What form is the equation below written in?
y= (x - 2)2 – 9
-Factored Form
-Standard Form
-Slope-Intercept Form
-Vertex Form
Answer:
Vertex FormStep-by-step explanation:
Vertex form of quadratic function with vertex (h, k) is y=a(x-h)²+k,
So y= (x - 2)² - 9 is vertex form with vertex (2, -9)

-2x + y = 0
x - y = -3
Answer:
The value of x is 3 and y is 6.
Step-by-step explanation:
You can solve this simultaneous equation by elimination method :
[tex] - 2x + y = 0 - - - (1)[/tex]
[tex]x - y = - 3 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex] - 2x + y + x + (- y) = 0 + ( - 3)[/tex]
[tex] - x = - 3[/tex]
[tex]x = 3[/tex]
[tex]substitute \: x = 3 \: into \: (2)[/tex]
[tex](2)⇒[/tex]
[tex]3 - y = - 3[/tex]
[tex] - y = - 6[/tex]
[tex]y = 6[/tex]

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?
Answer:
$110Step-by-step explanation:
Step one:
we are told that the cost of the sofa is $275
also, he sells it for 40% more of the cost price
let us find 40% of $275
=40/100*275
=0.4*275
=110
=$110
Step two:
This means that the selling price is 275+110
=$385
profit = selling price- cost price
profit=385-275
profit=$110

Which clues would indicate that you need to find volume? Check all that apply. an object that is filled covering the outside of an object an object that is solid cubic units square units
ANSWER: 1,3,4
The options are as follows
(1) An object that is filled
(2) Covering the outside of an object
(3) An object that is solid
(4) Cubic units
(5) Square units
Answer:
(1) An object that is filled
(3) An object that is solid
(4) Cubic units
Step-by-step explanation:
Clues that applies
(1) An object that is filled: By filling means that object has that amount of volume that is being filled completely.
(3) An object that is solid is likely a clue to finding the volume of an irregularly shaped solid.
(4) Cubic units, volume is measured in cubic units.
Clues that Doesn't Apply
(2) Covering the outside of an object is a clue to finding the surface area of an object.
(5) Square units is a measure of area not volume.

what is the vertex of y=x^2 +x-6?
y =(x+ 1/2 ²- 25/4 . explanation. y=x²+x=6 . complete the square.
y=x²+x+(1/2)² -6 - 1/4 . simplify
y=(x+1/2²)- 25/4 in the vertex form

they are hired in the ratio 1:2
so do 1+2=3
then divide 54 by 3 to get 18
do 18 multiplied by 2 to get the number of CNAs
and 18 multiplied by 1 to get the number of nurses

Standard Form: ax² + bx + c = 0Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]Step-by-step explanation:
Step 1: Define equation
6x² - 13x + 6 = 2x²
Step 2: Rewrite in Standard Form
Subtract 2x² on both sides: 4x² - 13x + 6 = 0Step 3: Define
a = 4
b = -13
c = 6
Step 4: Solve for x/roots
Substitute: [tex]x=\frac{13\pm\sqrt{(-13)^2-4(4)(6)} }{2(4)}[/tex]Exponent: [tex]x=\frac{13\pm\sqrt{169-4(4)(6)} }{2(4)}[/tex]Multiply: [tex]x=\frac{13\pm\sqrt{169-96} }{8}[/tex]Subtract: [tex]x=\frac{13\pm\sqrt{73} }{8}[/tex]And we have our final answer!
F(x)=2/3x+9x
What is the value of f(12)?
Answer:
116
Step-by-step explanation:
To find f(12), plug in 12 as x in the equation:
f(x) = 2/3x + 9x
f(12) = 2/3(12) + 9(12)
f(12) = 8 + 108
= 116
So, f(12) = 116

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation
Answer:
Your system of inequalities is:
x + y ≥ 35
15x + 8y ≥ 350
Step-by-step explanation:
Let x = number of boxes of small books and let y = number of boxes of large books.
Since John needs to pack at least 35 boxes:
(number of boxes of small books) + (number of boxes of large books) (is at least) 35
x + y ≥ 35
Since John needs to pack at least 350 books:
(number of small books packed) + (number of large books packed) (is at least) 350
(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350
15x + 8y ≥ 350
How many 1/8-inch pieces of ribbon can be cut from a piece of ribbon that is 3/4 inch long? It can't be a fraction, sadly :')
Answer:
6 pieces.
Step-by-step explanation:
3/4 divided by 1/8
= 3/4 / 1/8
