What is the vertex form of function?The vertex of a parabola is the point at which the parabola passes through its axis of symmetry.
The standard equation which represents the vertex form of the function is;
[tex]\rm f(x) =(x-h)^2+k^2[/tex]
Where h and k are vertexes of the given parabola.
The function is in vertex form;
[tex]\rm f(x)= 7 x^2 + 42 x\\\\ f(x) = 7 ( x^2+ 6 x ) \\\\ f(x)= 7 ( ( x^2+ 6 x + 9 ) - 9 ) \\\\ f(x)= 7 ( x + 3 )^2 - 63[/tex]

Match the sides of the right triangle
Help
Answer:
A right-angled triangle has 2 legs and a hypotenuse.
In trigonometry, the 2 legs are labelled opposite and adjacent, and this labeling is interchangeable, depending on which interior angle we are working with.
the hypotenuse is always the side opposite to the 90° angle and is therefore always the longest side. So for this triangle, the hypotenuse is line LM.
For example, If we look at angle L, the line KL is adjacent (next) to it, and line KM is opposite to it. However, if we look at angle M, the line KM is adjacent to it, and the line KL is opposite it. Remember, the hypotenuse doesn't change.
Therefore:
Angle adjacent to side KL = angle L
Angle adjacent to side KM = angle M
Side opposite to angle L = side KM
Side opposite to angle M = side KL
Hypotenuse = side LM
Trains Two trains, Train A and Train B. weigh a total of 196 tons. Train A is heavier than Train B. The
difference of their weights is 60 tons. What is the weight of each train?
Answer:
Train A = 128
Train B = 68
Step-by-step explanation:
We can set up a system of equations for this problem
Let A = # of tons of Train A
Let B = # of tons of Train B
A + B = 196
A = B + 60
Now, we plug in A for the first equation, using substitution
(B+60) + B = 196
2B + 60 = 196
Subtract 60 from both sides
2B = 136
Divide both sides by 2
B = 68
Plug in 68 for B in the 2nd equation
A = 68 + 60
A = 128
Checking work: 128 + 68 = 196 :D hope this helped

Find the zeros of the function f(x)=x^2-2x-2.f(x)=x2−2x−2. Round values to the nearest hundredth (if necessary).
By definition, the zeros of the quadratic function f(x) = x² - 2x - 2 are 2.732 and -0.732.
Zeros of a functionThe points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.
That is, the zeros represent the roots of the polynomial equation that is obtained by making f(x)=0.
In summary, the roots or zeros of the quadratic function are those values of x for which the expression is equal to 0. Graphically, the roots correspond to the abscissa of the points where the parabola intersects the x-axis.
In a quadratic function that has the form:
f(x)= ax² + bx + c
the zeros or roots are calculated by:
[tex]x1,x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]
This caseThe quadratic function is f(x) = x² - 2x - 2
Being:
a= 1b= -2c= -2the zeros or roots are calculated as:
[tex]x1=\frac{-(-2)+\sqrt{(-2)^{2} -4x1x(-2)} }{2x1}[/tex]
[tex]x1=\frac{2+\sqrt{4 +8} }{2}[/tex]
[tex]x1=\frac{2+\sqrt{12} }{2}[/tex]
[tex]x1=\frac{2+3.464}{2}[/tex]
[tex]x1=\frac{5.464}{2}[/tex]
x1= 2.732
and
[tex]x2=\frac{-(-2)-\sqrt{(-2)^{2} -4x1x(-2)} }{2x1}[/tex]
[tex]x2=\frac{2-\sqrt{4 +8} }{2}[/tex]
[tex]x2=\frac{2-\sqrt{12} }{2}[/tex]
[tex]x2=\frac{2-3.464 }{2}[/tex]
[tex]x2=\frac{-1.462 }{2}[/tex]
x2= -0.732
Finally, the zeros of the quadratic function f(x) = x² - 2x - 2 are 2.732 and -0.732.

What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Players earn points for successful tosses and lose points for missed tosses.
Results for two players are shown in the table.
Number of successful toss, number of missed toss and total number of points for Player 1 and Player 2 are given in the table.
Let's assume that:
Each successful toss = +x points
Each missed toss = -y points
From the given table:
4x - 3y = 6 ...(i)
5x - 5y = 5
x - y = 1
y = x - 1
Substituting y in eq(i)
4x - 3(x - 1) = 6
4x - 3x + 3 = 6
x = 3 and y = 2
Hence, the correct statement is each successful toss is worth 3 points.

Natalie saves $35 each month to buy a DVD player. The DVD player
costs $197.99. Will Natalie be able to buy the DVD player in 5 months?
If not, how much more money does she need?
Multiply amount she saves per month by 5 months:
35 x 5 = $175
$175 is less than the price of the player so she won’t have enough to buy it.
197.99 - 175 = $22.99
She needs $22.99.more

At a carnival, Jack and his brother collected 53 pieces of candy all together. Each of them
ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left. How many pieces
did Jack's brother have left?
The number of candies Jack's brother has left if Jack and his brother collected 53 pieces of candy altogether. Each of them ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left is 24.
What is subtraction?The process of finding the difference by subtracting a matrix, vector, or another variable from another in accordance with preset principles.
Given:
The total no of candies = 53,
The no of candy eaten = 5 pieces each,
The no of candies Jack had = 19,
Now, The no of candies Jack's brother have left = The total no of candies - The no of candy eaten + The no of candies Jack had
Substitute the values,
The no of candies Jack's brother have left = 53 - 5 × 2 + 19 = 24,
Therefore, the number of candies Jack's brother has left if Jack and his brother collected 53 pieces of candy altogether. Each of them ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left is 24.

Three friends order a pizza for $14, a bottle of soda for $3 and a large piece of cake to share for $4. The friends want to evenly split the costs. How much does each friend owe? Use mathematics to justify your answer.
Step-by-step explanation:
Total = $14+$3+$4
Total = $21
Each friend owe = $21/3
So, each friend owe $7
Answer:
$7 each
Step-by-step explanation:
Let's determine the total cost first to see how the friends can divide the cost.
The total cost is $21. 14 for a pizza, 3 for the soda, and 4 for the cake.
There are 3 friends and 21 goes evenly in 3. So 21 divided by 3 is $7 per person.
Is x=4 a solution to the equation 9x = 32 + x?
Answer:
yes
Step-by-step explanation:
because 9*4=36 and well it's 36=32*? so 36-32 is 4
So well the solution is x=4
Answer:
Yes, it is.
Explanation:
For x = 4 to be a solution of the given eqⁿ, it must satisfy it. That is,
9x = 32 + x => 8x - 32 = 0
=> f(x) = 8x - 32
At x = 4,
f(4) = 8(4) - 32 = 32 - 32 = 0
Since, f(4) = 0, thus, x = 4 is a solution to the given eqⁿ.
There are 120 candy worms in a bag of Trolli worms. You accidently spilled 1/5 of them in the hallway and
they got trampled. Then you gave 1/6 of your remaining candy worms to your friend. How many candy
worms do you have left?
Answer
80
Step-by-step explanation:
1/5 of 120 is 24
120 - 24 because you dropped 1 /5
gives you 96
then you give 1/6 of what you have left to your friend and that means giving 16 candies to your friend so 96-16
and that gives you 80 candies remaining

The balance of a loan is $2,570 in January, and the monthly payment is $125.50. The relationship between the loan balance, y, and the number of monthly payments made since January, x, can be represented by the equation y = 2,570 - 125.50x. In what months does the loan balance, y, meet the condition, $1,600 < y < $2,000?
Answer:
June, July, and August.
Step-by-step explanation:
1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.

Answer:
n = −0.7, so the second one is the answer
Step-by-step explanation:
−2n + 1.8 = 3.2
Step 1: Subtract 1.8 from both sides.
−2n + 1.8 − 1.8 = 3.2 − 1.8
−2n = 1.4
Step 2: Divide both sides by -2.
-2/-2 = 1.4/-2
