Answer:
1
Step-by-step explanation:
since the 2 functions equal each other:
-2x + 3 = 4x - 9
add -2x to both sides
3 = 6x - 9
add 9 to both sides
12 = 6x
divide by 6
2 = x
you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway
-2(2) + 3
-4 + 3
-1 = y
Now we'll find x + y, input them and it's 2 + (-1), which is 1

Answers
The coordinates of the circumcenter of the triangle are (5.5, -5.5).
The vertices of the triangle are A(3, -6), B(5, -3), and C(8, -6).The circumcenter is the point at which the perpendicular bisectors of a triangle's sides connect and are equidistant from its three vertices.The midpoint of AB is ((3+5)/2, [-6+(-3)]/2) = (4, -4.5).The midpoint of BC is ((5+8)/2, [-3+(-6)]/2) = (6.5, -4.5).The slope of AB is (-3-(-6))/(5-3) = 3/2.The slope of the perpendicular bisector of AB is -1/(3/2) = -2/3.The equation of the perpendicular bisector of AB is :(y - (-4.5)) = (-2/3)(x - 4)y + 4.5 = (-2/3)(x - 4)3(y + 4.5) = (-2)(x - 4)3y + 13.5 = -2x + 83y = -2x - 5.5The slope of BC is (-6-(-3))/(8-5) = -3/3 = -1The slope of the perpendicular bisector of BC is -1/(-1) = 1The equation of the perpendicular bisector of BC is :(y - (-4.5)) = (1)(x - 6.5)y + 4.5 = x - 6.5y = x - 11We solve for the point of intersection of the perpendicular bisectors and get (5.5, -5.5).To learn more about circumcenter, visit :

If neither a nor b are equal to zero, which answer most accurately describes the product of (a + b)(a - b)?
The product of a complex conjugate is always an imaginary number.
The product of a complex conjugate is always zero.
The product of a complex conjugate is always a mix of real and imaginary numbers.
The product of a complex conjugate is always a real number.
Answers
The statement is correct. The product of a complex conjugate is always a real number.
Given, if neither a nor b are equal to zero then we have to conclude that which of the following statement accurately describes the product of (a + ib)(a - ib). So, let's proceed to solve the question accordingly.
Now, solve the product of (a + ib)(a - ib), we get
(a + ib)(a - ib) = a(a - ib)+ib(a - ib)
= a^2-iab+iab+(ib)^2
= a^2+i^2b^2
we know that, i^2 = -1, then
= a^2+i^2b^2 = a^2+b^2
⇒(a + ib)(a - ib) = a^2+b^2
∴ a^2+b^2 will always give a real number.
Therefore, option (d) is correct. The product of a complex conjugate is always a real number.

Answers
Answer:
−6x − 15y − 14q − 21p
Step-by-step explanation:
Let's simplify step-by-step.
−3(2x+5y)−7(2q+3p)
Distribute:
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Answer:
=−21p−14q−6x−15y
The equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
−3(2x + 5y) − 7(2q + 3p)
For solving the equation we have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
First, open the bracket and multiply,
=−3(2x + 5y) − 7(2q + 3p)
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Rearrange the equation as
=−21p−14q−6x−15y
Thus, the equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.

in a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 58 and a standard deviation of 10. using the empirical rule (as presented in the book), what is the approximate percentage of daily phone calls numbering between 28 and 88? do not enter the percent symbol.
Answers
The percentage of daily phone calls numbering 28 and 88 = 99.7%
The given Standard Deviation is 10, and the mean is 58
Using the formula
z = (X -Mean) / Standard Deviation
z value corresponding to X = 28 is
z = (28 - 58)/ 10
z = -30/10
z = -3
z value corresponding to X = 88
z = (88 - 58) / 10
z = 3
According to the empirical rule
"Empirical Rule" is also called as the three sigma rule
We have to know
One Standard Deviation of the mean , covers 68% of data
Two Standard Deviation of the mean , covers 95% of data
Three Standard Deviation of the mean , covers 99.7% of data
Therefore, +/- to the third Standard Deviation covers of the items 99.7% of data.
Therefore, the percentage of daily phone calls numbering 28 and 88 = 99.7%

The number of marbles in the bag is illustrated using proportions.

The given parameters are:
[tex]\mathbf{B : S = 3 : 1}[/tex]

[tex]\mathbf{n = 40}[/tex]
First, we combine the ratios
[tex]\mathbf{B:S:D = 3:1:4}[/tex]
The number of basketballs is calculated as follows:
[tex]\mathbf{Basketball= \frac{B}{B + S + D} \times n}}[/tex]
So, we have:
[tex]\mathbf{Basketball= \frac{3}{3 + 1 + 4} \times 40}[/tex]
[tex]\mathbf{Basketball= \frac{3}{8} \times 40}[/tex]

What is a frequency distribution?
In statistics, a frequency distribution is a graph or data set that shows the frequency of occurrence of each possible outcome of a repeatable event observed many times. Election results and test scores listed by percentile are simple examples. A frequency distribution can be represented graphically as a histogram or a pie chart. The number of observations for each class is shown in a frequency distribution (class is a value or a range of values).What is a relative frequency distribution?
A relative frequency distribution, which is related to a probability distribution and is widely used in statistics, shows the proportion of the total number of observations associated with each value or class of values. The relative frequency distribution demonstrates how close the values are to one another.Therefore, the statement "a frequency distribution shows the number of observations for each class (class is a value or a range of values), and a relative frequency distribution shows how close the values are to each other" is TRUE.
