Answer: y = 11-x
This is the same as y = -x+11
To get either result, we subtract x from both sides of the original equation. This is to undo the plus x.
A(n) ____ of a polyhedron is the intersection of the _____ of the polyhedron
An Edge of a polyhedron is the intersection of the Vertex of the polyhedron.
What is a polyhedron?A polyhedron can be described as the 3-dimensional solid that is been formed through the combination of more than one polygons and they usually have different faces which is been used in knowing them as well as their classification.
It should be noted that this polyhedrons can be categorized based on the number of faces that can be found on them, however in this case we can conclude that the Vertex serves as the point of intersection that the edges of polyhedron has.

The evaluations of the quadratic equation at the values of 0, 7 and - 5 are 5, 1356 and - 460, respectively.
How to evaluate a polynomial function
In this question we have the definition of a quadratic equation, which has to be evaluated at three distinct values of x. Evaluating a function consists in substituting the independent variable by a value and simplify the expression. Now we proceed to evaluate the function:
f(0) = 4 · 0³ - 7 · 0 + 5
f(0) = 5
f(7) = 4 · 7³ - 7 · 3 + 5
f(7) = 1372 - 21 + 5
f(7) = 1356
f(- 5) = 4 · (- 5)³ - 7 · (- 5) + 5

ginny wants to join a local dance club that has dance events every.there are two memberships options avaiable
Using linear functions, it is found that Ginny must attend at least 13 events to make the premier member package cost less.
What is the complete question?The complete question is given as follows:
"Ginny wants to join a local dance club that has dance events every week. There are two membership options available: Ginny may become a premier member by paying a fee of $150 per year and attend an unlimited number of dances. Ginny may become a regular member by paying a fee of $50 and then pay $8 per dance she attends. How many dances must Ginny attend such that becoming a premier member will cost less than becoming a regular member? "
What is a linear function?A linear function is modeled in slope-intercept form by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The flat fee is the intercept.The cost per dance is the slope.Hence the functions for each option are given as follows:
P(x) = 150.R(x) = 50 + 8x.Being a premier member will cost less when:
P(x) < R(x).
Hence:
150 < 50 + 8x
8x > 100
x > 100/8
x > 12.5 -> at least 13 events.
Ginny must attend at least 13 events to make the premier member package cost less.

solve system of equations by using elimination method. (solve for (x,y,z) please explain the steps im so confused.
4x-y-2z=-8
-2x+4z=-4
x+2y=6
The solutions of the system of equations are:
x = -2, y = 4, z = -2
How to solve a system of equations by the elimination method?
Here we have the system of equations:
4x - y - 2z = -8
-2x + 4z = -4
x + 2y = 6
To eliminate one variable, we can add the second equation and two times the third equation, we will get:
(-2x + 4z) + 2*(x + 2y) = -4 + 2*6
Now we can simplify that so we get:
4z + 4y = -4 + 12
4*(z + y) = 8
z + y = 8/4 =2
z + y = 2
With that we can write z in terms of y.
z = 2 - y
And with the third equation we can write x in terms of y.
x = 6 - 2y
Replacing that in the first equation we get:
4*(6 - 2y) - y - 2*(2 - y) = -8
Now we can solve this for y.
24 - 8y - y +2y - 4 = -8
20 - 11y = -8
-7y = -28
y = 28/7 = 4
Now that we know the value of y we can find the values of x and z.
x = 6 - 2y = 6 - 2*4 = -2
z = 2 - y = 2 - 4 = -2
The solutions of the system of equations are:
x = -2, y = 4, z = -2

The Thai Pepper has a hotness rating of 7.5 x 10^4 on the Scoville scale.
The Red Savina Habanero has a hotness rating of 4.6 x 10^5 on the Scoville scale.
How many times hotter is the Red Savina Habanero than the Thai Pepper?
a
Divide (4.6 x 10^5) / (7.5 x 10^4) = (4.6 / 7.5) x (10^(5-4)) = .613 x 10^1 = 6.13 times hotter
b
Multiply (7.5 x 10^4) x (4.6 x 10^5) = (7.5 x 4.6) x (10^(4+5)) = 34.5 x 10^ 9 = 3.45 x 10^10
c
Divide (7.5 x 10^4) / (4.6 x 10^5) = (7.5 / 4.6) x (10^(4-5)) = 1.63 x 10^ 1 = 16.3 times hotter
d
Multiply (7.5 x 10^4) x (4.6 x 10^5) = (7.5 x 4.6) x (10^(4+5)) = 34.5 x 10^ 9 = 3.45 x 10^10 times hotter
The Red Savina Habanero is 6. 13 times hotter than the Thai Pepper. Option A
What is ratio?A ratio can be defined as the comparison of two or more numbers on the basis of their sizes in relation to each other;
Given that;
Thai Pepper has a hotness rating of 7.5 x 10^4 Red Savina Habanero has a hotness rating of 4.6 x 10^5To determine the ratio, we have to divide Red Savina Habanero hotness rating by Thai Pepper hotness rating
This is represented as;
= 4.6 x 10^5 / 7.5 x 10^4
= 6. 13 times
The Red Savina Habanero is 6. 13 times hotter

By taking the quotient between the ratings, we can see that Red Savina Habanero is 6.13 times hotter than the Thai Pepper.
How many times hotter is the Red Savina Habanero than the Thai Pepper?We know that the Thai Pepper has a hotness rating of 7.5*10⁴, while the Red Savina Habanero has a hotness rating of 4.6*10⁵.
We want to see how many times hotter is the Red Savina Habanero than the Thai Pepper, to find that we need to take the quotient between the rating for the Habanero and the rating for the Pepper.
It gives:
Q = (4.6*10⁵)/(7.5*10⁴)
This can be rewritten as:
Q = (4.6/7.5)*(10⁵/10⁴)
=0.613*(10 ⁵⁻⁴) = 0.613*10
Now, we want to write this in scientific notation, so we need to have a single digit different than zero in the left side of the decimal point.
Then we can rewrite:
0.613*10 = 6.13*10⁰ = 6.13
We conclude that the Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

the domain of f(x) is the range of its inverse, or namely the domain of f(x) is the same set as the range of f⁻¹(x), so for any (a , b) pair on the domain of f(x), there's a (b , a) on the range of f⁻¹(x).

Suppose that two balls are selected with replacement from a bag that contains 10 white and 5 black balls. What is the probability that both balls are black?
The probability that both the balls are black is [tex]\frac{1}{9} \\[/tex] .
Probability is the section of mathematics which deals with the likelihood of an event happening.
The value of probability is a fraction which always lies between 0 and 1. it is defined as the ratio of the favorable outcomes of an event to the total outcome of an event.
Given the bag has 10 white balls and 5 black balls. Therefore the total number of balls in the bag is 15 .
Hence the sample space is 15 .
The balls are drawn with replacement. Therefore for the first ball pick:
Number of favorable outcomes = 5
Total number of outcomes = 15
Probability = favorable outcome ÷ total outcome
Therefore [tex]P_1=\frac{5}{15}=\frac{1}{3}[/tex]
Now the ball is placed back and the second ball is picked.
Number of favorable outcomes = 5
Total number of outcomes = 15
Probability = favorable outcome ÷ total outcome
Therefore [tex]P_2=\frac{5}{15}=\frac{1}{3}[/tex]
Now the total probability that both the balls are black is :
P = P₁×P₂
[tex]P=\frac{1}{3}\times \frac{1}{3}\\\\P=\frac{1}{9}[/tex]
Hence the probability of picking two black balls is [tex]\frac{1}{9} \\[/tex] .
