The parent function is
[tex]y = |x| [/tex]
This is the base of the absolute value functions.
It has its vertex at the origin.
The transformed function is

You start driving north for 3 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straight line distance from your starting point?
The straight line distance is 5 miles from starting point.
Step-by-step explanation:
Driving 3 miles north and 4 miles east and then the straight line distance will form a right angled triangle.
Where;
One leg = a = 3 miles
Other leg = b = 4 miles
Hypotenuse = c
Using Pythagoras theorem;
[tex]a^2+b^2=c^2\\(3)^2+(4)^2=c^2\\9+16=c^2\\c^2=25[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{25}\\c=5[/tex]
The straight line distance is 5 miles from starting point.

If the length of a pool is 8 more than twice the width and the total area is 960 square feet, find the length and width of the rectangular landscape element.
Answer:
l=48, w=20
Step-by-step explanation:
Let the width of the pool be w feet, then the length will be:
[tex]l = 2w + 8[/tex]
The area of the pool is 960 square feet.
This means that:
[tex]w(2w + 8) = 960[/tex]
Expand and rewrite in standard form to get:
[tex]2 {w}^{2} + 8w - 960 = 0[/tex]
[tex] {w}^{2} + 4w - 480 = 0[/tex]
[tex]{w}^{2} + 24w - 20w- 480 = 0[/tex]
[tex]{w}(w+ 24) - 20(w + 24) = 0[/tex]
Factor to get:
[tex](w+ 24)(w - 20) = 0[/tex]
[tex]w = - 24 \: or \: w = 20[/tex]
We discard the negative value because magnitude is positive.
This means
[tex]l = 2 \times 20 + 8 = 48[/tex]

Answer:
c=3
Step-by-step explanation:
First simplify like terms.
1+4c=7+2c
1+2c=7 (subtract 2c from both sides)
2c=6 (subtract 1 from both sides)
c=3 (divide by 2)
CHECK:

Yes!
Answer: [tex]c=3[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation:
[tex]4c+1=2c+7[/tex]
Step 2: Subtract 2c from both sides:
[tex]4c+1-2c=2c+7-2c[/tex]
[tex]2c+1=7[/tex]
Step 3: Subtract 1 from both sides.:
[tex]2c+1-1=7-1[/tex]
[tex]2c=6[/tex]
Step 4: Divide both sides by 2:
[tex]2c/2=6/2[/tex]
Get your answer:

if 2a+b=3,find the value of 8a³+b³+18ab
Answer:
531.
Step-by-step explanation:
Let's assume 2(1) + 1 = 3
a = 1 and b = 1
Now we can plug that in
8(1)^3 + (1)^3 + 18(1)(1)
Then we need to multiply together
8^3 + 1^3 + 18
Then do the powers
512 + 1 + 18
Then add them together

Answer:
27
Step-by-step explanation:
A sum of cubes factors as
a³ + b³ = (a + b)(a² - ab + b²)
Factor the sum of cubes 8a³ + b³
8a³ = (2a)³, thus
8a³ + b³
= (2a)³ + b³
= (2a + b)(4a² - 2ab + b²)
We now have the right side as
(2a + b)(4a² - 2ab + b²) + 18ab ← substitute 2a + b = 3
= 3(4a² - 2ab + b²) + 18ab
= 12a² - 6ab + 3b² + 18ab ← collect like terms
= 12a² + 12ab + 3b² ← factor out 3 from each term
= 3(4a² + 4ab + b²) ← perfect square
= 3(2a + b)² ← substitute 2a + b = 3
= 3 × 3²
= 3 × 9
= 27
Find the missing angle measure below:
Answer:
81
Step-by-step explanation:
ANGLES in a TRIANGLE add up to 180
In the Triangle you have 65 and 34
Add them together = 99
Subtract the total from 180
180 - 99 = 81
Answer:
81 degrees
Step-by-step explanation:
The angles of the triangle always add up to 180.
SO you'd do 65+34 which equals 99.
NOW you do 180-99 which equals 81
So you're missing angle would be 81 degrees
The queen had 300 servants. there were 10 more butlers than cooks. the number of cooks was twice the number of maids. how many maids worked at the queen palace?
The no. of maids who worked at the queen's palace is 58.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The queen had 300 servants. there were 10 more butlers than cooks. The number of cooks was twice the number of maids.
Assuming the no. of maids to be 'x', therefore no. of cooks is 2x and the no. of butlers is (2x + 10).
∴ x + 2x + (2x + 10) = 300.
5x = 290.
x = 58.

16 store cashiers work average 21 hours per week and paid $8.25 per hour . after store manager hires 2 additionsl cashiers each cashier will be paid .25 more per hour and will work an average of 1.5 fewer hours per week. what will be the change in total amount of money the cashiers are paid each week?
Answer:
The change in total amount of money the cashier are paid each week will be $331.5.
Step-by-step explanation:
16 store cashiers work average 21 hours per week and paid $8.25 per hour.
Now, the store manager hires 2 additional cashiers each cashier will be paid 0.25 more per hour and will work an average of 1.5 fewer hours per week.
Therefore, the two additional cashiers will be paid $8.50 per hour and will work an average of (21 - 1.5) = 19.5 hours per week.
So, the change in the total amount of money the cashiers are paid each week will be (2 × 19.5 × 8.5) = $331.5. (Answer)

marco wants to buy 2 books that cost 20$ each. He can save $5 a week. Draw siagrama and write equations to find how many weeks it will take hime to save enough money to buy the books.
Answer: He needs to wait 8 weeks.
Step-by-step explanation: 5•8 equals 40. 2 books, 20$ each and add them together, 40!
To determine the number of weeks Marco needs to save $40 to buy two books at $20 each, an equation can be set up based on his weekly savings of $5. Solving the equation 5 × w = $40 gives us w = 8, meaning Marco will need to save for 8 weeks.
Explanation:The problem given is about Marco who wants to buy two books, each costing $20. He can save $5 a week. To calculate how many weeks it will take for Marco to save enough to buy the books, we can set up an equation. First, we need to determine the total cost of the books:
Cost of one book = $20Cost of two books = 2 × $20 = $40Next, let’s set up our equation. If Marco saves $5 each week, the total amount saved after w weeks will be 5 × w. We want this to be equal to the total cost of the books, so our equation will be:
5 × w = $40
To solve for w, we divide both sides by 5:
w = $40 / 5
w = 8
Therefore, it will take Marco 8 weeks to save enough money to buy the two books.

What did you have to multiply the first equation by, if anything?
What did you have to multiply the second equation by, if anything?
Answer:
cils Gabby bought a nens and Spencils
6 bills in the deposit were $10 bills.
Step-by-step explanation:
The total number of bills he gave the teller = 24 bills
x + y = 24 ------------(1)
Let,
x be the number of $5 bills.
y be the number of $10 bills.
The total bank deposit made using $5 and $10 bills are $150.
He deposits $5 bills and $10 bills. So, the equation can be framed as :
5x + 10y = 150 --------(2)
The question is asked for how many $10 bills were in the deposit,
Here 'y' is the number of $10 bills.
To solve for y value :
The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),
5x + 5y = 120
-(5x + 10y = 150)
-5y = -30
⇒ y = 30/5
⇒ y = 6
Therefore, there were 6 bills in the deposit that are $10 bills.

Write the explicit formula for the geometric sequence
The formula [tex]3(4^{n-1})[/tex] represents the geometric sequence.
Step-by-step explanation:
Step 1:
The value of [tex]a_{n}[/tex] is dependent on the value of n.
So n is independent while [tex]a_{n}[/tex] is dependent on n i.e. the value of [tex]a_{n}[/tex]depends on the value of n.
Step 2:
We substitute the values of n in the functions to check which function satisfies the values of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} = -4(3)^{n-1} = -4 (3^{3}) = -108.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} = 4(3)^{n-1} =-4 (3^{3}) = 108.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} =3(-4)^{n-1} = 3 (-4^{3}) = -192.[/tex] This does not equal the value of [tex]a_{n}[/tex].
If [tex]n = 4, a_{n} =3(4)^{n-1} = 3 (4^{3}) = 192.[/tex] This equals the value of [tex]a_{n}[/tex].
So the fourth formula represents the geometric sequence.

Answer:
The radius is 2.5 yards
The diameter is 5 yards
Step-by-step explanation:
We want to find the radius and diameter given that, the circumference of the circle is;
C=5π yards.
Recall that, the circumference of a circle is C=πd
This implies that:
[tex]5\pi = \pi \: d[/tex]
Divide both sides by π
[tex]5 = d[/tex]
To find the radius, divide the diameter by 2;
[tex]r = \frac{5}{2} = 2.5[/tex]
The radius is 2.5 yards
The diameter is 5 yards
