Answer:
Reflect the graph f(x) across the x axis to obtain the graph g(x).

Step-by-step explanation:
following the accepted steps you would first reflect the graph across the y axis due to the negative sign within the function, then you would reflect the result across the x axis due to the negative sign outside of the function.
In practice however you only need to reflect across the x axis as -(-x)^2 simplifies to -x^2

80% of ____games is 32 games
Answer:
If its multiplying then 40 if adding then 31.2
Step-by-step explanation:
Put 80 over 100
simplify to get 4/5x = 32
Multiply both sides by 5/4 (because you flip)
the fives cancel out and the fours
then you have x=5/4 x 32
four goes into 32 making it x=5 x 8
5x8=40
:)
Answer:
The answer is 40.
Step-by-step explanation:
80% + 20% = 100%
80% ÷ 20% = 4
32 ÷ 4 = 8
32 + 8 = 40
100% = 40

name the property that is shown by the following expression (9x3)x4=9x(3x4)
the associative property is used.
Which property is used in the expression?
The Associative property of multiplication says that (a × b) × c = a × (b × c),
so we can perform the multiplication in any order we want.
If you look at the expression:
(9x3)x4=9x(3x4)
The difference is that first we start with the product 9×3, and in the right side the first product we need to solve is 3×4, so the associative property is used.
Solve for "X".

A carpenter goes through 2 2 ⁄6 boxes of nails finishing 3 1 ⁄4 rooves. How much would he use finishing 2 rooves?
Answer:
1 17/39 boxes.
Step-by-step explanation:
3 1/4 rooves requires 2 2/6 boxes
So 2 rooves require 2 * 2 2/6 / 3 1/4 boxes.
= 2 * 14/6 / 13/4
= 28/6 * 4/13
= 56/39
= 1 17/39 boxes.
The question involves calculation of usage rate per roof by dividing the total boxes used by the number of rooves completed and then applying that rate to determine number of boxes needed for 2 rooves.
Explanation:The question asks how many boxes of nails a carpenter would use for 2 rooves if he goes through 2 2/6 boxes to complete 3 1/4 rooves. To find out the number of boxes needed for 2 rooves, we need to calculate the rate of nail box usage per roof and then apply that rate to 2 rooves.
First, we simplify 2 2/6 to a mixed number: 2 1/3.
Then we divide the number of boxes by the number of rooves to get the usage rate per roof:
2 1/3 boxes ÷ 3 1/4 rooves = usage rate per roof.
Once we get the usage rate, we multiply it by 2 to find the boxes needed for 2 rooves.
This process involves converting mixed numbers to improper fractions, performing division, and then multiplication.

Derive the equation of the parabola with a focus at (−2, 4) and a directrix of y = 6. Put the equation in standard form.
f(x) = one fourthx2 − x + 4
f(x) = −one fourthx2 − x + 4
f(x) = one fourthx2 − x + 5
f(x) = −one fourthx2 − x + 5
Answer:
B
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
[tex]\sqrt{(x+2)^2+(y-4)^2}[/tex] = | y - 6 |
Squaring both sides
(x + 2)² + (y - 4)² = (y - 6)² ← distributing
x² + 4x + 4 + y² - 8y + 16 = y² - 12y + 36 ( subtract y² - 12y + 36 from both sides )
x² + 4x + 4 + 4y - 20 = 0 ( subtract x² + 4x + 4 from both sides )
4y - 20 = - x² - 4x - 4 ( add 20 to both sides )
4y = - x² - 4x + 16 ( divide through by 4 )
y = - [tex]\frac{1}{4}[/tex] x² - x + 4, that is
f(x) = - [tex]\frac{1}{4}[/tex] x² - x + 4 → B
Answer:
Option B
Step-by-step explanation:
Given that a parabola has a focus at (−2, 4) and a directrix of y = 6.
We have to find the equation of the parabola in std form
We know that a parabola is a conic section in which all points are equidistant from the focus and vertex.
Let (x,y) be any point on the parabola
Distance of (x,y) from the focus =[tex]\sqrt{(x+2)^2+(y-4)^2}[/tex] ...i
Distance of (x,y) from directrix = difference in y coordinate = [tex]|y[-6|[/tex]...ii
Since i = ii, square and equate both
[tex](x+2)^2+(y-4)^2=(y-6)^2\\x^2+4x+4 -8y+16 = -12y+36\\4y=-x^2-4x+16\\y = \frac{-1}{4} d^2-x+4[/tex]
Hence option B is right.

Answer: I think the answer is -x + y.
Step-by-step explanation:I think this is the answer because you first start off by distributing all the variables inside the parenthesis by the negative sign which would give you -x+2y-y. After that, you would have to subtract 2y-y because they share the same variable and you must have a SIMPLIFIED ANSWER. So with that said, your overall answer should be -x+y.

8,146 x 121
81,477 x 1,217
Answer:
8,146 x 121
Step-by-step explanation:
This is a problem in which you need to measure your understading of "orders of magnitude."
If the estimated answer is [tex]800000[/tex] that means that we are looking at a multiplication in the "order of" [tex]8*10^5[/tex]
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have [tex]8146*12[/tex] that would be "of the order of" [tex]8*10^3[/tex] times [tex]10^1[/tex]. So the whole multiplication would "of the order of" [tex]8*10^4[/tex] or near [tex]80000[/tex]
The correct answer, 8,146 x 121, is because it's "of the order of" [tex]8*10^3[/tex] times [tex]10^2[/tex] and the gives us the [tex]8*10^5[/tex] we need.

2. Two angles are supplements. They're equal in measure. Find both angles.
3. The supplement of an angle is three times the complement of the angle. Find the angle.
4. The supplement of an angle is 12 less than twice the angle. Find both angles.
Step-by-step explanation:
Supplementary angles equal 180°
1. Let the two angles be x and y
then y = 4x + 10
x + y = 180
x + (4x + 10) = 180
5x + 10 = 180
5x = 180 - 10
5x = 170
x = 170 / 5
x = 34
x = 34y = 146
2. if the two angles are equal then divide 180 by 2 to get 90
3. 180 - x = 3(90 - x)
180 - x = 270 - 3x
2x = 90
x = 45
4. 180 - x = 2x - 12
180 - 12 = 2x + x

Explanation:The equation that could be solved using the graph above is x2 - 2x + 1 = 0. This is because the graph intersects the x-axis at the point where y=0, and this represents the solutions to the equation.
If we solve the equation x2 - 2x + 1 = 0 using factoring or the quadratic formula, we would find that the solutions are x=1 and x=1. These are the same x-values where the graph intersects the x-axis on the graph provided.
