When solving a system of equations of A and B, we get no solution. When solving B and C, the solution is (0,3). When solving A and D, the solution is the origin. When solving B and D, the solution is (-1.5, 1.5). What is the solution when solving A and C? What are the equations of all the lines?
Answer:
You know that when solving B and c it is 0,3 and you know that when solving A and D the solution is the origin. Also when solving b and d it is -1.5,15 so D equals 1.5 and A equal the origin so solve from their

Aditya is celebrating his birthday. He invited his friends. He bought a packet of toffees/candies which contains 120 candies. He arranges the candies such that in the first row there are 3 candies, in second there are 5 candies, in third there are 7 candies and so on.
(a) Find the total number of rows of candies.(i) 12 (ii) 10 (iii) 14 (iv) 8
(b) How many candies are placed in last row? (i) 22 (ii) 21 (iii) 24 (iv) 18
(c) Find the difference in number of candies placed in 7th and 3rd row. (i) 8 (ii) 10 (iii) 12 (iv) 14
(d) If Aditya decides to make 15 rows, then how many total candies will be placed by him with the same arrangement? (i) 200 (ii) 150 (iii) 255 (iv) 210
(e) Find the number of candies in 12th row.(i) 21 (ii) 30 (iii) 25 (iv) 19
Answer:
(a) 10, (b) 21, (c) 8, (d) 255, (e) 25Step-by-step explanation:
(a)Total number of candies = 120
The number of candies in the rows form AP sequence:
3, 5, 7, ...The first term is a=3 and common difference is d=2
Sum of n terms:
S = 1/2n(2a + (n - 1)d)Substitute values and solve for n:
120 = 1/2n(2*3 + 2(n - 1)) 120 = 3n + n² - nn² + 2n = 120n²+ 2n + 1 = 121(n + 1)² = 121n + 1 = 11n = 10Correct choice is (ii) 10
(b) Formula for nth term:
a(n) = a + (n - 1)da(10) = 3 + 9*2 = 3 + 18 = 21 candiesCorrect choice is (ii) 21
(c) Use same formula:
a(7) - a(3) = a + 6d - a - 2d = 4d4d = 4*2 = 8Correct choice is (i) 8
(d) Sum of candies in 15 rows
S(15) = 1/2(15)(2*3 + (15 - 1)*2) = 1/2(15)(6 + 28) = 255Correct choice is (iii) 255
(e) Number of candies in 12th row:
a(12) = 3 + (12 - 1)*2 = 3 + 22 = 25Correct choice is (iii) 25

Answer:
(-8,4)
Step-by-step explanation:
System of Equations:
Solve the following system of equations by the substitution method:
5x - 6y = -64 [1]
y = 20 + 2x [2]
Substituting y from [2] in [1]:
5x - 6(20 + 2x) = -64
Operating:
5x - 120 - 12x = -64
Simplifying:
-7x - 120 = -64
Adding 120:
-7x = -64 + 120 = 56
x = 56/(-7) = -8
x = -8
From [2]:
y = 20 + 2(-8) = 4
Solution (-8,4)

Lin counts 5 bacteria under a microscope. She counts them again each day for four days, and finds that the number of bacteria doubled each day—from 5 to 10, then from 10 to 20, and so on.
Is the population of bacteria a function of the number of days? Explain your reasoning.
Answer: Yes, this is a function, and the function is:
population = y = f(d) = 5*(2)^d
Step-by-step explanation:
If the population doubles each day, we will have an exponential growth, that can be written as
f(d) = A*(r)^d
Where:
A is the initial population. (in this case 5)
r is the rate of growth.
d is our variable, in this case the number of days
then:
f(d) = 5*(r)^d
such that:
f(0) = 5*(r)^0 = 5
after one day, we should have the double of 5, this is 10:
f(1) = 10 = 5*(r)^1 = 5*r
10 = 5*r
10/5 = r
2 = r
Then the equation that tells the population of bacteria is:
y = f(d) = 5*(2)^d (at least for the first four days, we do not know what happens after that)
Is the population of bacteria a function of the number of days?
Yes, this is a function because for each input d, we have only one output y.

write an expression in factored form that is equivalent to the expression 1/8x+16
Step-by-step explanation: In order to factor an integer (the 8 in the fraction 1/8) we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5)
The number that each prime divides the original integer becomes it's exponent in the final result.
In the example: [tex]\frac{1}{8} x+16[/tex]
Prime number 2 to the power of 3 equals 8.
[tex]\frac{1}{2^3} x+16[/tex]
Now, we need to perform a multiplication. The following rule is applied: [tex]\frac{A}{B} C=\frac{AC}{B}[/tex]
In the example: [tex]\frac{1}{2^3} x+16[/tex]
The new factors in the numerator are: 1x.
Notice that all non-fractions are placed in the numerator.
The factors in the new denominator are: [tex]2^3[/tex]
[tex]\frac{x}{2^3} +16[/tex]
Now, we need to add the fractions. We use this rule: [tex]\frac{A}{B} +\frac{C}{D} =\frac{\frac{LCD}{B}A+\frac{LCD}{D}C }{LCD}[/tex]
The example involved 2 terms. [tex]\frac{x}{2^3} +16[/tex]
Note that 1 non-fractional term are treated as fractions with a denominator equal to 1.
The LCD is: [tex]2^3[/tex]
[tex]\frac{x}{2^3} +16[/tex]changes to[tex]\frac{x+(2^3)16}{2^3}[/tex]
We need to evaluate a power by multiplying the base by itself as many times as the exponent indicates.
In the example: [tex]\frac{x+(2^3)16}{2^3}[/tex] (the one in parenthesis)
Base 2 will be multiplied by itself 3 times.
2 x 2 x 2 = 8 ([tex]2^3[/tex] = 8)
[tex]\frac{x+8\times16}{2^3}[/tex] (Notice that [tex]2^3[/tex] is now 8 in the fraction.)
Lastly, we multiply the 8 by 16 in the fraction, [tex]\frac{x+8\times16}{2^3}[/tex]
8 x 16 = 128
[tex]\frac{x+128}{2^3}[/tex] (Notice that 8 x 16 is now 128 in the fraction)
Therefore, your answer is: [tex]\frac{x+128}{2^3}[/tex]

A bag contains 18 balls to green five black eight blue one brown one red and one white if 17 balls of a move from the bag at random what is the probability that a brown ball has been removed
Answer:
[tex]P(Brown) = 0.0556[/tex] or [tex]P(Brown) = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Total = 18[/tex]
[tex]Green = 2[/tex]
[tex]Black = 5[/tex]
[tex]Blue = 8[/tex]
[tex]Brown = 1[/tex]
[tex]Red = 1[/tex]
[tex]White = 1[/tex]
Required
Determine the probability of selecting a brown ball
This is calculated as thus:
[tex]P(Brown) = \frac{Brown}{Total}[/tex]
Substitute values for Brown and Total
[tex]P(Brown) = \frac{1}{18}[/tex]
The answer can be in fraction or solved further as;
[tex]P(Brown) = 0.0556[/tex]
