The graph of f(x) = x| is shifted to the right 8 units, down 3 units.
The graph of f(x) = x| is shifted to the left 8 units, up 3 units.
The graph of f(x) = x| is shifted to the right 8 units, up 3 units.
Answer:
A. The graph of f(x) = |x| is shifted to the left 8 units, down 3 units.
Step-by-step explanation:
We are given,
The transformed function is [tex]f(x)=|x+8|-3[/tex].
Now, the parent function is [tex]f(x)=|x|[/tex].
So, we have,
When the parent function is shifted 8 units to the left, the function is [tex]|x+8|[/tex].
This function when translated 3 units downwards gives [tex]f(x)=|x+8|-3[/tex].
Thus, we get,
The parent function f(x)=|x| is translated 8 units to the left and 3 units downwards.So, option A is correct.

he value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after 2017. Write a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650. Do not use any dollar signs in the inequality. Write the inequality in standard form.
Answer:
[tex]300(1.05)^x\geq 650[/tex]
Step-by-step explanation:
Since, the initial value of the basketball = $ 300
Annual rate of interest = 5 %
Let the basket ball after x years is worth at least $ 650,
⇒ The cost of basketball after x years ≥ 650
[tex]\implies 300(1+\frac{5}{100})^x\geq 650[/tex]
[tex]\implies 300(1+0.05)^x\geq 650[/tex]
[tex]\implies 300(1.05)^x \geq 650[/tex]
Which is the required inequity.

Alvin’s age is two times Elga’s age. The sum of their age is 60. What is Elga’s age?
x = Elgas age
2x = Alvins age
x +2x = 60
3x =60
x = 60/3 = 20
Elga is 20 years old
Final answer:
By setting Elga's age as x and establishing an equation based on the given relationship and sum of their ages, we calculated Elga's age to be 20 years old.
Explanation:
To determine Elga's age, we will use the information given:
1. Alvin's age is two times Elga's age.
2. The sum of their ages is 60.
Let's define Elga's age as x. Then, Alvin's age would be 2x since it is two times Elga's age. The sum of their ages can be written as the following equation:
x + 2x = 60
This simplifies to 3x = 60. To find Elga's age, we divide both sides by 3:
3x / 3 = 60 / 3
x = 20
Therefore, Elga's age is 20 years old.

What is the missing term? (10x-4x^2)-(7x+?)=3x-6x^2
The given problem is =
[tex]( 10x-4x^{2} )-(7x+?)=3x-6x^{2}[/tex]
Lets suppose the missing term to be T
So equation becomes:
[tex]10x-4x^{2} -7x-T=3x-6x^{2}[/tex]
[tex]T=10x-4x^{2} -7x-3x+6x^{2}[/tex]
[tex]T=2x^{2}[/tex]
Hence, the missing term is [tex]2x^{2}[/tex]
This figure shows the nose cone of a rocket used for launching satellites. The nose cone houses the satellite until the satellite is placed in orbit. What is the volume of the nose cone?
45 cubic feet
60 cubic feet
90 cubic feet
180 cubic feet
Thank you :)
Answer:
[tex]45\pi\ ft^3[/tex]
Step-by-step explanation:
The volume of the cone can be calculated using formula
[tex]V_{cone}=\dfrac{1}{3}\cdot \pi r^2\cdot H,[/tex]
where [tex]r[/tex] is the radius of the base circle and [tex]H[/tex] is the height of the cone.
Since [tex]r=3\ ft[/tex] (half of the diameter given in the diagram) and [tex]H=15\ ft,[/tex] then
[tex]V_{cone}=\dfrac{1}{3}\cdot \pi \cdot 3^2\cdot 15=45\pi\ ft^3.[/tex]
divide -2x^3-5x^2+4x+2 by x+2
Final answer:
The detailed answer explains how to divide a polynomial by another using long division method.
Explanation:
To divide -2x³-5x²+4x+2 by x+2, we will perform polynomial long division:
-2x³-5x²+4x+2 / x+2
Start by dividing the leading terms: -2x³ / x = -2x². Multiply x+2 by -2x² to get -2x³-4x². Subtract this from -2x³-5x² to get x². Bring down the 4x next. Continue the process and you will get a quotient of -2x²+x-2 with a remainder of 6.

Which number can each term of the equation be multiplied by to eliminate the decimals before solving? –m + 0.02 + 2.1m = –1.45 – 4.81m A)0.01
B)0.1
C)10
D)100
since the 2 in 0.02 is in the hundredths place, you need to multiply that by 100 to eliminate the decimal, then you would need to multiply the other numbers by 100 as well
Answer is D) 100
The decimals place in a number can be shifted right or left by multiplying or dividing by powers of 10 respectively
The option which gives the number that will multiply each term of the equation -m + 0.02 + 2.1·m = -1.45 - 4.81·m to eliminate the decimals before solving, is option D)
D) 100
Reason:
The given expression is presented as follows;
-m + 0.02 + 2.1·m = -1.45 - 4.81·m
The number that can multiply the terms to eliminate the decimals before solving
Solution;
The number of decimal places to which the coefficient and constant values are given = 2 decimal places
Therefore, to eliminate the decimal places, the decimal point of each term has to be moved two places to the right
To move decimal points to the right x number of places is given by multiplying the number by 10ˣ
Therefore, to move the decimal point two places to the right so as to eliminate the decimal point, by multiplicative property of equality, we have;
10² × (-m + 0.02 + 2.1·m) = 10² × (-1.45 - 4.81·m)
10² = 100, therefore, we have;
100 × (-m + 0.02 + 2.1·m) = 100 × (-1.45 - 4.81·m)
-100·m + 2 + 2,100·m = -145 - 481·m
Therefore, the number the equation, -m + 0.02 + 2.1·m = -1.45 - 4.81·m, is to be multiplied by is 100

Is it possible to remove ten unit cubes from a 3 by 3 by 3 cube made from 27 unit cubes so that the surface area of the remaining solid is the same as the surface area of the original 3 by 3 by 3 cube? In how many different ways can this be done?
I removed all eight corners, leaving the total area unchanged.
I removed the central cube of the top surface obtaining an increase of the surface area with four units.
I removed one cube from the middle of an edge at the top (any of the four remaining) and I arrived at a figure with ten cubes less then the original one but with the same surface area.
https://nrich.maths.org/787/solutionThe cube can be removed from the top middle and from the center if a 3 by 3 by 3 cube is made from 27 unit cubes.
What is surface area?An object's surface area refers to the overall space that its surfaces occupy.
Given:
The dimensions of the cube are 3 by 3 by 3
Calculate the surface area of the cube as shown below,
Surface area = 6 × side²
Surface area = 6 × 3²
Surface area = 6 × 9
Surface area = 54
I eliminated each of the eight corners, leaving the entire space untouched.
I deleted the top surface's central cube to increase the surface area by four units.
I started with a shape that was ten cubes smaller than the original one but had the same surface area after removing one cube from the center of one of the top edges (any of the four still there).
