the graph.
The given polar equation is
[tex]r=2\cos (5\theta)[/tex]
Check the equation by (r, -θ).
[tex]r=2\cos (-5\theta)=2\cos (5\theta)=r[/tex]
Therefore, the graph is symmetric about the x-axis.
Check the equation by (-r, -θ).
[tex]-r=2\cos (-5\theta)=2\cos (5\theta)=r\neq -r[/tex]
Therefore, the graph is not symmetric about the y-axis.
Check the equation by (-r, θ).
[tex]-r=2\cos (5\theta)=2\cos (5\theta)=r\neq -r[/tex]
Therefore, the graph is not symmetric about the origin.

Point H is the circumcenter of triangle DEF.
Which must be true? Check all that apply.
Point H is the center of the circle that passes through points D, E, and F.
Point H is the center of the circle that passes through points L, M, and N.
HE=HD
LH=NH
MEH NEH
DLH FNH
Answer:
the correct answers are:
a. ) Point H is the center of the circle that passes through points D, E, and F.
c. ) HE=HD
Point H, being the circumcenter, ensures it is the center of the circle through D, E, and F and that HE equals HD; other statements regarding unrelated points cannot be confirmed.
Explanation:If Point H is the circumcenter of triangle DEF, then the following must be true:
Point H is the center of the circle that passes through points D, E, and F since the circumcenter is equidistant to all vertices of the triangle, forming the circumscribed circle.HE=HD since, by the definition of a circumcenter, it is equidistant from all vertices of the triangle.The other statements regarding points L, M, N cannot be determined to be true without additional information, as they are not related to triangle DEF and its circumcenter directly.
In summary, Point H as the circumcenter ensures it is at the center of the circumscribable circle through D, E, and F, and that HE equals HD.

The given equation of the line is in slope-intercept form. To convert it to standard form, simply rearrange so that all terms are on one side of the equation resulting in 3x + y = 2.
Explanation:The equation you're given is y=2-3x which is in the slope-intercept form i.e., y = mx + b, where m is the slope and b is the y-intercept. To convert this equation to a standard form, the general approach is to eliminate fractions and have the 'y' and 'x' terms on the same side of the equation.
Starting from y = 2 - 3x, add 3x to both sides of the equation to get it in the standard form. So, it becomes 3x + y = 2, which is the standard form of the given equation.

For dinner, Abelita chooses the Italian salad that costs $3.99 before tax, and Franco chooses the fettuccini alfredo that costs $7.17 before tax. If the sales tax is 5 percent, explain how to find the total cost for their dinner.
Answer: The total cost of the dinner is found by adding the two prices together. Then this sum is multiplied by 1.05, which is 100% + 5%, to get a cost of $11.72.
Step-by-step explanation:
This is the sample answer.
To calculate the total cost including sales tax, convert the percent tax rate to a decimal, multiply it by the meal's cost, and add it to the original cost. In this case, a 5 percent tax on a $3.99 salad and a $7.17 fettuccini alfredo results in a final total cost of $11.72.
Explanation:Calculating Total Cost with Sales TaxFirst, to find the sales tax for Abelita's Italian salad and Franco's fettuccini alfredo, you convert the tax rate from a percent to a decimal. The tax rate is 5 percent, which as a decimal is 0.05. Next, add the cost of the Italian salad ($3.99) and fettuccini alfredo ($7.17) to get the total cost before tax, which is $11.16. Multiply this total by the tax rate to find the amount of sales tax: $11.16 × 0.05 = $0.558. Round this to the nearest cent, which gives us $0.56.
The next step is to add the sales tax to the total cost before tax to find the final total cost. Thus, $11.16 (meal cost) + $0.56 (sales tax) = $11.72. Therefore, the total cost for their dinner, including the 5 percent sales tax, is $11.72.

A table is on sale for $403, which is 38% less than the regular price. what is the regular price
The regular price of the table is $650.
The student has asked to find the regular price of a table that is currently on sale for $403, which is 38% less than the regular price. To find the regular price, we can consider the sale price to be 62% (100% - 38%) of the regular price. Let's denote the regular price as R. Thus, we can set up the equation 0.62 * R = $403. Solving for R, we divide both sides by 0.62 to find the regular price:
R = $403 / 0.62
R = $650
Therefore, to find the regular price of a table on sale for $403 at 38% off, we determine that the sale price is 62% of the regular price. By dividing the sale price by 0.62, we discover that the regular price is $650.
