The correct option D) Add 48 to 52 is the conjecture that describes for the 7th term in the sequence.
What is termed as the arithmetic progression?An arithmetic progression (AP) is just a sequence in which the differences between each successive term are the same.An arithmetic progression (AP) can be defined in two ways:An arithmetic progression is still a sequence in which the differences between each successive term are the same.An arithmetic progression is a sequence in which each term (except the first) is obtained by having to add a fixed number to the term before it.For the given question, the sequence is given as;
4, 20, 36, 52,
Where, the first term a₁ is 4.
Second term a₂ is 20 and,
Third term a₃ is 36
Common difference d for each case is;
d = a₂ - a₁
d = 20 - 4 = 16
d = a₃ - a₂
d = 36 - 20 = 16
as, common difference is same, the sequence is said to be in AP.
Then, the formula for finding the 7th term is -
a₇ = a₁ + 6d
a₇ = 4 + 6×16
a₇ = 100
Now, this 7th term from the options can be found as;
Add 48 to 52 = 100.
Thus, the conjecture that describes for the 7th term in the sequence is add 48 to 52.

20$ startup fee and a $5 monthly fee write an equation in slope intercept form that models
The slope intercept form of equation that models $20 startup fee and $5 monthly fee is y = 5x +20 , y is total fee and x is number of months
What is slope intercept form?The slope intercept form of an equation is y = mx + c
where y is y coordinate, x is x coordinate, m is the slope of the line and c is y intercept.
Let the total fee after x months be y
Then y is sum of startup fee and sum of all month's fee
For x months total monthly fees = 5(x)
Therefore the total fee after x months , y = 5x +20 which is same as slope intercept form y=mx+c
when x= 0 ⇒ y = 20 , startup fee
Thus, the equation in slope intercept form is y = 5x +20 ,where y is total fee and x is number of months.

Plot the intercepts to graph the equation.
2x-3y=6
Answer:
y - intercept is (0,2)
x - intercept is (3,0)
Step-by-step explanation:
This is standard form.
Let x = 0
2x + 3y = 6
2(0) + 3y = 6
3y = 6 Divide both sides of the equation by 3
y = 2
The y intercepts is (0,2)
Let y = 0
2x + 3(0) = 6
2x = 6 Divide both sides of the equation by 2
x = 3
The x intercept is (3,0)
Answer:
x-intercept (3, 0)
y-intercept (0, -2)
Step-by-step explanation:
Finding the intercepts:At x-intercept the y = 0. The line passes the x-axis.
2x -0 = 6
2x = 6
x = 6 ÷ 2
x = 3
x-intercept (3, 0)
At y-intercept, x = 0 . The line passes y-axis.
0 - 3y = 6
-3y = 6
y = 6 ÷ (-3)
y = (-2)
y-intercept (0 , -2)

Answer: x = 65
Step-by-step explanation:
1) First find the mini triangles, left and right angles
We will be calling the left one A and the right one B.
2) Next use triangle sum to find B.
62 + 50 + b = 180
b = 68
3) Use triangle sum again to find A.
53 + 80 + a = 180
a = 47
4) Use triangle sum to find the top mini angle.
47 + 68 + c = 180
c = 65
5) Since x is in the vertical angle of c, they are equal

A store owner mixes 2 lbs of candy that cost x dollars pound with 3 lb of candy that costs $1.50 per pound. she sells the mix for $2.50 per pound. how much did the 3lb of the second type cost the owner?
Algebraic equations are mathematical equations that consist of unknown variables. These unknown variables can be represented with any letter of the alphabet.
The cost of 2 pounds(lb) of the first type of candy is $8
Note that: x represents the cost per pound (lb) of the first type of candy
The Algebraic equation for the above statement is given as:
2lb × $x + 3 Ib × $1.50 = $2.50(2lb + 3lb)
2x + 4.5 = 12.5
Collect like terms
2x = 12.5 - 4.5
2x = 8
Divide both sides by 2
2x/2 = 8/2
x = 4
The cost of the 1 pound of first type of candy is $4
The cost of 2 pounds(lb) of the first type of candy is calculated as:

The coordinates of the orthocenter of triangle DEF are given as follows:
(6.67, -2).
How to find the orthocenter of a triangle?The orthocenter of a triangle is the point of intersection of the three altitude lines of the triangle.
Hence, we need to find two of the lines, and them find the intersection point between them, as the third line will necessarily intersect these lines at this point.
The midpoint of segment DE is:
(6, 1).
Which is the mean of the coordinates.
Vertex F is at point (8, -8), hence the slope of the line with these two points is:
m = (-8 - 1)/(8 - 2) = -9/2 = -4.5.
Hence:
y = -4.5x + b.
When x = 6, y = 1, hence we can find b as follows:
1 = -4.5(6) + b
b = 28.
Hence one line is:
y = -4.5x + 28.
The midpoint of segment EF is:
(8, -1.5).
Which is the mean of the coordinates.
Vertex D is at point (4, -3), hence the slope of the line with these two points is:
m = (-1.5 - (-3))/(8 - 4) = 0.375.
Hence:
y = 0.375x + b.
When x = 8, y = -1.5, hence we can find b as follows:
-1.5 = 0.375(8) + b
b = -4.5.
Hence the two lines that we have to find the intersection point is:
y = -4.5x + 28.y = 0.375x - 4.5.Then the x-coordinate of the orthocenter of the triangle is:
-4.5x + 28 = 0.375x - 4.5
4.875x = 32.5
x = 32.5/4.875
x = 6.67.
The y-coordinate of the orthocenter of the triangle is:
y = 0.375(6.67) - 4.5 = -2.

If the zeros or roots of the polynomial are given, then the standard form of the polynomial can be found.
That is, a, b and c are roots of the polynomial, then the polynomial will be of degree 3 since 3 zeros are there and the factors of the polynomial will be , x-a, x-b and x- c.
Then the polynomial is, (x-a)(x-b)(x- c) = x³-(a+b+c)x-abc

Herein we find the representation of a line set on a Cartesian plane. According to analytic geometry, line are represented by equations of the form y = m · x + b, where m, b are the slope and the y-intercept, respectively.
Both the values of the slope and the y-intercept can be found by knowing the location of two points lying on the line. If we know that (x₁, y₁) = (0, - 6) and (x₂, y₂) = (4, - 7), then we find the following system of linear equations:

Next, you decide to pay with a $20.00 bill. How much change will you receive after paying for your video game?
Using simple linear equations we calculate that the change left will be $6.24 .
The equals sign is used to indicate that two expressions on each side of the equal sign are equal in the many mathematical formulas that are utilized to form an equation.
Depending on the language, the definition of the word equation and its cognates may change slightly.The first step in solving a variable equation is to determine the precise values of the unknown variables that lead to the provided equality. The equation's solutions, often referred to as the variables for which the equation must be solved, are the values of the unknowable variables that satisfy the equality.Let the change received be x.
Therefore let us construct an equation for the situation
cost of game + tax + change = 20
or, 12.98 + 0.78 + x = 20
or, 13.76 + x = 20
or, x = 6.24

Answer:
x = 60
Step-by-step explanation:
(2x + 15)° and 135° are corresponding angles and are congruent , then
2x + 15 = 135 ( subtract 15 from both sides )
2x = 120 ( divide both sides by 2 )
x = 60
Answer:
x = 60
Step-by-step explanation:
The two angles are corresponding. This means that both of the angles are congruent (same). So, you set both of them equal to each other. That means to do 2x + 15 = 135. You do basic algebra and then you get 60 for x. Hope this helps!
