Answer:
Option A is the correct
Step-by-step explanation:
a=d+c/b
Now we have to solve for d
Multiplying b on both sides
a*b=d+c/b*b
ab=d+c
ab-c=d

Please help, (AP is arithemtic progression)
Answer:
p = 8
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₉ = 4 + 5p and d = 5, then
a₁ + 8d = 4 + 5p, that is
a₁ + 8(5) = 4 + 5p
a₁ + 40 = 4 + 5p ( subtract 40 from both sides )
a₁ = 5p - 36
a₂ = 5p - 36 + 5 = 5p - 31
a₃ = 5p - 31 + 5 = 5p - 26
a₄ = 5p - 26 + 5 = 5p - 21
Given that the sum of the first 4 terms = 7p - 10, then
5p - 36 + 5p - 31 + 5p - 26 + 5p - 21 = 7p - 10, that is
20p - 114 = 7p - 10 ( subtract 7p from both sides )
13p - 114 = - 10 ( add 114 to both sides )
13p = 104 ( divide both sides by 13 )
p = 8

Solve for x? and the lengths missing side
Answer:
X = 15, the missing length (c) is 10
Step-by-step explanation:
Using Pythagorean’s Theorem we know that a^2 + b^2 = c^2
We have side a and b, represent a as 6 and b as 8.
We have 6^2 + 8^2 = c^2
Which equals 100 = c^2
10 = c
Side C is 10, and (x - 5) = 10
X = 15
Please mark BRAINLIEST!
Answer: x ≅ 15.95
Step-by-step explanation:
Use the pythagorean theorem for right triangles x^2 + y^2 = s^2
6^2 = 36
8^2 = 64
(x - 5)^2 requires FOIL. Unfortunately Im going to do this on paper. Its essentially First Outside Inside Last. i got x^2 - 10x + 25
Lets now add 36 and 84 and make it equal to the trinomial we just got.
[tex]120=x^2-10x+25[/tex]
Now lets subtract 120 from both sides to get:
[tex]0=x^2-10x-95[/tex]
You could complete the square, I think. But im going to use the quadratic formula. [tex]\frac{-b +/- \sqrt{b^2-4ac} }{2a}[/tex]Im going to calculate this on paper for simplicity's sake. Im getting an answer of about [tex]\frac{10(+/-)21.909}{2}[/tex]
Solve by adding and then solve by subtracting to get x ≅ 15.95 and x = -5.95. We cant have a negative side length so we can disregard that negative answer.
Which of the following is the rule for the geometric
sequence 1, 3. 9. 27, ...?
an = 3.39-1
an = 3.31
an = 1.32
an = 1.39-1
Answer:
[tex]a_{n}[/tex] = 1 . [tex]3^{n-1}[/tex]
Step-by-step explanation:
The n th term rule for a geometric sequence is
[tex]a_{n}[/tex] = a [tex]r^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = 1 and r = 3 ÷ 1 = 3 , thus
[tex]a_{n}[/tex] = 1 . [tex]3^{n-1}[/tex]

Find the 14th term of geometric sequence 5,-10,20,...
Answer:
Step-by-step explanation:
The formula for a geometric sequence is
[tex]a_n=a_1*r^{n-1}[/tex] where n is the position number in the sequence, a1 is the first number in the sequence, and r is the common ratio. For us,
n is 14, a1 is 5, and the common ratio (the number we multiply by each number to get to the next one in line) is -2.
[tex]a__{14}=5*(-2)^{14-1}[/tex] and

Calculate the surface area of a solid box in the shape of a cube with side length 6cm.
Answer:
216 cm^2
Step-by-step explanation:
A cube has 6 congruent, square faces.
Each face has side length of 6 cm.
The total surface area is the sum of the surface areas of the 6 faces, but since all faces are congruent, the total surface area is
SA = 6s^2
where s = side length
SA = 6 * (6 cm)^2
SA = 6 * 36 cm^2
SA = 216 cm^2

PLEASEEEEE ANSWER Gale wants to compare the cost of the events. Aquarium: $14.50 each ticket Carnival: c = 15.5 + 12f Wave pool: $16.75 each, but $12.25 each for groups larger than 4 Which of the claims Gale makes is true? The table represents all possibilities. The carnival always costs the least. The Aquarium always costs the most. (7, 101.5) is an ordered pair used to represent the aquarium cost.
Answer:
The fourth statement is true
Step-by-step explanation:
the table does not represent all possibilities, because the function is limited to zero tickets
Thus, this statement is false
the carnival never costs least, because the aquarium costs less, and the pool may cost even less if there is a group of 4
Thus, this statement is false
the aquarium not always costs the most, since it cost 14.50$ each ticket, while the wave pool may have tickets 16.75 each
Thus, this statement is false
the aquarium cost may be represented by the equation:
y=14.50x
now, we put in the ordered pair coordinates:
101.5=14.50*7
101.5=101.5
Thus, this statement is true
Answer:
correct 4 edge 2020
(7, 101.5) is an ordered pair used to represent the aquarium cost.
Step-by-step explanation:

Wave pool: $16.75 each, but $12.25 each for groups larger than 4

Sum of zeros in polynomial x2+4x+7 is
Answer:
-4
Step-by-step explanation:
Hello,
let say that [tex]x_1[/tex] and [tex]x_2[/tex] are two zeros of second order polynomial
it can be then be written
[tex](x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1*x_2[/tex]
So when we check this expression
[tex]x^2+4x+7[/tex]
we can say that the sum of zeros is -4
and the the product of zeros is 7
to note that in this example there are no real root of this equation
[tex]x^2+4x+7=0[/tex]
here, the zeros are complex numbers not real ones
if I have to solve it in [tex]\mathbb{R}[/tex] I would say that there are no zeros so their sum is not defined
if I have to solve it in [tex]\mathbb{C}[/tex] I would say that there are two complex roots and their sum is -4

Answer:
44 units
Step-by-step explanation:
When you perform a dilation on a figure, all of the side lengths of the figure get multiplied by the scale factor. This means that the perimeter is also multiplied by that scale factor. Since in this case that scale factor is 2, the new perimeter is 22*2=44 units. Hope this helps!
Answer:
44 units.
Step-by-step explanation:
Dilation is the transformation of an image's size by a scale factor.
The scale factor is given 2.
The rectangle has a perimeter of 22.
22 × 2 = 44
The perimeter for the resulting image is doubled by the scale factor of 2.

Mr. chen is parking in a lot downtown. The graph shows a relationship between the time and the total cost of parking. evaluate the input for a function of 2.
The solution to the question by reading the graph is:
''When x(Time of parking) is 6 hours, y(Cost of Parking) is 12 hours. ''
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given that;
Mr. chen is parking in a lot downtown. The graph shows a relationship between the time and the total cost of parking.
Now,
the line hits the point (2,6) and x represents the time and y represents the cost and continues to go at a constant rate of,

What is 3 3/4 as a fraction in its lowest term?
Please Explain it
Answer:
15/4
Step-by-step explanation:
This is because the denominator is 4 which means that there has to be 4 above it to make one:
4/4=1
So, with that being said, we do 4x3 = 12
But then we add 3 to the numerator(top number of the fraction) because the starting equation was:

what is the point slope form of a line with slope -4 that contains the point (-2,3)
Answer:
y -3 = -4(x+2)
Step-by-step explanation:
The point slope form of a line is
(y-y1) = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
y -3 = -4(x- -2)
y -3 = -4(x+2)
Instructions: Find the equation of the line through point (−4,1) and parallel to y=−12x−2. Use a forward slash (i.e. "/") for fractions (e.g. 1/2 for 12). Y=
Answer:
y = - 12x - 47
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 12x - 2 ← is in slope- intercept form
with slope m = - 12
Parallel lines have equal slopes, thus
y = - 12x + c ← is the partial equation
To find c substitute (- 4, 1 ) into the partial equation
1 = 48 + c ⇒ c = 1 - 48 = - 47
y = - 12x - 47 ← equation of parallel line
The required equation of the line is y = -12x - 47
What is the slope-point form of equation of the line?"The equation of the line having slope m and passing through points (p, q) is (y - q) = m(x - p)"
What is the slope-intercept form of the line?"y = mx + c, where m is the slope and c is the Y-intercept of the line."
For given question,
We have been given a point (-4, 1)
The required line is parallel to the line y = -12x - 2
Comparing above equation with slop-intercept form of the line.
m = -12
Let m1 be the slope of the required line.
We know that the slope of parallel lines is equal.
⇒ m1 = m
⇒ m1 = -12
Now we find the equation of the required line by using slope-point form.
Let (p, q) = (-4, 1)
By using slope-point form,
⇒ (y - q) = m1(x - p)
⇒ (y - 1) = -12(x - (-4))
⇒ y - 1 = -12x - 48
⇒ y = -12x - 47
Therefore, the required equation of the line is y = -12x - 47
