Answer:
-x² + x - 1
Step-by-step explanation:
(f/g)(x) means that you have to divide f(x) by g(x).
\(\frac{x^4-x^3+x^2}{-x^2}\\ -x^2+x-1\)
When dividing exponents with the same base, you have to subtract the exponents to find the quotient.
When dividing with negatives, you have to switch the sign of the other number.
Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
14/100+(-0.45) / 0.2
is it -2.11 or -2.39?
If possible, can you show the work of the answer you got?

What does the next consecutive odd number after
another odd number mean? Thanks
Answer:
I'm pretty sure its just the next number. So the equation would be n + (n +2) + (n + 4), and for example they might be talking about n. And they want to know the next consecutive odd number, the next one would be (n + 2).
Hope that helps.

Answer:
Consecutive Numbers are numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

$3.00 marked up 72%
(please show your work!!)
thank you❤️❤️
==================================================
Work Shown:
72% = 72/100 = 0.72
72% of $3.00 = 0.72*3.00 = 2.16
The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars
-------
We can find this answer through this alternative route:
1.72*3 = 5.16
The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
Answer:
marked up $2.16
total: $5.16
Step-by-step explanation:
3 dollars is 100 percent
30 cents is 10 percent
3 cents is 1 percent
So you will do 10 percent 7 times and 1 percent 2 times
30 cents times 7 is $2.10 + %0.06 so it is marked up $2.16
Total: $5.16
would be much appreciated
Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
The graph of a function is shown below. Which inequality represents the domain of the function?
Answer is:
D.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Answer:
4 inches wide
Step-by-step explanation:
We see that 984 ÷ 328 = 3, so the real Eiffel Tower is 3 times as tall as it is wide. So the scale model must also be 3 times as tall as it is wide. If the scale model is 12 inches tall, then it is 12 ÷ 3 = 4 inches wide.

84 because PEMDAS(parenthesis/Exponents/Multiply/Divide/Add/Subtact) says you do parenthesis first. So you add 9 and 3 to get 12. The you do 12*7 to get 84.

Solve the equation t − 3 = 17 for t.
−20
20
−14
14
The value of t = 20
This is the given Equation:
t - 3 = 17
Now we have to take (-3) from the left to right side to determine the value of t.
It will change the sign of 3.
t = 17 + 3
t = 20
So, the value of 't' in the given Equation is 20.

Which equation could be solved using this application of the quadratic formula?
A. -2x2 − 8 = 10x − 3
B. 3x2 − 8x − 10 = 4
C. 3x2 + 8x − 10 = -8
D. -2x2 + 8x − 3 = 4
Answer:
3x^2 +8x -10=-8
Step-by-step explanation:
A quadratic equation is
ax^2 + bx +c=0
has a formula
-b ± sqrt( b^2 -4ac)
--------------------------
2a
We know a = 3 b = 8 and c = -2
3x^2 +8x -2=0
Subtract 8 from each side
3x^2 +8x -2 -8=0-8
3x^2 +8x -10=-8
That is choice C
Answer:
C.
Step-by-step explanation:
Consider equation C:
3x^2 + 8x - 10 = -8
3x^2 + 8x - 2 = 0
Here a = 3, b = 8 and c = -2
Applying the quadratic formula:
x = [-b +/- √(b^2 - 4ac)] / 2a
x = [-8 +/- √(4(3)(-2)] / 2(3)
- which is the one in the question.
So it is equation C.
A math team is working through a set of puzzles. The following diagram describes the numbers of puzzles they've started and not yet started.
Answer:2:5
Step-by-step explanation: We can count the equal parts in the diagram to find the ratio of puzzles started to total puzzles, but that ratio is not one of the choices.
To make an equivalent ratio, we multiply both values in the first ratio by the same number. We can also divide both values by the same number.
Identifying the given ratio
6 + 9 = 15
There are 6 puzzles started for every 15 total puzzles.
The answer choices use smaller numbers. Let's create an equivalent ratio by dividing 6 and 15 by the same number.
Creating an equivalent ratio
We can divide 6 and 15 by 3 to get 2 and 5
Yes, the ratio 2:5 is equivalent to 6:15!
The ratio of puzzles started to total puzzles answers is 2:5.

The reflection of point S across the y-axis is point ___. The reflection of point Q across the x-axis and the y-axis is point ____, whose coordinates are ( __ , __ ).
Answer:
The reflection of point S across the y-axis is point V . The reflection of point Q across the x-axis and the y-axis is point V , whose coordinates are ( -5 , -5.5 ).
===============================================
Explanation:
Point S is exactly 5 units away from the vertical y axis. Move from point S(5,-5.5) to the location (0,-5.5); ie move 5 units to the left. Then move another 5 units to the left to land on point V(5, -5.5)
Points V and S are the same distance away from the mirror line.
-----------------------
Reflecting point Q over the x axis lands us on point S. This time we move down 5.5 units to get to the x axis. Then move another 5.5 units to arrive at point S. As discussed above, point S then will reflect over the y axis to get to point V.
Side note: Combining two reflections produces a rotation. So effectively, going from Q to V is a rotation of 180 degrees.
