The value of 9 x^2 + 4 x – 11 is ______ when x = 3 . 2 and ______ when x = − 2 .
The value of 9 x^2 + 4 x – 11 is 93. 96 when x = 3.2 and 17 when x = -2
What are algebraic expressions?Algebraic expressions are expressions composed of variables, terms, factors, constants and coefficients.
They are also made up of mathematical or arithmetic operations
Given the expression;
9 x^2 + 4 x – 11
Substitute the value of x as 3. 2
9(3.2 )² + 4(3.2) - 11
expand the bracket
9(10. 24) + 12. 8 - 11
104. 96 -11
93. 96
Substitute the value of x as -2
9(-2)² + 4(-2) - 11
9(4) - 8 - 11
17
Thus, the value of 9 x^2 + 4 x – 11 is 93. 96 when x = 3.2 and 17 when x = -2

-7x-1(10-x)=-58
Using the the distributive property equation
______________________________
1.) To find the opposite of 10−x, find the opposite of each term:[tex]10[/tex] × [tex]-1=-10[/tex][tex]-x[/tex] × [tex]-1=-x[/tex]- This is another way of saying multiply each side by -1.
2.) Find the opposite of −x:[tex]-x=x[/tex]
- Since we have 2 negatives next to each other, one must be turned into a positive, in this case it's the x.
3.) Combine −7x and x:[tex]-7x+x=-6x[/tex]
- Combine them because you can only have one variable (x) in the end.
4.) Add 10 to both sides:[tex]-10+10=[/tex][tex]-58+10=-48[/tex]
- We do this to get rid of not only the 10 but the other numbers as well, and the only way to do so it to cancel them out.
5.) Divide both sides by −6:[tex]-6x[/tex] ÷ [tex]-6=x[/tex][tex]-48[/tex] ÷ [tex]-6=8[/tex]- We do this to get x alone with one number left over, and the only way to do so is to cancel everything out by dividing.

YM is a median of the triangle below. XM = 2x + 2 and ZM = 4x - 8. What 5 points
is the length of XM?
12
16
-2
10
Answer:
Option A: 12
Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12

Step-by-step explanation:
Step 1: Define Equation
6(x - 1) = -72
Step 2: Solve for x
Divide 6 on both sides: x - 1 = -12Add 1 to both sides: x = -11Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(-11 - 1) = -72Subtract: 6(-12) = -72Multiply: -72 = -72Here we see that -72 does indeed equal -72.
∴ x = -11 is a solution to the equation.
Answer:
x = - 11
Step-by-step explanation:
Given
6(x - 1) = - 72 ← divide both sides by 6
x - 1 = - 12 ( add 1 to both sides )
x = - 11

Rita earns $18.00 per hour. If she gets a 4% raise, what will be her new hourly wage?
Answer:
Step-by-step explanation:
Probably $20 just by estimating
Answer:
Rita's new hourly wage will be $18.72.
Step-by-step explanation:
To solve this problem, we first need to calculate 4% of $18.00 to find the raise.
18 x 0.04 = 0.72
Now, we need to add this to the original hourly wage of $18.
18 + 0.72 = $18.72
Therefore, Rita's new hourly wage will be $18.72.

is your birth order related to your choice of college majors? a statistics professor at a large university polled his students to find out what their majors were
The birth order is related to the choice of major. The statistics professor at the university polled his students in finding out the majors and position based on family birth order.
What is statistics?Statistics, a branch of applied mathematics, is concerned with the collection of, description of, analysis of, and inferences from quantitative data. Major contributions to the mathematical theories underlying statistics come from probability theory, linear algebra, and differential and integral calculus.
Finding valid inferences about big groups and general events from the behavior and other observable characteristics of small samples is a major challenge for statisticians, or persons who study statistics. These small samples are representative of a small subset of a larger group or a small number of isolated occurrences of a widespread phenomena.
Almost all scientific fields, including the physical and social sciences, as well as business, the humanities, government, and manufacturing, use statistics. Fundamentally, statistics is an area of applied mathematics that resulted from the application of calculus and linear algebra, among other mathematical techniques, to probability theory.

I hope l have answered your question. ❤❤❤If the total price for two cars at a dealership is $91,000, where one car's price is
$11,000 less than twice the other, what is the price of the cheaper vehicle?
The price of the cheaper vehicle is $34000. And the price of the other vehicle is $ 57000. The total becomes $91000.
The total price for two cars at a dealership is $91,000, where one car's price is $11,000 less than twice the other.
There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.
Let the price of one car be 'X' and other be 'Y' such that:
X+Y = $91000.
According to the question,
X = 2Y - $11000
Manipulating and calculating both the equations we get,
X = $57000 and Y = $34000.
So the cheaper car is of $34000.

Answer: r = 2
Step-by-step explanation: The general equation is:
(x-a)² + (y-b)² = r²
where (a,b) = coordinates of the center, and r = radius
x² + y² = 4 is the same as
(x-0)² + (y-0)² = 2²
So, the center is at (0,0) and the radius is 2.

An airplane is flying from New York City to Los Angeles. The distance it travels in miles d, is related to the time in seconds, t, by the equation d=0.15t. Do NOT include units with your answer.A. How fast is it flying in miles per second?B. How far will it travel in 30 seconds?C. How long will it take to go 12.75 miles?
Answer:
A. 0.15
B. 0.45
C. 85
Step-by-step explanation:
Given that:
Equation to represent the relation between distance, [tex]d[/tex] in miles and time [tex]t[/tex] in seconds:
[tex]d=0.15t[/tex]
A.
To find: The speed of airplane in miles per second.
Formula for speed is given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Here, we will have to find the value of [tex]\frac{d}{t}[/tex].
Dividing the given equation by [tex]t[/tex], we get:
[tex]\dfrac{d}{t}=0.15[/tex]
[tex]d[/tex] is in miles and [tex]t[/tex] is in seconds.
Therefore, the answer is 0.15.
B.
Distance traveled in 30 seconds.
Given that: [tex]t[/tex] = 30 seconds
To find: [tex]d = ?[/tex] in miles
[tex]d = 0.15\times 3 = 0.45[/tex]
C.
The time taken to travel a distance of 12.75 miles.
Given that : [tex]d =12.75\ miles[/tex]
To find: [tex]t = ?[/tex] seconds
[tex]12.75 = 0.15t\\\Rightarrow t = \dfrac{12.75}{0.15}\\\Rightarrow \bold{t = 85}[/tex]

The product of two consecutive integers is 72.
Which of the following could be their sum?
E. -17
F. -1
G. 1
H. 18
Answer:
First I would find the square root of 72 with a calculator, which happens to be 8.49 (rounded to the nearest hundreth)
So we know that the two integers will be close to 8.48
Since they are consecutive, lets first test out 8 and 9
We multiply these two and get 72, which is the number we were looking for.
now we find their sum.
9 + 8 = 17
Now since this is not part of the answers, we now asume that both 9 and 8 are negative numbers, since negative times a negative is a positive, but a negative plus a negative can still be negative.
-9 + -8 = -9 - 8 = -17!
So, the answer you are looking for is E: -17
