Answer:
y = 1/2x^2 - 2x - 1
Step-by-step explanation:
Vertex(2, - 3)
Equation of Parabola (In vertex form): y = a(x - h)^2 + k,
y = a(x - 2)^2 - 3
Substitute given point (0, -1) and solve for a:
y = a(x - 2)^2 - 3,
-1 = a(0 - 2)^2 - 3,
a = 1/2
Equation: y = 1/2(x - 2)^2 - 3 = 1/2(x^2 - 4x + 4) - 3 = 1/2x^2 - 2x + 2 - 3 = 1/2x^2 - 2x - 1,
y = 1/2x^2 - 2x - 1: Option C

b+1/3=2 Plz I need it, I will give you brainiest
Answer:
[tex]1\frac{2}{3} [/tex]
Answer:
b = 5/3
Step-by-step explanation:
Ok so,
b + 1/3 = 2
b + 1/3 - 1/3 = 2 - 1/3
now you have to find the common denominator which in this case is 3. so you multiply 2 with 3 giving you six so it should look like this
b = 2/3 - 1/3
b = 1/3

Answer:
9Step-by-step explanation:
Find the diagram attached
Using the similarity theorem
A F/F B = AG/GC
x+1/x+6 = x-1/x+3
Cross multiply
(x-1)(x+6) = (x+1)(x+3)
Expand
x²+6x-x-6 = x²+x+3x+3
5x - 6 = 4x+3
5x-4x = 3+6
x = 9
Hence the value of x is 9
A can of soup has the shape of a cylinder.
The diameter of the base of the can is
3.4 inches, and the height of the can is
4.5 inches. What is the volume of the can
rounded to the nearest tenth of a cubic
inch?
Answer:
Step-by-step explanation:
Height h = 4.5 inches
Radius r = 3.4/2 = 1.7 inches
Area of base = πr² = 2.89π square inches
Volume of cylinder = πr²h = 2.89π4.5 = 13.0 cubic inches
Answer:
The answer is 40.8
Step-by-step explanation:
The volume of a cone equals the area of a circle multiplied by the height
[tex]v = \pi \times {r}^{2} \times h \\ = 3.14 \times 1.7 \times 1.7 \times 4.5 \\ = 40.8[/tex]

Answer:
1. 3(x-4)-9= 3
3x-12-9=3
3x-21=3
3x=24
x=8
2. x=6
3. x=8
4. x=2
Answer:
Miscellaneous
Step-by-step explanation:
1. Distribute and simplify to get: 3x-12-9 = -3
Then combine like terms to get 3x-21 = -3
Add 21 on both side sto get 3x = 18
divide 3 on both sides to get x=6
2. x+5 = 11
Subtract 5 from both sides to get x = 6
3. 2x-3 = 13
Add 3 to both sides to get 2x = 16
Divide 2 from both sides to get x =8
4. 4(x+2) = 16
Distribute to get 4x+8 = 16
Subtract 8 from both sides to get 4x = 8
Divide 4 from both sides to get x=2

Answer:
y=x-4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)=(4-(-2))/(8-2)=(4+2)/6=6/6=1
slope is 1
y-y1=m(x-x1) where m=slope
y-(-2)=1(x-2)
y+2=x-2
y=x-2-2

Find the length of AD if AB = 24, DE = 8, and DC = 12.
a.8
b.12
c.14
d.10
HELP PLS
Answer:
AD = 12
Step-by-step explanation:
Find the diagram attached
From the given diagram, it can be inferred that;
AB = AD+DB and AD = DB
AB = AD + AD
AB = 2AD
AD = AB/2
Given that AB = 24
AD = 24/2
AD = 12
Hence the length of AD is 12

tim played 20 games of draughts he won 16 of those games.what fraction of the game did he win
b) he played 30more games he had then 68% of all his games how amny of 30 games did he win
Answers to both subparts are shown:
(A) The fraction of games Tim wins is 4/5.(B) Tim wind has 20 games when he plays 30 games.What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction.So, (A) fraction of the game Tim wins:
The number of games played is 20.The game won is 16.Then, the fraction will be:
16/204/5(B) Games Tim wins in 30 games.
The total number of games played is 30.The winning percentage is 68%.So, a number of games won:
30/100 × 680.30 × 6820.4Rounding off: 20Therefore, answers to both subparts are shown:

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
The proportion of scale model of the boat to the real boat is 1 : 5
Now ,
a)
The height of the real boat is 15 feet and the scale model is k inches
From the proportion , we get
1 / 5 = k / 15
Multiply by 15 on both sides , we get
k = 3 inches
b)
The scale model is 9 inches , and the real height is H
From the proportion , we get
5 / 1 = H / 9
Multiply by 9 on both sides , we get
H = 45 feet
Hence , the proportion is solved

Find all x-values for which f ( x ) = 2 for the function below.
{ ( - 3, 2 ), ( - 1, 0 ), ( - 3, 1 ), ( 2, - 3 ) }
how would i solve this please help
Answer:
x = -3Step-by-step explanation:
First let us get the equation of the coordinates
y-y0 = m(x-x0)
Using the coordinates ( - 3, 2 ), ( - 1, 0 )
m = 0-2/-1-(-3)
m = -2/2
m = -1
Substitute m = -1 and (-1, 0) into the formula
y - 0 = -1(x+1)
y = -x-1
f(x) = -x-1
Since f(x) = 2
2 = -x-1
-x = 2+1
-x = 3
x = -3
Hence the value of x is -3
What is the solution of the system of equations?
