Using Reflection, ADP and BCP are the same.
If line PD is equal to line PC, angle 1 is equal to angle 2 and angle 3 is equal to angle 4, then line AP is equal and a reflection of line BP, line AD is also equal and a reflection of line BC
In reflected angles, the sides and angles of the shape are not altered.
The original image and reflected shape above are same size and shape therefore triangle ADP and BCP are the same.

Given the information in the question, in three years, the age of Alica would be 53.
What are fractions?A fraction is a non-integer. It is made up of numerators and denominators. An improper fraction is a fraction where the numerator is larger than the denominator. An example is 5/2/
What will be Alicia's age in 3 years?The first step is to determine Jessica's age in 5 years : 17 + 5 = 22
The second step is to determine Alica's age in 5 years : 5/2 x 22 = 55
Now, subtract 2 from 55: 55 - 2 = 53

Kyra went to the grocery store on Monday and bought 5 apples and 2 oranges for a total of $3.45. On Thursday she bought 3 oranges and 7 apples for a total of $4.90. How much do the apples and oranges cost?
Answer:
The apples and oranges cost .49 cents each
Step-by-step explanation:
When we do 5 + 2 we get 7, 7 is our number of apples and oranges combined.
Next we do 3.45 divided by 7 and get .49
When we do the same for thursday, we get the same answer which confirms our answer.
7th Grade Math) 6. A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation 350 = 12(x + 20) to represent this situation. Solve the equation for x. Show your work or explain your answer. Write your answer as a sentence that describes what the variable x represents. Enter your answers and your work or explanation in the box provided.
Answer:
x=9.167
Step-by-step explanation:
12x+240=350
350-240 because you are getting rid of 240 to get 12x by itself so you must do it on the other side.
12x=110, then you do 12x/12 and 110/12
x=9.167
Answer: Approimately $9.16
Step-by-step explanation:
In this problem, you have to solve for x variable.
1. Distribute the 12 to the x + 20 which is 12x + 240
2. Subtract 240 from both sides so 350 - 240 is 110.
3. Now your equation is 110 = 12x
4. Divide 12 on both sides. But 12 doesn't go into 110 perfectly.
5. 110 divided by 12 is approximately 9.16.
The x represent how much the student has earn extra to get $350 in 12 months. The student has to earn 9.16 dollars every month on top of the 20 dollars.

Which of the following shows the correct first step to solve x^2 - 16x = -21 by completing the square?
A)x^2 - 16x + 64 = -21
B) x^2 - 16x + 64 = -21 + 64
C) x^2 - 16x + 16 = -21 + 16
D) x^2 - 16x + 8 = -21 + 8
Answer:
I believe the answer would be B) x^2 - 16x + 64 = -21 + 64
Step-by-step explanation:
When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.
Ultimately, with it factored, the answer will be (x-8)^2
Barrett is 5 years less than half Cayden’s age. If Barrett is 11 years old, what is Cayden’s age?
(Someone help I’ve done this problem multiple times and I keep getting different answers)
The age of Cayden is given by the equation C = 32 years old
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the age of Cayden be C
Let the age of Barret be B = 11 years old
And , Barrett is 5 years less than half Cayden’s age
B = ( C / 2 ) - 5
On simplifying the equation , we get
11 = ( C / 2 ) - 5
Adding 5 on both sides , we get
16 = C / 2
Multiply by 2 on both sides , we getr
C = 32 years old
Therefore , the value of C is 32 years
Hence , age of Cayden is 32 years

The table below shows the value of a car during certain years . Using an exponential model , write an equation for the curve of best fit, then estimate the value of the car in 2016 .
The exponential function that gives the value of the car in t years after 2008 is:
[tex]A(t) = 27500(0.88)^t[/tex].
Using the function, the estimate for the value of the car in 2016 is of $9,900.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem:
The initial value is of A(0) = 27,500.Considering the first year change, we have that 1 - r = 24200/27500 = 0.88.Hence, the equation is:
[tex]A(t) = 27500(0.88)^t[/tex]
2016 is 8 years after 2008, hence the value of the car will be given by:
[tex]A(8) = 27500(0.88)^8 = 9900[/tex]

What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let y represent the value of the car after x years after 2008, hence:
at x = 0, y = 27500
27500 = ab⁰
a = 27500
At x = 1, y = 24200, hence:
24200 = 27500b¹
b = 0.88
y = 27500(0.88)ˣ
In 2016, x = 8, hence:
y = 27500(0.88)⁸ = 9890
The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890

Answers:

(1, 0) and (0, –5)
(2, 5) and (1, 0)
(3, 10) and (2, 15)
Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
Which equation best represents the relationship between x and y in the graph?
Answer:
C is your correct answer : y = 2x + 3
Step-by-step explanation:
Your answer choices are all in slope-intercept form.
Slope-Intercept Form: y=mx+b
First, you need to find the y-intercept.
Coordinate Point: (0,3) is your y-intercept.
Now, you need to find the slope.
This slope is positive.
There's another point (1,5).
This point is important because you can start at your y-intercept and rise and run to get to (1,5).
You have to rise up 2 and go over to the right 1.
2/1 is your slope but simplified is 2.
Your formula: y = 2x + 3
C is your correct answer
1. Avenue A runs parallel to Avenue B, and Avenue C runs diagonally across the two streets. Use the marked angles to write and solve an equation to find the value of x. 10x + 6 Avenue A 6x – 18 Avenue C Avenue B
The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12.
How to determine the value of x from a system of angles
In this question we must apply all Euclidean theorems of angles between two parallel lines cut by a third diagonal line. The internal angle between avenues B and C equals 6 · x - 18 and the external angle between avenues A and C equals 10 · x + 6.
By alternate internal angles between parallel lines we infer the measure of the internal angle between the avenues A and C equals 6 · x - 18, and definition of supplementary angles we have the following expression:
(6 · x - 18) + (10 · x + 6) = 180
16 · x - 12 = 180
16 · x = 192
x = 12
The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12. [tex]\blacksquare[/tex]
